WaveRider Operating Manual Connecting Brainwave Electrodes Put a small amount of skin preparation gel (NuPrep) on a finger. Rub the skin preparation gel into the earlobes and the electrode site(s) on the head. The skin preparation abrades the top dead layer of the skin making for lower skin impedance and a better connection. Wipe off any excess skin preparation with a tissue.
WaveRider Operating Manual Put a dab of conductive paste (Ten20) in each head electrode and in each cup of both ear electrodes. Attach an earclip to each earlobe. Make sure that each ear clip makes good contact with its’ ear lobe. You may need to gently re-bend the ear clips if they become bent, or no longer fully close. Use your fingers to move hair out of the way of the head electrode site.
WaveRider Operating Manual Tips for Electrode Use • If you adjust the electrodes, wait for the signal to settle. • Don't play with the wires while using the WaveRider. • A poor connection may get better if the electrodes remains on the head for a few minutes • A good electrode connection may go bad. If this happens try the following approaches listed in order of increasing effort: 1. adjusting the electrode and ear clips and waiting for the signal to settle, 2.
WaveRider Operating Manual Notes on Attaching Brainwave Electrodes Attaching electrodes is more of an art than a science. It is not unusual for new users of electrodes to have difficulty establishing a good brainwave electrode contact. Electrode contact is extremely important. If electrodes do not make a good contact the WaveRider will display random environmental noise rather than electrophysiological data.
WaveRider Operating Manual Insufficient amplitude: Environmental noise: Good signal: Changing Amplification The WaveRider has user selectable hardware amplification. Each range of amplification is numbered 1 thru seven in order of increasing amplification. The amplification is changed by raising and lowering the up and down arrow keys on the keyboard when a strip chart window has the input focus. The active window is the window with the input focus.
WaveRider Operating Manual Caring For Electrodes Ear and head electrodes should be carefully cleaned immediately after every use. Use hot running water and cotton swabs to clean the conductive paste from the head and ear electrodes. Warm and wet each head and ear electrode under hot running water while cleaning the conductive paste with a cotton swab. Be careful not to twist the ear clips out of position. The ear clips should close completely and the two halves should remain parallel.
WaveRider Operating Manual Brainwave electrodes can become oxidized from failure to clean after use, age, or exposure to air. Oxidation can be visible or invisible. Minor oxidation can be remedied by cleaning electrodes with alcohol, or by dipping in a liquid silver cleaning solution available at most drug stores.
WaveRider Operating Manual Electrode Placement There is a standard pattern for placing electrodes on the scalp for the measurement of brainwaves. This is known as the 10-20 system. Each electrode site has a name composed of a letter and a sub-script. Each letter (with the exception of C which stands for center) refers to the cerebral lobe over which the electrode is placed, i.e. T=temporal, P=parietal, O=occipital, F= frontal, Fp=pre-frontal.

WaveRider Operating Manual CHANNELS WaveRider collects data on biological channels that are named by letters. Channels A & B for the WaveRider jr./2CX and channels A, B, C & D for the WaveRider Pro. WaveRider sends MIDI data out on numbered MIDI channels 1-16. It is important that the MIDI channels specified do not conflict with each other. USE CATEGORIES WaveWare utilizes use categories to keep track of the type of data each biological channel is acquiring.
WaveRider Operating Manual FILE CREATION WaveWare can create three types of files: configuration (.cfg) files, archive (.bio) files and ascii (.txt) files. Configuration Files Configuration files store the templated setups that you see on your screen when you look at WaveWare. They include the settings for each window as found in that window’s dialog box. In addition they save global parameters such as colors, transform characteristics, and cycling.
WaveRider Operating Manual ASCII FILE OUTPUT (Exporting to a spreadsheet) Offline processed biological data may be exported to an ASCII (text) file. This data can be opened and further processed in a spread sheet or statistical analysis package. The streams of processed data stored in the ASCII file will correspond to the General Graphics Windows present in the configuration file when the data is exported.
WaveRider Operating Manual WINDOWS The screens in WaveWare are composed of windows. Each window has a set of properties that can be set in its' dialog box. Any window’s dialog box may be accessed by double clicking on the middle of the window with the left mouse button. Do not click on the titlebar, since this will maximize the window. What follows is a brief description of some of the windows and their associated dialog boxes in WaveWare .
