- Of or pertaining to the tectum
The tectum (Latin: roof) is a region of the brain, specifically the dorsal part of the mesencephalon (midbrain).
ColliculiIn adult humans it is present only in the mesencephalon as the inferior and the superior colliculi.
Both colliculi also have descending projections to the paramedian pontine reticular formation and spinal cord, and thus can be involved in responses to stimuli faster than cortical processing would allow. Collectively the colliculi are referred to as the corpora quadrigemina.
Related termsThe term "tectal plate" (or "quadrigeminal plate") is used to describe the junction of the gray and white matter in the embryo. (, )
