Question

Quizplus · Accepted Answer

The cerebral peduncles are fiber pathways that connect the primary motor cortex with motor neurons in the brain and spinal cord. They also carry ascending sensory information to the thalamus. The olivary nuclei are involved in motor coordination, the nucleus gracilis is involved in sensory processing for touch and proprioception, the reticular formation is involved in regulating arousal and sleep-wake cycles, and the substantia nigra is involved in movement control and reward processing.