WaveRider Operating Manual Strip Chart The STRIP CHART command in the BRAIN, HEART and MUSCLE menus opens a window that displays the raw biological signals , or displays the same signals as they are later replayed from an archive file. The strip chart display is especially helpful in monitoring the electrode connections, and making sure that the range of the WaveRider channel is set properly.
WaveRider Operating Manual Strip Chart Options Dialog Box CHA EL Choose among the WaveRider channels (or among the saved channels, if an archive file is being read); the chosen channels will be displayed in this strip chart window, one above the other. Some of the channel checkboxes may be grayed, indicating channels which have a different use category. If multiple channels are displayed in one window, those channels become Linked; the ranges of linked channels are always kept the same.
WaveRider Operating Manual Fast Bars and Slow Bars The FAST BARS and SLOW BARS commands in the BRAIN menu open windows that display the frequencies of the brain signals. Both windows derive their frequencies from a Fast Fourier Transform (FFT). The fast bars window calculates the FFT as fast as it can. The Slow slow bars window displays the frequencies of the brain signals averaged over a selected number of seconds.This averaging makes the slow bars display much easier to read and less jumpy.
WaveRider Operating Manual Bar Graph Options The Bar Graph Options dialog box allows you to change the appearance and characteristics of the Fast Bars and Slow Bars windows. Channels Choose among the WaveRider channels (or among the saved channels, if an archive file is being read); the chosen channels will be displayed in this bars window. Some of the channel checkboxes may be grayed, indicating channels that have a different use category.
WaveRider Operating Manual Spectrogram The spectrogram display makes it possible to view the frequencies of the brain as they have changed over a period of time. Selecting SPECTROGRAM in the BRAIN menu opens this window. Color or shading is used to depict the amount of power present in each of the frequency bands. The brighter the color, the more power. The frequencies are represented vertically from one to forty hertz.
WaveRider Operating Manual Spectrogram Options Dialog Box The Spectrogram Options Dialog Box provides the ability to change the appearance and characteristics of the Spectrogram window. Channels Choose among the WaveRider channels (or among the saved channels, if an archive file is being read); the chosen channels will be displayed in this Spectrogram window, one above the other. Some of the channel checkboxes may be grayed, indicating channels that have a different use category.
WaveRider Operating Manual GSR Graph Selecting GSR GRAPH from the GSR menu opens a window that displays the Galvanic Skin Response (GSR), or displays the same signal as it is later replayed from an archive file. The display is a graph of the skin conductance ranging from low (often associated with a lowered stress level), to high. Double clicking on the GSR Graph window opens an Options box, which provides the ability to change a number of settings affecting the display.
WaveRider Operating Manual GSR Graph Options Dialog Box The GSR Graph Options Dialog Box provides the ability to adjust the appearance and characteristics of the GSR Graph window. Mode Four types of display may be selected. The GSR graph may be drawn using only the DOTS representing the individual data points. The default mode uses SOLID areas for greater visibility. A continuous LINE may be drawn to represent the data, or a THICK line may be selected.
WaveRider Operating Manual MIDI MIDI stands for the Musical Instrument Digital Interface. MIDI is a protocol or language spoken between electronic musical instruments and computer based music software and hardware. MIDI sends messages that are composed of note and velocity information. The note number refers to the pitch of the note and consists of a number between 0 & 127. Velocity is the loudness or volume of the note. Velocity also varies between 0 & 127.
WaveRider Operating Manual MIDI STRATEGIES When a scale is chosen in the MIDI OPTIONS DIALOG BOX particular attention should be paid to the choice of range of MIDI notes. If the object is to make the output sound in scale the tops and bottoms of the range should be octaves, fifths or some other significant note in the scale structure. The MIDI note numbers and their corresponding notes are provided below. Middle C is note 60.
WaveRider Operating Manual To play a blues riff start at the root and go to the fifth or seventh in one octave for the range of the signal. To play a single pitch set the upper and lower note range to the same value. To play at a uniform volume set the upper and velocity range to the same value. To have the note get lower and softer with more relaxation switch the order of the note and velocity values.
WaveRider Operating Manual FFTS, DIGITAL FILTERS AND SIGNAL PROCESSING The Fast Fourier Transform (FFT) is a mathematical prism. Just as a prism splits white light into its component colors, an FFT splits a signal into its component frequencies. Another perspective is that the FFT sorts a signal into a set of frequency bins. The WaveRider's FFT sorts a signal into frequency bins one hertz wide. An FFT takes a window or set of data points and converts this time window of data into a set of frequencies.
