Brain "That part of the central nervous system that is located within the cranium (skull). The brain functions as the primary receiver, organizer and distributor of information for the body.

V5a V5 Characterized by strong motion-directionally sensitive neurons with large receptive fields organized into columns. Some neurons respond to the whole rather than the component motion of moving plaid patterns. Implicated in the analysis of movement, and stereoscopic depth. Receives input from layer 4B in V1 and thick stripes in V2. Projects to Medial Superior Temporal Area (MST). Verruca A wart. Verrucous Rough; wart-like. Viscous Thick, coagulated; sticky or gummy. Verbigeration Stereotyped and seemingly meaningless repetition of words or sentences. We thank you for using the Medical Glossary to search for V5a.
