[Participation of the ventrolateral thalamic nucleus in organizing visually controlled movements in the cat]

The role of the ventro-lateral thalamic nucleus (VLN) in organization of visual-motor coordination in cats is being considered. It is shown, that VLN destruction leads to inability to form new visual-motor coordination and only temporarily worsens previously elaborated coordination. Ventral and dorsal parts of VLN participate in organization of various types of movement: destruction of the ventral part tells upon rapid ballistic movements, whereas destruction of the dorsal part leads to disturbances of slow tracing movements of animal's limb.