WaveRider Operating Manual Transform controls the characteristics of the global FFT parameters used in WaveWare. Select TRANSFORM... from the OPTIONS menu in WaveWare. Windowing refers to a set of co-efficients by which the data coming into the FFT are multiplied. The Windows have been designed to optimize time-frequency resolution trade-offs. The logarithmicity factor changes the scaling of the output of the FFT.

WaveRider Operating Manual THE GENERAL GRAPHICS AND THE MIDI OPTIONS DIALOG BOXES The MIDI Options Dialog Box and the General Graphics Options Dialog Box are the essential elements of control in WaveWare. They are the means by which musical setups and graphs of processed data are created and modified. In addition the General Graphics Windows are responsible for exporting data as both ASCII and DDE streams. Both types of dialog boxes have many features and deserve close scrutiny.
WaveRider Operating Manual Which Numbers Get Mapped To What? The upper halves of both the MIDI Options Dialog Box and the General Graphics Options Dialog Box control the way a biological signal is processed. The lower half of the MIDI Options Dialog Box controls how this processed signal is mapped to MIDI parameters. The lower half of the General Graphics Options Dialog Box controls how this processed signal is displayed on a graph and ouput to ASCII or DDE.
WaveRider Operating Manual Signal Dynamics The slider bar represents a real time view of signal dynamics. It provides the ability to view the response of the signal to the selected settings. There are two general scenarios for using the slider.: 1. The signal should start out above or below the ends of the slider and move into the middle of the slider with some effort. This means that you start out below the threshold and move into an active area.
WaveRider Operating Manual MIDI OPTIONS DIALOG BOX CHANNELS The lettered checkboxes provide the ability to choose among the WaveRider channels (or among the saved channels, if an archive file is being read). If the GSR Input Mode is selected, only the GSR channel may be used as input, so the checkboxes are not shown. The spin control on the right provide the ability to choose among the 16 MIDI channels for output.
WaveRider Operating Manual SLIDER The slider in the middle of the dialog box is an important indicator of how well your input settings match the signal dynamics. The ends of the slider turn red when the signal exceeds the settings in the current setup. The slider does not reflect the signal dynamics until the apply button is clicked. Clicking apply and observing the slider and sound output after changing settings is a good habit to develop.
WaveRider Operating Manual GENERAL GRAPHICS OPTIONS DIALOG BOX CHANNELS The checkboxes provide the ability to choose among the WaveRider channels (or among the saved channels, if an archive file is being read. If multiple channels are displayed in one window, those channels become Linked; the ranges of linked channels are always kept the same. INPUT The Input list box offers a choice among the parameters of biological signals from the WaveRider, which are then graphed.
WaveRider Operating Manual GRID You may choose a grid indicating the value of the parameter being graphed, with or without the numerical values along the left, or you may choose a totally plain display. You may also choose to add the time in seconds, along with a grid. SPACING The default horizontal spacing uses one pixel per point. If x2 or x3 are selected, each point uses correspondingly more space in the window, making less data visible at one time.

WaveRider Operating Manual POWER IN PASSBAND Power in Passband measures the amount of power in a user selected frequency band. It is helpful for some people to think of a brainwave frequency band like a frequency band on the equalizer of a home stereo. Many stereos have a visual display of the spectral components of the audio output. This display generally has an array of leds. Each column of leds represents the amount of power in one part of the audio spectrum.
WaveRider Operating Manual There are three settings in the Power in Passband sub-dialog box, Range of Hz, Range of % Power, Transform timebase. Range of Hz: Specifies the upper and lower edges of the frequency band. The numbers represents hertz or cycles per second. The Range of % Power: sets the upper and lower bounds of power within the selected frequency band and is mapped to the MIDI, General Graph, ASCII and/or DDE output..
WaveRider Operating Manual RATIO OF POWER IN PASSBAND The Ratio of power in passband measures the ratio of power between two user selected frequency bands. Many neurotechnology protocols speak in terms of the ratio between two frequency bands. (e.g. alpha-theta, beta-theta). These algorithms allow the user to raise one frequency band while suppressing another band. This makes the output dependent on meeting two conditions one band high the other low.
