Abstract

A set of brain data representing a time series of neurophysiologic activity acquired by spatially distributed sensors arranged to detect neural signaling of a brain (such as by the use of magnetoencephalography) is obtained. The set of brain data is processed to obtain a dynamic brain model based on a set of statistically-independent temporal measures, such as partial cross correlations, among groupings of different time series within the set of brain data. The dynamic brain model represents interactions between neural populations of the brain occurring close in time, such as with zero lag, for example. The dynamic brain model can be analyzed to obtain the neurophysiologic assessment of the brain. Data processing techniques may be used to assess structural or neurochemical brain pathologies.

Description

Technical field

[0001] The present invention generally relates to neurophysiologic analysis, and more specifically, relates to, but not limited to, the use of time series representation to analyze brain patterns. Background technique

[0002] Like any other organ in the body, the function of the brain needs to be evaluated to evaluate its health and disease status. However, unlike any other organs in the body, there is no better brain function test. Typical behavioral examinations include standard neurological examinations, psychiatric interviews, or neuropsychological tests. Electroencephalogram (EEG) can hardly provide any information unless there is a grand epileptic seizure or a serious disorder of brain function, such as being in a coma. Used to evaluate brain structure (such as magnetic resonance imaging (MRI)), chemical properties (such as magnetic resonance spectroscopy (MRS)), fluoro-deoxyglucose-based positron emission tomography (fluoro-deoxy- Glucose based positron em...
