[The potentials of spectral-correlative methods for analyzing total brain electrical activity exemplified by a study of the electrosubcorticograms of dogs].

Temporal resolving ability is considered of spectral-correlative methods of analysis of summate electrical brain activity. It is shown that despite their inertia, incompatible in some cases with the brain "functional lability", the use of these methods is perspective for studying the typological properties of the higher nervous activity and the dynamics of functional states characterized by the time of about 100 s and more. The fact of stability of spectral characteristics of the summate electrical brain activity at prolonged realizations was found experimentally. Connection was studied between the level of the dog alimentary motivation and rhythmic activity in the amygdala.
