Question

Quizplus · Accepted Answer

The cerebral peduncles are white matter pathways that connect the motor cortex with motor neurons in the brainstem and spinal cord. They are also involved in carrying ascending sensory information to the thalamus. The other structures listed (inferior colliculi, red nucleus, and tectum) are not directly involved in these connections.
