[Interaction between the projection (visual and somatic) zones of the cortex and the parietal association area after application of neurotropic drugs to them].
Recording of EPs and local application of strychnine and KCl on the associative parietal and projection (visual I, somatic I) neocortical areas of the cat under Nembutal anaesthesia, revealed distinct interaction of these structures. Their different mutual effects are being considered, depending on their modality and functional significance as well as on properties of the stimuli which activate the associative structures (the parietal cortex and the posterior lateral thalamic nucleus, LP). The data obtained confirm and develop the concept previously outlined by the authors on different types of interaction between the studied cortical areas, the ways of their realization at cortical and subcortical levels, and the specific role of LP in the process. The distinctions of joint activity of the projection areas from various types of their interaction with the parietal associative cortex are discussed.
