Document Summary
Computation of visual motion: eye movements, using motion information, the man who couldn"t see motion. This class: chapter 8: next class: chapter 9 and 10. Last lecture on vision: rest of course will be on the other senses, midterm grades will be posted soon. Motion is a change in position over time. Start with two adjacent receptors: registers change in position. Incorporate a delay: accounts for change in time. Constructing a neural circuit for the detection of rightward motion. We need a time delay incorporated --> we want something like c. You need the delay to see if thing appears there after the delay. X represents a comparators: this kind of motion detector is described below. Fixed time limit --> attuned to speed. Reichardt motion detectors are tuned to particular speeds. If a moving object is too slow or too fast, then signals will arrive at the comparators at different times.
