L33 Psych 330 Lecture Notes - Lecture 9: Extraocular Muscles, Superior Colliculus, Receptive Field
Document Summary
Startle evidence for importance of detecting nearby animals, evolutionary perspective. Important aspect of movement detection involves detecting motion on the retina. A neural circuit that detects motion of a spot across the retina has a delay b. We must also perceive motion when there is no retinal motion, like when we track a m object with our eyes. Proof with afterimage from a bright flash it is fixed on your retina but it lo its moving. More evidence for the role of eye movements. Bar moves across a receptive field normal response from single cell recor. Receptive field moves across the bar - reduced response. Inflow theory: relies on signals from extraocular muscles and retinal signals determine if something is moving across our field of vision or our eyes are m across it. According to inflow, we always have accurate info about our eye movements.
