Definition
The tectal plate is a region of the brain, specifically the dorsal part of the mesencephalon. This is contrasted with the tegmentum, which refers to the region ventral to the ventricular system. The tectal plate is responsible for auditory and visual reflexes.
It is derived in embryonic development from the alar plate of the neural tube.
