  • Title: [Conditioned reflexes to time and effective stimuli after extirpation of the parietal region of the cortex in dogs].
    Author: Mering TA, Mukhin EI.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1978; 28(4):700-8. PubMed ID: 695931.
    Abstract:
    Experiments on unrestrained dogs performed by the alimentary method showed that extirpation of the parietal cortex (field P) does not affect the previously elaborated and well stabilized conditioned reflexes to time, their reversal and temporal differentiation. The operated dogs retain their ability for relative perception of temporal intervals. Switching over of conditioned reflexes to time is disturbed. The conditioned reflexes to successive complex stimuli with simultaneous differentiation of their components are disturbed for a long time (up to seven months). Less disturbed are the conditioned reflexes to a simultaneous polysensory complex with parallel extinction of their components (within one month after the operation). An assumption has been made that the parietal zone of the cerebral cortex plays an important part in the mechanism providing for successive connections.
