The use of the instantaneous frequency of electroencephalogram rhythms for the detection of latent epileptiform process

The relation between the presence of latent epileptiform process and the change of the instantaneous parameters of the signals of the electroencephalogram is established in the work. The analysis of statistical estimations of instantaneous parameters of signals of multichannel electroencephalogram of healthy subjects and patients with epilepsy is carried out. The most informative frequency range of electroencephalogram rhythms is defined. Information and meaningful statistical evaluation of the instantaneous parameters areproposed. The obtained practical results can be used to create a new method for detecting a hidden epileptiform process.
