Abstract
Cells in the red nucleus (RN) belong to two distinct neural networks: Small rostral cells (RNp) connect cerebral and cerebellar output to the ipsilateral inferior olive. Discharge of RNp cells is poorly related to movement. Large caudal cells (RNm) and smaller rostral lateral cells (RNpc) connect cerebellar output to motor and premotor structures in the contralateral brain stem and spinal cord. Discharge of cells in RNm and RNpc is well related to movement. RNm cells discharge strongly during limb movements that include digit use, and RNpc cells discharge strongly during movements of the neck, head, and proximal limb.
