[Space-time organization of recruitment in rabbit cerebral cortex]

The spatio-temporal organization of the recruiting responses in the cerebral cortex was studied in an acute experiment on alert rabbits. Local low-frequency stimulation of the thalamic central medial nucleus leads to the appearance of both "generalized" and "local" spindles. Temporal shifts of 0.1--2 sec. occur in the appearance of the "generalized" spindles. The performed analysis permits the assumption that under local stimulation the spatio-temporal dynamics of the recruiting response is connected with the appearance of several spindle pacemakers which differ in their characteristics, e. g. in the speed of the excitability recovery and in their interrelations.
