Abstract
A process for analysing an electroencephalogram (EEG) signal representative of activity of a brain of a subject, including: (i) generating coefficient data for a signal representation of a portion of the EEG signal; (ii) generating, based on the coefficient data, cortical state data representing the brain's receptivity to subcortical input and input from other areas of cortex; (iii) generating cortical input data representing a level of subcortical input to the brain at a time corresponding to the portion of the EEG signal; (iv) generating, based on the cortical state data and the cortical input data, display data representing the functional state of the brain of the subject; and (v) displaying the display data on display means.
Claims28
A process for analysing an electroencephalogram (EEG) signal representative of activity of a brain of a subject, including:
- (i) generating coefficient data for a signal representation of a portion of said EEG signal;
- (ii) generating, based on said coefficient data, cortical state data representing said brain's receptivity to subcortical input and input from other areas of cortex;
- (iii) generating cortical input data representing a level of subcortical input to said brain at a time corresponding to said portion of said EEG signal;
- (iv) generating, based on said cortical state data and said cortical input data, display data representing the functional state of the brain of the subject;
- and
- (v) displaying said display data on display means.
(canceled)
A system for analysing an electroencephalogram signal representative of activity of a brain of a subject, including a processor module and display means, said module being adapted to:
- (i) generate coefficient data for a signal representation of a portion of said signal;
- (ii) generate, based on said coefficient data, cortical state data representing said brain's receptivity to subcortical input;
- (iii) generate cortical input data representing a level of subcortical input to said brain at a time corresponding to said portion of said signal;
- (iv) generate, based on said cortical state data and said cortical input data, display data representing the functional state of said brain;
- and wherein
- the display means is operable to display the display data in graphical form thereon.
