yläcolliculus
The yläcolliculus, known in English as the superior colliculus, is a paired structure in the dorsal midbrain that forms part of the tectum. It sits above the cerebral aqueduct and works in concert with the inferior colliculus to integrate sensory information and guide orienting responses.
Anatomically, the superior colliculus is layered. The superficial layers primarily receive direct visual input from retinal
Functionally, the superior colliculus plays a key role in visually guided behavior. It mediates reflexive orientation
Afferent connections include retinal inputs and various cortical and subcortical visual pathways, along with multisensory inputs
Clinical relevance of the superior colliculus is typically seen in disorders of gaze control and visually
