An Adaptive Sensory Fusion Approach for the Superior Colliculus

Conference paper

Abstract

Fundamental questions arise when trying to combine different sensory information into a coherent representation. The answers relate to every domain within cognitive science. A wellestablished brain structure to approach these questions is the Superior Colliculus. Visual and auditory stimuli merge into a common coordinate system to initiate saccadic eye movements. The coordinate transformation of head-centered auditory stimuli into a retinotopic or motor error coordinate system was modeled in a neural network. Auditory and visual space are short-term connected by every physical stimulus in the environment. This association was used in order to develop the transformational network through experience. Simulations with local Hebbian learning also revealed characteristics of the fusion process concerning eye position signals and topographic maps.
