Document Summary
It is the first visual area in the cortex. In humans it is medial and near the occipital cortex: v1 is tucked inside the cortex even though it is a very large area. It is surrounded by v2: v4 is mostly posterior, v5 and v6 also exist. Input - the magnocellular and parvocellular system from the lgn: the magnocellular system terminates in a specific part of layer 4, these systems terminate separately; the magno projects to layer 4c a, and the parvo projects to. Pyramidal cells are very prominent in layer 5. Stellate cells are like stars; they may be spiny with very prominent spines that are excitatory, and then there are non-spiny stellate cells as well: neurons have different response patterns. V1 (complex and simple cells: receptive field are not rectangular; this is just a representation. In the elongated region, with the minuses when light shines on them, the cell is inhibited.
