title: The effects of movements on caudate sensory responses.
abstract: The aim of this experiment was to assess the effects of movement on somatosensory processing in the caudate nucleus. Units were recorded extracellularly in the caudate of awake partially restrained cats. Unit responses were evoked by either natural stimuli (brushing and skin indentation) or transcutaneous electrical stimulation. Response patterns evoked by stimuli presented when the cat was at rest were compared to responses evoked by similar stimuli presented when the cat was either making buccolingual movements or turning its head. In the majority of cases, movement suppressed caudate somatosensory responses. However, impressive augmentation of responses was seen in some cells with either type of movement.
