Computational model of ocular dominance in a recurrent V1 network with homeostatic structural plasticity

Neurons in the primary visual cortex (V1) of mice typically respond more to the contralateral than to the ipsilateral eye. However, this ocular dominance (OD) bias changes during adolescence, depending on visual experience. So far it is not fully understood how the experimentally measured OD distributions of V1 neurons emerge, and what is the mechanism of their change during the critical period. I investigated these questions using numerical simulations of a recurrent V1 network model under visual stimulation, assuming that homeostatic structural plasticity drives its development. I also studied how altered visual input in monocular deprivation (MD) experiments perturbs the regular development.
