Polycyclic multigraphs that reflect rats’ different brain cortex regions ECoG amplitude and frequences relation-ratio were made using multiply regression and correlation methods. These multigraphs realize the task of the information signal from ECoG amplitude-frequencies features vizualization in the transient field, i.e. they represent the mapping method.
The structural analysis of the made polycyclic multigraphs allowed to suppose that brain reticular formation reorganizes ECoG rhytms generator work from delta- to alpha-diapazone.
