Brachium colliculi

Brachium colliculi is a part of the human brain that serves as a connection between the superior colliculus and the lateral geniculate nucleus. It is a part of the visual system and plays a crucial role in the processing of visual information.

Anatomy

The brachium colliculi is located in the midbrain, specifically in the tectum. It is a white matter tract that extends from the superior colliculus to the lateral geniculate nucleus. The superior colliculus is a part of the midbrain that is involved in the processing of visual information, while the lateral geniculate nucleus is a part of the thalamus that is the primary relay center for visual information received from the retina.

Function

The primary function of the brachium colliculi is to transmit visual information from the superior colliculus to the lateral geniculate nucleus. This pathway is crucial for the processing of visual stimuli and the generation of appropriate motor responses. The brachium colliculi is also involved in the control of eye movements and the coordination of head and eye movements in response to visual stimuli.

Clinical significance

Damage to the brachium colliculi can result in a variety of visual disturbances, including blurred vision, double vision, and visual field defects. It can also result in difficulties with eye movements and coordination of head and eye movements. These symptoms can be caused by a variety of conditions, including stroke, brain tumor, and traumatic brain injury.
