title: Thalamic projection to motor area and area 3a of the cat cerebral cortex.
abstract: The distributions of thalamic neurons projecting to the motor cortex and cortical area 3a were studied in cat by means of the retrograde double-labeling technique using Nuclear Yellow (NY) and Fast Blue (FB) as tracers. Following injection of NY and FB into the motor cortex and area 3a respectively, the NY-labeled neurons were found to be mainly located in ventrolateral (VL) nucleus and FB-labeled neurons in ventro-posterolateral nucleus (VPL). However, these two kinds of neurons were intermingled with each other in the border area between VL and VPL. A small number of neurons were double-labeled by both NY and FB. They were also distributed in the border area. Some of them could often be found in centromedian and parafascicular nuclei.
