4.2 Motion Flashcards
What is the route of the visual system after light hits the photoreceptors?
Optics –> Retina –> LGN –> straite cortex –> Beyond
Extrastriate Cortex
Responds to body parts, and is responsible for border ownership.
Performs more sophisticated processing than lines or edges.
Region of the cortex, bordering the primary visual cortex and contains multiple areas involved in visual processing.
Striate Cortex
Respond best to oriented edges
Smaller receptive fields
Border Ownership
A phenomenon that distinguishes the visual border formed between an object and a background.
ON and OFF cells
On response neuron fires more rapidly when light is shown
Off response neuron fires when light is shown on and off regions spatially separate
On center receptive fields respond to large bars
On center receptive fields respond to large bars