WaveRider Operating Manual There are four set of settings in the Ratio of Power in Passband Sub-dialog box: Hz Range A : sets the upper and lower bounds of the "A" frequency band. The numbers represents hertz or cycles per second. Hz Range B: sets the upper and lower bounds of the "B" frequency band. The numbers represents hertz or cycles per second.
WaveRider Operating Manual DIGITAL FILTER Digital Filter extracts certain frequencies out of the brainwave data. Which frequencies are selected depends on the filter used. The names of each filter generally describe their frequency response. For example: 10-13_Hz-101 implements a 10 to 13 hertz 101 tap digital filter.
WaveRider Operating Manual There are three settings in the Digital Filter sub-dialog box: Filter: Selects the frequency range of the digital filter to be used. Range (uV): Defines the range of microvolts that will be mapped to the MIDI. General Graphics, ASCII or DDE output. mS: Defines the signal integration time in milliseconds. The default number of milliseconds is the reciprocal of the center frequency. A multiple of this number will give the best response.
WaveRider Operating Manual RATIO OF TWO FILTERS Ratio of Two Filters measures the relative amount of two frequency bands using digital filters. The ratio of the two bands is mapped to the output. These are the same frequency bands that are used in Digital Filter.
WaveRider Operating Manual There are five settings in the Ratio of Two Filters sub-dialog box: Filter A: Selects the frequency range of the digital filter to be used. mS: Defines the signal integration time in milliseconds for filter A. The default number of milliseconds is the reciprocal of the center frequency. A multiple of this number will give the best response. Filter B: Selects the frequency range of the digital filter to be used. mS: Defines the signal integration time in milliseconds for filter B.
WaveRider Operating Manual REWARD/SUPPRESS RATIO Reward/Suppress Ratio outputs the ratio of two digital filters (A and B), if certain conditions are met. Filters A, B and C must be above or below user-specified threshholds to satisfy the conditions. If the conditions are not met than there is no output. Conditions may be turned on or off for each filter. Typically the ratio of filter A to filter B will be used for the ratio of two brainwave frequencies such as alpha/theta, beta/theta, or SMR/theta.
WaveRider Operating Manual Bands A, B and C each have the same settings. Filter A, B or C: Selects the frequency range of the digital filter to be used. mS: Defines the signal integration time in milliseconds for filter A, B or C. The default number of milliseconds is the reciprocal of the center frequency. A multiple of this number will give the best response. uV: Defines the micro volt level of the threshold. Threshold Button: Controls how the threshold will be used.
WaveRider Operating Manual REWARD/SUPPRESS Reward/suppress outputs filter A if threshhold conditions for filters A and B are met.
WaveRider Operating Manual Filters A and B have the same settings. Filter A or B: Selects the frequency range of the digital filter to be used. mS: Defines the signal integration time in milliseconds for filter A or B. The default number of milliseconds is the reciprocal of the center frequency. A multiple of this number will give the best response. uV: Defines the micro volt level of the threshold. Threshold Button: Controls how the threshold will be used.
WaveRider Operating Manual DOMINANT FREQUENCY Dominant Frequency measures the dominant frequency of the selected range of brainwave frequencies, i.e. the frequency in the selected range that has the most power. The FFT is the source for the frequency information. Dominant frequency can be used in two ways. It can measure gross trends of brainwave frequency within a session. Alternatively it can also be used to measure gradual relocation of frequencies within a particular band.
WaveRider Operating Manual There are two settings in the Dominant Frequency sub-dialog box. Range of Hz to Scan: Selects the range of frequencies from which the dominant frequency is determined. It also sets the range of hertz that will be mapped to the upper and lower bounds of the MIDI, General Graph, ASCII and/or DDE output. The numbers represents hertz or cycles per second. The Transform Timebase: selects the rate of scanning in seconds for the time averaged fourier transform.
WaveRider Operating Manual COHERENCE Coherence measures the phase relationship between two raw brainwave signals. When the peaks and valleys of two brainwaves coincide they are in phase. Coherence measures this relationship by subtracting each raw data point from the corresponding data point of the second channel. The difference is then compared over a user selectable number of data points. If the difference is uniform the signals are more in phase than if the difference varies greatly.
