Document Summary
It is 2-3 mm thick movement and size. Primary visual cortex, v1, or striate cortex furthest posterior in brain. All neocortex, including v1, contains six layers (i is on the surface, and vi is the deepest) V1 is the first place in the brain where cells receive signals from both eyes. Neurons are specialized to respond best to specific aspects of stimuli, such as orientation, These specializations can be demonstrated physiologically, by recording from neurons. Sliding a slit of light across the visual field caused neurons to discharge (cid:523)lots of ap"s(cid:524) They found that v1 neurons respond best to bar-like stimuli with specific orientations. Orientation selectivity moving bar/edge through a receptive field causing neurons to discharge (get. Spots of light do little to stimulate neurons in v1 excited) Cortical neurons fire in response to specific features of the stimulus, such as orientation or. Therefore, these neurons are called feature detectors.
