A computer analysis of EEG intersignal reactions during the the acquisition of conditioned motor-food reflexes in dogs



A computer analysis of EEG intersignal reactions during the the acquisition of conditioned motor-food reflexes in dogs



Zhurnal Vysshei Nervnoi Deiatelnosti Imeni i P Pavlova 41(6): 1119-1129



Background electric activity was studied of different neocortex areas in interstimulus intervals at the stage of generalization during elaboration of motor alimentary conditioned reflexes in dogs. For this stage the appearance is typical of short-term (0.1-0.3 s) packs of high frequencies (above 40 osc./s) significantly exceeding the adjacent initial background by frequency and amplitude (along side with motor interstimulus reactions). The index of specific variation, elaborated by us, allowed to single out this EEG pattern in the initial realizations of the background activity during their input in the computer. With the purpose of further evaluation of the above phenomenon parameters non-standard approaches of computer analyses were used, directed to decomposition of the EEG curve into the system of oscillations and receipt of corresponding amplitudes frequencies distributions (maps). It was shown, the described high frequencies packs were localized on these maps in definite sufficiently compact places.
