AUTOMATIC DEVICE FOR RECORDING AND ANALYZING EVOKED BIOELECTRICAL BRAIN ACTIVITY OF TESTEE Russian patent published in 2005 - IPC

FIELD: medical engineering.

SUBSTANCE: device has means for acting upon object under study, means for recording responses having transducers connected to computer via signal input/output unit, photorecorder unit having programmed control mechanism and frame marker unit having in series connected control desk, frame marker, superposed responses photorecorder, programming unit and switchboard connected to control desk, means for acting upon object, means for recording responses and computer. Photorecorder programming unit has cam mechanism, the switchboard has relay circuits, the frame marker unit has means for recording treatment protocol and means for recording current events being tape drive with transparent tape coupled with tape drive with exposed film. The means for recording responses have magnetic tape recorder connected to control desk and transducers via switchboard. Tape recorder signal input is connected to microphone for recording vocal data describing current experiment condition and testee data.

EFFECT: enhanced effectiveness in recording biopotentials and creating feedback links among testees; wide range of functional applications.
