Does the supplementary motor area play a part in modifying motor cortex reflexes?
Neuronal activity in the supplementary motor area was recorded from a monkey performing a trained motor task that required readiness for proper usage of sensory inputs. Thirty-two neurons exhibited activity changes, which supports the hypothesis that the SMA is part of the system involved in modulating responsiveness of the motor cortex to sensory inputs in association with learned movements.
