Sounds, signals and space maps

Abstract

The auditory system transforms information from one frame of reference into another to create a map of space in the brain.

Unraveling circuits of visual perception and cognition through the superior colliculus

“…Interestingly, the map of auditory space in owls and monkeys scales to follow the topography of the retinal map in the SC, a scaling that is not predicted by the topography of auditory spatial cues. Indeed, the auditory map is calibrated and aligned in the SC during development in owls and ferrets based on a visual instructive signal, which in owls originates in the OT and reaches the inferior colliculus (Carr, 2002;Hyde and Knudsen, 2002). It is likely that other sensory maps in the SC are aligned following the same principle.…”
