"Encephalan-AVS" software suite
for EEG and EP studies using audiovisual stimulation

To investigate perception mechanism and to detect individually important information multimodal stimuli are presented to a test person while analyzing EEG/EP.

The important peculiarity is subsensory stimuli presentation mode with specified masking stimuli that help to distract attention of a person being tested onto other images concealing the true purpose of studies and the content of subsensory stimuli used.

EEG/EP recording and all stimuli and markers are absolutely synchronized (synchronization is ensured with the help of special sensor or net-operated).

To fix reaction (pressing a button) of a person being tested to various stimuli, the Patient Button Unit is used.
