VLSI Implementation of Barn Owl Superior Colliculus Network for Visual and Auditory Integration
Conference paper
Abstract
A bio-inspired silicon Mixed Signal integrated circuit is designed in this paper to emulate the brain development in Superior Colliculus of barn owl. For the juvenile barn owl, it can adapt localization mismatch to prism wearing. Visual and auditory maps alignment in Superior Colliculus is adjusted. Visual and auditory input information can recover their registration after several weeks’ training. A mathematical model has been built previously to emulate this process. Based on the model, we designed a VLSI circuit in 0.35μm CMOS process which has been fabricated. In this paper we present the chip test results of a silicon superior colliculus and show a novel method for adaptive spiking neural information integration when disparity is caused by the environment.
