title: Polymodal sensory and motor convergence in substantia nigra neurons of the awake monkey.
abstract: Responses of substantia nigra (SN) pars compacta (SNc) and reticulata (SNr) neurons to sensory stimulation and movement were investigated in awake Macaca fascicularis. Concern was assigned to polysensory and sensory/motor convergence on the same cell, which were found in 12% and 9% of the neurons, respectively. Others were modality specific (35%) or unresponsive (44%). The convergence lends support to the notion that SN plays an important role in sensory-motor integration.
