METHOD AND SYSTEM FOR USE IN MONITORING NEURAL ACTIVITY IN A SUBJECT'S BRAIN
First Claim
1. A system for use in monitoring brain activity of a subject, the system comprising a control unit comprising:
- a data input utility for receiving measured data comprising data corresponding to signals measured during a certain time period and being indicative of a subject'"'"'s brain activity originated from the subject'"'"'s brain during said certain time period, wherein said measured data is temporal and spatial data having one of the following configurations;
(a) comprising first temporal data being time and frequency function of said signals measured by a first measurement unit, and second spatial data for multiple locations within the brain provided by a second measurement unit with respect to the signals measured by the first measurement unit and (b) comprising first temporal data and second spatial data of said signals measured by the first measurement unit from multiple locations within the brain; and
a processor utility which is configured and operable for processing the measured data and generating data indicative thereof in the form of a multi-parameter function presenting a relation between frequency and time data of said signals measured by the first measurement unit for at least a selected set of locations from the multiple locations within the brain, and for analyzing said relation and identifying a subject-related signature corresponding to the subject'"'"'s brain neural activity, said signature therefore corresponding to high spatial resolution of the signals measured by the first measurement unit, enabling use of said signature for further interpretation of a brain functional state of said subject by using the first measured data.

37. A method for use in performing neurofeedback, comprising:
-
providing a predetermined EEG signature corresponding to a certain stimulus, said predetermined EEG signature being indicative of a spatial neural activation of one or more regions in a subject brain corresponding to individual functions of the brain while under said certain stimulus and thus corresponding to a predicted certain activity state related to a given stimulus; applying said stimulus to a subject to activate said one or more brain regions; and performing EEG measurements on the subject'"'"'s brain for a controlled time period while under the application of the certain stimulus, and generating EEG data thereof; processing said EEG data using said predetermined EEG signature to identify one or more parameters indicative of neural activation of said one or more regions by said given stimulus, and selecting from the EEG data EEG signals related to said neural activation. - View Dependent Claims (38, 39, 40, 42, 44)
