Problem
Our brain organizes the world using similar techniques across sensory modalities and motor functions. This includes maps of visual and auditory information from the world, as well as maps of our body gpresented in the cortex.
In 200 words or less. explain how the world is represented in (i) primary visual cortex, and (ii) primary auditory cortex, as well as how the body is represented in (iii) somatosensory cortex, and (iv) primary motor cortex. Note, I am not looking for the neuroanatomy, just the organization of the map, what areas are nearby in the cortex, and how neural tissue is proportioned for the given function. What is the common theme that explains how the amount of cortex is distributed in each of these three sensory modalities & motor functions' respective maps?
