Advanced Technology AT62
EEG Alpha-Theta Trainer is a simple, self-contained, portable EEG for use in
your office – or for your patient's use at home.
The AT-62 is now supplied with standard Gold ear and
scalp electrodes, paste, prep, and full instructions on using the 10-20
system for maximum EEG signal resolution.
And, with no software to learn, you can use the AT62
EEG the day you receive it. It's technology that WORKS FOR YOU.
- 8-12 Hz alpha and 4-8 Hz theta.
- 100-400 Hz EMG filter.
- EMG artifact indicator.
Alpha-Theta Trainer uses an internal speaker to provide quality audio
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.
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.
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.