WaveRider Operating Manual There are three settings in the Coherence Sub-dialog box. Coherence Range: Selects the range of Coherence (from 0-255) that will be mapped to the upper and lower bounds of the MIDI, General Graph, ASCII and/or DDE output. Sampling Window: Selects the number of raw data points of which the signal is compared. Sampling Interval(MIDI only): Sets how often MIDI notes are output. The number represents how many data points have to be collected before a note is output.
WaveRider Operating Manual HEART RATE The Heart Rate Input measures the heart rate in beats per minute. There are three choices from the Heart Menu: Strip chart, General Graph and Heart Rate. 1. 2. 3. Strip Chart displays the raw signal. General Graph allows you to output the heart rate as a general graph, a post session ASCII output or a live DDE output. Heart Rate is a digital display of the heart rate.
WaveRider Operating Manual Beats to Average: specifies how many beats to average for each reading. A high number will smooth out the beat to beat variability. Rate (beats/min): Set the range of Heart Rate that forms the upper and lower bounds of the MIDI note range, General Graph display or DDE output. Display Tenths: If turned on, displays the Heart Rate in units of tenths of heart beat per minute.
WaveRider Operating Manual GSR GSR measures the conductivity of the skin. This varies with the level of arousal of the autonomic nervous system. The GSR works by passing a minute amount of current through the body (<10 micro Amps). Although in reality more complicated, it is easiest to think of the GSR in terms of sweaty palms. When you are nervous or stressed your palms sweat. This raises the conductivity of your skin (makes it easier for electricity to pass through it).
WaveRider Operating Manual The GSR Sub-Dialog Box has one setting and one special button. Range of GSR: Sets the range of GSR values that will be mapped to the upper and lower bounds of the MIDI, General Graph, ASCII and/or DDE output. Copy from GSR Chart: Copies the uper and lower bounds of the GSR Graph into either General Graphics or MIDI. Copying of GSR may need to be done several times during a session with widely varying GSR.
WaveRider Operating Manual PEAK TO PEAK AMPLITUDE Peak to Peak Amplitude measure the envelope or power of a muscle contraction. It can be used to measure relaxation or play music with your muscles.
WaveRider Operating Manual There are three settings in the Peak-to-Peak Amplitude sub dialog box. Amplitude Range: Sets the range of power that will be mapped to the upper and lower bounds of the MIDI, General Graph, ASCII and/or DDE output. Sampling Window: Sets the number of raw data points over which Peak-to-Peak Amplitude input is processed. Sampling Interval: Sets how often MIDI notes are output. The number represents how many data points have to be collected before a note is output.
WaveRider Operating Manual NEUROSCIENCE: THE GENERATION OF BRAINWAVES THE AUTONOMIC NERVOUS SYSTEM The autonomic nervous system controls arousal . It consists of the sympathetic (fight or flight) and para-sympathetic (rest and digest) systems. It is not part of the central nervous system but forms a separate "visceral" system. The autonomic and central nervous system communicate primarily through the hypothalamus which also controls the pituitary, the master gland of the endocrine system.
WaveRider Operating Manual The para-sympathetic system if stimulated causes the: pupils to dilate nose to run heart rate to decrease force of contraction of the heart to decrease bronchi to constrict peristalsis to increase urine output to increase. These are all rest and digest responses. THE BRAIN The human brain has two hemispheres, three meninges and four lobes. The hemispheres are the right and left halves of the brain connected through the corpus callosum.
WaveRider Operating Manual On the parietal side of the rolandic fissure lies the sensory cortex which receives information about body position, muscles, touch and pressure from all over the body. The temporal lobe is involved in hearing, perception and memory. It also plays a part in language. The occipital lobe is involved in vision. The primary visual cortex is at the extreme posterior of the occipital lobe.
WaveRider Operating Manual BRAINWAVE GENERATION Brainwaves typically range from 20-100 micro Volts and from 1-50 Hertz. Alpha waves 8-12 Hertz are associated with a state of relaxed wakefulness. They are best recorded over the occipital and parietal lobes. Quite often alpha waves can be generated by simply closing the eyes. Beta waves12-18 Hertz are normally seen over the frontal regions and over the other regions during intense mental activity.
WaveRider Operating Manual APPENDICES WHAT IS DDE AND THE DDE SDK? The WaveRider DDE SDK consists of WWDDE.DLL and its associated header file and export library. Functions within the DLL allow a Windows application to easily establish a DDE link with WaveWare, over which the application can obtain data from WaveWare either through callback functions (DDE hot links) or by query (DDE cold links).
