The EEG Alpha-Theta trainer is a self contained portable for office or home use. The unit provides both audio, via a built-in speaker, and visual biofeedback. The instrument is supplied with professional set of Gold Cup scalp and ear electrodes for maximum EEG signal resolution and the manual explains the proper electrode placement procedures, using the 10-20 system.
The Alpha Theta has two audio feedback modes. In one, the pitch increases or decreases proportionally with the EEG signal. In the other, the audio tones turn on or off to indicate threshold crossing. Feedback can be provided continuously, above or below threshold. Superior Feedback
Audio: The Alpha-Theta Trainer uses an internal speaker to provide quality audio feedback.
The Alpha-Theta Trainer has two audio feedback modes. In one, the pitch increases or decreases proportionally with the EEG signal. In the other, the audio tones turn on or off to indicate threshold crossing. Feedback can be provided continuously, above or below threshold.
Visual: The alpha and theta frequencies each have separate numerical and lightbar displays (autoranging from 0.1 to 99.9 µV).
You can select to display real-time EEG, time period averaged EEG feedback, or the PERCENTAGE OF TIME the EEG activity is in an alpha or theta state.
Advanced Feedback Features
The Alpha-Theta Trainer illuminates an LED and sounds a tone to indicate CROSSOVER (theta >alpha) has occurred.
The Last Value Attained (LVA) feature displays the maximum or minimum EEG value attained (as a target for patient motivation) while the lightbar provides real-time EEG feedback.
Statistical Capabilities
Simply by pressing a Statistics button, the Alpha-Theta Trainer provides both summary and intra-session statistics for the mean, max., min., SD, %SD, and the %Time or Threshold.
