nucleus reticularis gigantocellularis

A segment of the reticular formation found at the level of the inferior olive in the hindbrain and containing large neurons. Its descending axons contribute to the reticulospinal tract, and activation of this nucleus inhibits motor neuron activity in the spinal cord, e.g., during sleep.
