BioExplorer Software v1.7

BioExplorer is a Windows program for real-time biophysical data acquisition, processing, and display. The real power of BioExplorer comes from the ability to connect signal processing and display objects any way you want. Includes BioReview for post-session review recording the time, date, electrode locations, and subject name with each session. Green Dongle.

BioExplorer Features

• Flexible audio and video feedback using sound, music, tones, and video that respond in real time to physiological signals.
• Real-time signal visualization with meters, bar graphs, oscilloscopes, trends, and frequency displays.
• Frequency-based EEG training tools including bandpass filtering, dominant frequency detection, and power ratio calculations.
• Custom threshold-based feedback with manual or automatic thresholds, percent-success targeting, and range-based goals.
• Mathematical signal processing using user-defined expressions to combine, compare, or transform signals.
• Multi-signal analysis including coherence and correlation between channels.
• Hardware-agnostic signal input through source objects that represent channels from supported devices.
• Multi-monitor session layouts using a detachable second instrument window for flexible clinician and client displays.

Media & Feedback Output

• Audio Player plays audio files including MP3, WMA, WAV, and MIDI, with volume and play/pause controlled by one or more signals, optional left, right, or stereo channel output, and support for playlists.
• CD Player plays audio CDs with signal-controlled volume and play/pause.
• DVD Player plays DVD media with signal-controlled volume and play/pause.
• Video Player plays video files such as MPEG, WMV, and AVI, supports playlists, and allows signal control of volume and play/pause.
• Continuous MIDI plays a sustained MIDI note while enabled, allowing external signal control of enable state, pitch, volume, and play/pause.
• Tone Generator generates a pure sine-wave tone with signal control of enable state, frequency, volume, and play/pause, and supports multiple instances for binaural beat creation.

Signal Sources & Acquisition

• Source represents a hardware device channel, such as a BrainMaster channel, and is used to bring real-time data into the signal diagram.

Signal Processing & Transformation

• Bandpass Filter allows frequencies between a specified low and high cutoff to pass while attenuating frequencies outside that range, outputting both the filtered signal and its amplitude.
• Difference outputs the difference between the current signal sample and the previous sample.
• Expression Evaluator computes a user-defined mathematical expression based on one or more input signals.
• Threshold compares a signal against a manual or automatic threshold, supports percent-success targeting, and can be configured as a single or range-based threshold.

Signal Analysis & Metrics

• Averager calculates the average value of a signal over a specified time period.
• Standard Deviation calculates both the mean and standard deviation of a signal over a specified time period.
• Dominant Frequency identifies the frequency component with the highest amplitude within a signal.
• Mean Frequency calculates the mean frequency within a defined bandwidth.
• Power Ratio calculates the ratio of power between two frequency bands or the percentage of total power within a selected band.
• Coherence calculates the coherence between two signals.
• Correlation calculates the correlation between two signals.
• Counter counts signal events such as rising edges, falling edges, time high, or time low.
• Pulse Detector analyzes an EKG signal to determine the current pulse rate.

Visualization & Display

• Bar Graph displays the current value of a signal in a graphical bar format.
• Meter displays the current value of a signal using an analog-style meter.
• Oscilloscope displays one or more signals over time.
• Spectrum Analyzer displays the frequency spectrum of a signal using spectrogram, bin, compressed spectral array, or 3D visualization modes.
• Trend displays the mean value of one or more signals over a user-defined time window with a continuously scrolling time display.

Interface & Workflow

• Second Instrument Window allows display objects to be moved to a separate, detachable instrument window for use on a second monitor.

BioReview is a program for post-session review. This feature allows you to create and save reports which can be run on previously recorded sessions. You can also export session data in a variety of formats.

Enable 'gain equalization' filters in BioExplorer and BioReview.
These filters are tuned to each device (BrainMaster, WaveRider, etc.), and flatten their frequency response to give accurate readings over a wider range. For example, if a device's gain is down 10dB at 40Hz its filter will boost 10dB at 40Hz. As these filters introduce a small amount of delay (30-60mS) you have the option of disabling them when running a session. You can enable them when playing back a session, or in BioReview, to give accurate and consistent readings across all devices supported by BioExplorer. These filters also work on sessions recorded with previous versions of BioExplorer.
