The COGNISION System is for use by qualified clinical professionals in private practice offices or small clinical settings for the acquisition, display, analysis, storage, reporting and management of electroencephalograph (EEG) and auditory evoked potentials (AEP) information.

The COGNISION™ EEG/EP System is a combination device for reduced montage recording and display of electroencephalographic (EEG) and evoked potentials (EP) test data. The system uses elastic bands to accurately position 10 electrode pods around the head (7 recording channels, 2 linked mastoids, and 1 common). EEG signal amplification, conditioning, and A/D conversion is performed by electronic circuits closely coupled to the electrode pods through short flexible printed wires. The headset is connected by a cable to a handheld control unit and data acquisition box (HCU). A lithium-ion battery in the HCU is used to power the system. The HCU communicates via a wireless data link to a Windows PC to stream EEG data. HydroDot® Biosensors (from HydroDot Inc., and not included as part of this submission) are inserted into each electrode pod to electrically couple the electrode pods to the subjects scalp. Software on the PC is used to setup the tests and view and evaluate the resultant test data using standard EEG/EP display methods. Calibrated audiometric earphones (from E-A-R Auditory Systems) can be plugged in to the amplifier A/D converter box to deliver various auditory stimuli to produce evoked potential EEG responses.
