Abstract:
1. A method for monitoring seizure activity in brain, the method comprising: acquiring brain wave signal data from a subject deriving at least one parameter set sequence from the brain wave signal data obtained from the subject, wherein each parameter set sequence comprises sequential parameter sets and each parameter set comprises values for two signal parameters comprising a first signal parameter and a second signal parameter, wherein the first signal parameter is a single value parameter indicative of the current frequency content of the brain wave signal data and the second signal parameter is a single value parameter indicative of the current amplitude of the brain wave signal data; determining a path formed by each of the at least one parameter set sequence in a parameter space wherein the parameter space is a two-dimensional coordinate system, and wherein a first axis represents values of the first parameter and a second axis represents values of the second parameter, thereby to obtain at least one path; calculating at least one evolution indicator, wherein each evolution indicator quantifies evolution occurred in the respective path formed in a given time period in the parameter space; and employing the at least one evolution indicator to produce an indication of seizure activity in the brain wave signal data.
