What is in the gray commisure?

The gray commissure is a thin strip of gray matter located in the center of the spinal cord, connecting the two halves of the spinal cord's gray matter. It contains neuronal cell bodies and is involved in the communication between the left and right sides of the spinal cord. The central canal, which is filled with cerebrospinal fluid, runs through the gray commissure. This structure plays a role in relaying sensory and motor information across the spinal cord.
