SYSTEMS AND METHODS FOR THE PHYSIOLOGICAL ASSESSMENT OF BRAIN HEALTH AND THE REMOTE QUALITY CONTROL OF EEG SYSTEMS
First Claim
1. A system for calibrating and/or verifying system performance of a remote portable EEG system having at least one EEG sensor, comprising:
- at least one ground electrode;
a signal generator producing at least one channel of reference signals;
a wired cable assembly that connects the signal generator output to at least one EEG sensor and ground electrode; and
a programmed processor that generates test reference signals and collects responses generated by the EEG sensor to the test reference signals to confirm system calibration and and/or verify system performance of the remote portable EEG system.

Abstract
A system for calibrating and/or verifying system performance of a remote portable EEG system having at least one EEG sensor. Embodiments of the invention can provide various reference signals to calibrate and quality control the remote performance of the data acquisition EEG system. In addition a calibration cable connects a reference signal source to the EEG sensors to enable remote calibration and quality control assessment. Further, a diagnostic biomarker is included to assess the state or function of a subject'"'"'s brain and enables the classification, prognosis, diagnosis, monitoring of treatment, or response to therapy applied to the brain by measuring any one of a list of candidate features extracted from a given cognitive or sensory task, and measuring changes in the EEG feature and task combination over time, among multiple states, or compared to a normative database.

8. A system for assessing the state or function of a subject'"'"'s brain, comprising:
-
a portable EEG sensing device that acquires a subject'"'"'s EEG signal data during cognitive or sensory testing; and a feature extraction system that processes the subject'"'"'s EEG signal data to establish a noninvasive biomarker in the brain that enables the classification, prognosis, diagnosis, monitoring of treatment, or response to therapy applied to the brain by measuring an extracted EEG feature or EEG features from a measured EEG signal when conducting a predetermined cognitive or sensory task, feature extraction system further measuring changes in the extracted EEG feature or EEG features over time, among multiple states, or compared to a normative database. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
