PSYB51H3 Chapter Notes - Chapter 4: Principles Of Grouping, Illusory Contours, Visual Cortex
Document Summary
Beyond v1 is the extrastriate cortex, a set of visual areas so called because they lie just outside the primary visual cortex. These areas are named v2, v3, and so on, though they are not a simple chain of processing areas and the naming breaks down pretty rapidly. First, we might ask what makes a patch of cortex into a visual area in its own right rather than just being part of another large visual area. A classic, anatomical answer was that there are differences in the structure of the cortex that distinguish some areas. When researchers find another map of the field, they tend to consider the new map to be evidence for a separate visual area. A final criterion is that cells in an area might all be concerned with one function, and that function is different from what neighboring cells find interesting.
