Pocket-Neurobics. The Pocket A3 is a 4 channel wireless and standalone bio-potential amplifier. It supports 2 channel EEG (with EMG artefact detection), pIR HEG and nIR HEG, all concurrently. As a standalone device it can provide feedback thru tones and chimes to headphones or thru some simple screen displays like 'pong'. As a wireless device it can provide bio-potential signals to biofeedback software applications (some designs are included in the accompanying CD). The unit also supports binaural beats. It is powered by 2 AA batteries supplied.
The Pocket A3 should not be used with gold (plated) electrodes - use pure silver, tin or Ag-AgCl electrodes only.
