COGNISION? Product Brochure
The document discusses the COGNISION™ System by Neuronetrix, an investigational device not approved by the FDA for clinical use. It is designed for evaluating cognitive function using quantitative EEG (qEEG) and event-related potentials (ERP).
Specifications
The system includes calibrated insert earphones, active electrodes, and Hydro-Dot® Biosensors. It operates with 7 channels (Fz, Cz, Pz, F3, P3, F4, P4), a sampling rate of 125/250 samples/sec, a band pass of 0.3-35/70 Hz, and a CMRR of >130 dB.
Quantitative EEG (qEEG)
qEEG analyzes the spectral content of EEG to evaluate brain functions such as attentiveness and relaxation. It is useful for early detection of neurological diseases.
Event-Related Potentials (ERP)
ERPs are EEG components generated by sensory and cognitive processing of stimuli. They provide real-time biomarkers for cognitive processes and can indicate abnormalities in neurological or psychiatric disorders.
COGNISION™ ERP Viewer
This application allows for viewing and analyzing qEEG/ERP data, including raw and average waves. It supports power spectrum analysis, wavelet transforms, and automatic peak detection.
COGNISION™ Patient Manager
This module manages personal, clinical, and biomarker data, supporting collaborative research with features like HIPAA-compliant security and centralized biomarker databases.
COGNISION™ Protocol Editor
The system uses an online library of ERP protocols with auditory and visual stimuli. Users can share additional protocols.
COGNISION™ Test Admin
Tests are scheduled through the Patient Manager and can be performed at any site with a COGNISION™ System. The module provides real-time data display.
Applications
The system is applicable in cognitive research, large-scale therapeutic trials, and clinical investigations of cognitive disorders.
Biomarker Fusion Classification
This module assesses combinations of qEEG & ERP biomarkers, enabling rapid testing and validation. It features data fusion, feature fusion, and model validation.
Scientific & Clinical References
The document cites various studies and reviews related to EEG and ERP as biomarkers in cognitive and neurological research.
