$1589.00 plus $35 shipping

Autogenic's 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.

Its convenient SensorPhone EEG electrode/headphone set (included) makes electrode hook-up so FAST AND SIMPLE, your patients can do it themselves in seconds.

And, with no software to learn, you can use the AT62 EEG the day you receive it. Technology that WORKS FOR YOU.

Portable. Both battery and line-powered. Complete with all accessories, including a carrying case

Alpha-Theta Features

8-12 Hz alpha and 4-8 Hz theta.
100-400 Hz EMG filter.
EMG artifact indicator.

Superior Feedback

Audio: The Alpha-Theta Trainer uses comfortable audio headphones to provide quality audio feedback while blocking-out distracting background noises.

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 猩).

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.
