[Study of thalamic input in the motor area of the cat cortex by means of retrograde axonal transport of horseradish peroxidase].
HRP-labelled neurons were studied in different thalamic nuclei projected to anterior pericruciate motor cortex of cats. Considerable concentrations of labelled cells were found in the rostral parts of relay nuclei (VL, VPL, VPM). A local type of distribution of such neurons in the associative MD nucleus was discovered as well. The quantity of HRP-labelled units in the intralaminar nonspecific nuclei (Cl, Pc, CM) was small and they were diffusively distributed. Some aspects of heterogenic thalamic afferentation to the motor cortex are discussed.
