The cortical projection from the pulvinar has been studied in the cat with the help of stereotaxic coagulation and silver impregnation methods. The pulvinar of the cat projects fundamentally into the gyri suprasylvius posterior and medius, lateral bank of the posterior lateral sulcus, middle ectosylvian and anterior sylvian gyri. The projection to the gyrus suprasylvius is topologically organized overlapping with the projection of the n. lateralis posterior. The question of the ending of degenerated fibers in the parasplenial gyri is discussed. The thalamic degenerated fibers are present in the deeper layers of the cortex. There are however regions in the posterior suprasylvian gyrus in which degenerated fibers are present in the molecular layer as well as in the deeper layers. This different topographic distribution of the endings of the thalamic fibers is discussed with relation to the problem of the “sustaining” and “essential” thalamo‐cortical projections.
