Self-organization of local cortical circuits and cortical orientation maps: A nonlinear hebbian model of the visual cortex with adaptive lateral couplings

摘要

A nonlinear. recurrent neural network model of the visual cortex is presented. Orientation maps emerge from adaptable afferent as well as plastic local intracortical circuits driven by random input stimuli. Lateral coupling structures self-organize into DOG profiles under the influence of pronounced emerging cortical activity blobs. The model's simplified architecture and features are modeled to largely mimik neurobiological findings. [References: 58]
