Corpora quadrigemina is related to vision in rabbits.
Corpora quadrigemina is the brain structure responsible for vision formation in rabbits. The corpora quadrigemina is a part of the midbrain or mesencephalon. The corpora quadrigemina is located on the dorsal surface of the midbrain. The corpora quadrigemina is also known as the quadruplet body or colliculi.
The corpora quadrigemina consists of four elevated structures. They are two superior (rostral) and two inferior colliculi (caudal). Rostral means the anterior part of the head and caudal means the posterior part of the head.
Both the superior and inferior colliculi are composed of grey matter inside and white matter outside. The inferior colliculi involve in processing auditory information. On the other hand, the superior colliculi involve in processing visual information and controlling eye movements.
The superior colliculi is a layered structure consists of the superficial layers or stratum opticum and the deeper layers. Nerve cells of the stratum opticum receive visual information from the retina and process it. Nerves cells of the deeper layers are motor-related neurons and are responsible for eye movements.
The homologous structure involves in vision formation in non-mammalian vertebrates is the optic lobe or optic tectum.
The Hippocampus plays important role in the consolidation of short-term memory into long-term memory. It is located in the temporal lobe of the brain and mainly involves in learning, recognition memory, spatial memory, and navigation.
The Corpus Callosum is a thick nerve fiber present below the cerebral cortex in the brain connecting the right and left cerebral hemispheres. It is only present in placental mammals.
The Corpus Albicans is the degenerated form of the corpus luteum, an endocrine structure found in female ovaries.
