This article is about obex portion of the brain. For the communications protocol "OBEX" (Object Exchange), see OBEX. Obex is also a verb meaning "to throw in the way of" or "to hinder."
The obex (from the Latin for barrier) is the point in the human brain at which the fourth ventricle narrows to become the central canal of the spinal cord.
The obex occurs in the caudal medulla.
The decussating of sensory fibers happens at this point.
