title: [Rol' of the frontal lobe in synchronizing biopotentials in different regions of the dog brain].
abstract: The role of the frontal cortex in formation of neocortical systemic processes has been studied by the method of sign correlation of the summate electrical activity. A distant EEG synchronization in the temporal and occipital zones sets in following strychninization of F2 zones (but not of Prc2 zones) in anaesthetized dogs or in cerveau isolé preparations. In dogs with elaborated conditioned reflexes a statistically significant distant synchronization of the neocortical EEG sets in during the delay period only in case of well expressed motivation (of hunger in case of food reinforcement, and of thirst in case of water reinforcement). No distant conditioned EEG synchronization was revealed in lobectomised dogs. The role of the frontal cortex in the intracerebral integration is discussed which is necessary for achievement of the forthcoming signal activity.
