FORM FACTORS FOR THE MULTI-MODAL PHYSIOLOGICAL ASSESSMENT OF BRAIN HEALTH

摘要

A multi-modal physiological assessment device and method enables the simultaneous recording and then subsequent analysis of multiple data streams of biological signal measurements to assess the health and function of the brain. The multi-modal assessment system includes at least one channel of EEG brainwave data in combination with cognitive information that provide a two-dimensional data stream of (x(t), y(t)) of cognitive information; voice recordings; motion, position, and stability data; galvanic skin conductance; temperature of the subject; pulse-oximetry data, cerebral blood perfusion data, vaso-motor reactivity data, and the like. The collected data is processed to construct candidate features extracted from multiple biological sensor data streams and correlated with multi-modal signatures to identify data indicative of brain health, disease and injury.

主权项

1. A system for capturing multiple streams of biological sensor data for assessing brain health of a user, comprising:
a plurality of biological sensors adapted to collect biological sensor data from the user, said biological sensors including an active brainwave sensor that collects at least one channel of EEG brainwave data, and at least one of the following:
an accelerometer and/or a gyrometer that collects motion, position, and stability data to provide quantitative stability and balance measurements,a peripheral sensing device that collects cognitive information in the form of neuropsychological data comprising key board keystrokes, mouse clicks, and/or touch panel events to convey reaction time and accuracy information,a microphone that records human speech to capture verbal responses of the human subject during a battery of tasks to either cognitive challenges or auditory stimulations, anda camera or biosensor that records that records eye movements, eye saccade and other biometric identification information; an electronic module that simultaneously records biological sensor data collected by said plurality of biological sensors; and a stimulation device that applies at least one of a visual stimulant, an auditory stimulant, a gastronomic stimulant, an olfactory stimulant, and/or a motion stimulant to the user, wherein the plurality of biological sensors simultaneously measure the body's response to stimulants applied by said stimulation device for recordation by said electronic module.
