Colliculus
Colliculus
Colliculus (pronunciation: /kɒˈlɪkjʊləs/), from the Latin colliculus, meaning "small hill", is a term used in neuroanatomy to describe small, protruding structures within the brain.
Etymology
The term colliculus is derived from the Latin word colliculus, which translates to "small hill". This term is used to describe the appearance of these structures, which protrude from the surrounding brain tissue like small hills.
Anatomy
There are four colliculi in the human brain, grouped into two pairs. The superior colliculi are involved in visual processing and are a major component of the tectum, while the inferior colliculi are involved in auditory processing.
Function
The superior colliculi are involved in the processing of visual information, including the control of eye movements and visual reflexes. The inferior colliculi, on the other hand, are involved in the processing of auditory information, including the localization of sounds in space.
