How our Brain Forms Visual Maps (VIDEO)
Caption
Our brains map the visual world in a piece of the cerebral cortex that is not much larger than a credit card. These maps sample spatial positions with neuronal inputs that have circular receptive fields which responded differently to position, polarity, and which eye. Increasing the number of visual points improves visual sampling but also requires need for larger cortical areas and larger brains.
