PSYCH 1XX3 Lecture 5: Form Perception II
Document Summary
Feature detectors: cells that are very specific at what stimulus they make them fire. Both are a form of ganglion cells, and are the first step to object recognition. Axons exit the retina via the optic nerve, travelling to the lgn and ending up in the primary visual cortex in the occipital lobe. Recorded the electrical activity in an individual neuron of the squid. Paved the way for other researchers to see how individual neurons respond to stimuli. Discovered a neuron in the optic nerve of a frog that responded only to moving black dots, called these cells bug detectors . Studied cells in the visual cortex of cats and monkeys. Awarded an honorary degree from mcmaster university. 1962, trying to learn what type of visual stimuli individual cortical cells. Microelectrodes were placed in the cortex of a cat, recording electrical activity of individual neurons responded to of light. Cat shown different types of visual stimuli flashes of lights, etc.
