Definition: Tissue located on the ventral side of the optic tectum, that contains the cell bodies of most tectal neurons. It is adjacent to the tectal ventricle and opposite the eminentia granularis of the cerebellum. It also contains a neurogenic niche and has hypothalamic inputs. The dendrites of neurons from the periventricular grey zones project their apical dendrites to the stratum opticum and stratum fibrosum et griseum superficale and synapse with retinal axons that project to these layers.
