Vision Flashcards
Man blinded by a chemical explosion at the age of 3. Was able to “fix” his eyes, but still could not see.
Mike May
Series of monotone rectangles, appear lighter at edges
Mach Band Illusion
Cells in the Retina that are placed closest inside, send information to brain
Retinal Ganglion Cells (RGCs)
Cells in the Retina that support lateral interactions
Amacrine and Horizontal Cells
Cells in the Retina that carry information from photoreceptors to Retinal Ganglion Cells
Bipolar Cells
Rods and Cones that transduce light signals, located furthest outside
Photoreceptors
Process by which light strikes rhodopsin, resulting in the blocking of glutamate release
Phototransduction
a light-absorbing pigment molecule located in the disk of the photoreceptor
Rhodopsin
Photoreceptors that are highly sensitive to light, ideal for dim environments
Rods
Photoreceptors that are not sensitive to light, need more light to be activated
Cones
Types of cones?
Red, Green, and Blue wavelengths
Area in retina that corresponds to the center of gaze, where vision is sharpest
Fovea
Bipolar cells that are excited by light at center
On-cells
Bipolar cells that are inhibited by light at center
Off-cells
Capacity of an excited neuron to reduce the activity of its neighbors (stealing energy)
Lateral Inhibition
