title: [Interneuronal functional connections in the canine sensomotor cortex].
abstract: Multiple unit activity (MUA) of the sensomotor cortex was recorded from chronically implanted semimicroelectrodes in dogs. The spike trains of 6-8 neural units were selected from MUA. The character and temporal parameters of interneuronal functional connections were examined by the method of computerized cross-interval analysis. For this purpose the autocorrelation and cross-interval histograms were constructed. One of the main results was complete absence of symmetrical central peaks (shared input). The functional interrelations of selected neurons were characterized by unilateral and bilateral nonsymmetrical excitatory connections with short (1-10 ms), middle (10-80 ms) and late (80-2000 vs) delays. The peculiarities of these interneuronal connections are discussed.
