Sentences with phrase «superior colliculus»

The phrase "superior colliculus" refers to a part of the brain that helps with our visual responses and eye movements. It plays a role in directing our attention towards things we see and coordinating our gaze. Full definition
iPSC - derived RGCs also expressed genes involved in guiding RGC axons to their specific targets, and when cultured on aggregates made from mouse midbrain, RGCs elaborated long processes that were oriented towards superior colliculus (SC) cells, the target of RGC axons in the midbrain, but not inferior colliculus (IC) cells, a target of the auditory neurons.
