The significance of the thalamic parafascicular complex in tracking processes in cats

In conditions of free behaviour, trace processes of various complexity degrees (conditioned reflexes to time, temporal prognostication and delayed behaviour) were studied in cats in norm and following electrolytic destruction of some thalamic structures. It has been shown that parafascicular nuclei of the cat thalamus take part in the control of temporal reactions characteristics, and the thalamus median centre provides for generalization function proceeding on the basis of complicated trace phenomena connected with events prognostication.
