Abstract

The
visual and auditory map alignment in the Superior Colliculus (SC) of barn
owl is important for its accurate localization for prey behavior. Prism learning or
Blindness may interfere this alignment and cause loss of the capability of accurate
prey. However, juvenile barn owl could recover its sensory map alignment by
shifting its auditory map. The adaptation of this map alignment is believed based
on activity dependent axon developing in Inferior Colliculus (IC). A model is
built to explore this mechanism. In this model, axon growing process is instructed
by an inhibitory network in SC while the strength of the inhibition adjusted by
Spike Timing Dependent Plasticity (STDP). We test and analyze this mechanism
by application of the neural structures involved in spatial localization in a robotic
system.
