Document Summary

Lecture 10: october 9, 2014 close up on the primary visual cortex(continued) Feature analysis in the striate (old story: hubel & wiesel, 1965: types of cells (review) Simple; respond to one orientation (vertical, horizontal, diagonal). The cell has an excitatory center that is diagonally centered, and a periphery that is. Complex; respond to the combination of orientation and motion (line orientation that is moving). End stop; responds to a combination of orientation, width, and motion: organization: hypercolumns. Ocular dominance columns; which eye does the cell respond best to. Diagram on courselink: zeki addition: the blobs and interblobs. Within hyper column there are blobs and interblobs. Blobs are blobs of colour and the interblobs are the part without blobs. The newer story on the striate: spatial frequency analysis (not in the text: background concepts, contrast and how contrast is measured. Contrast is the difference in brightness from things that are side by side.
