- All cell types except ganglion cells generate ---
- cells in retina that contact photoreceptors and bipolar cells
- peripheral, detect light, best for dim light
- proposed the heirarchical model of coding, suggesting that these lines become increasingly complex, until eventually you recognize complex stimuli
- perceptual systems must accommodate for multiple representations of a stimulus to produce --
- a process in interconnected neurons - inhibiting their neighbors produces contrast (detecting edges)
- Deficiency in the ability to see movement progress in a normal smooth fashion; Can be induced by a high dose of certain antidepressants
- also respond to a bar of a particular width and orientation, but may be located anywhere in the visual field, or moving
- semantic neuron that codes for a specific thing and responds every time you see that
- takes place when different cells have different thresholds for firing, stimulus intensities
- the space in which a stimulus will alter a neuron's firing rate
- the progressive loss of response to a maintained stimulus
- ---- differ in size, shape, and response to types of stimulation
- occurs when the receptors for sensory systems register energy from the external environment: sound, light, odors, etc.
- A decrease in perceptual response to a repeated stimulus
- color, central in retina, fovea, best for bright lights
- A system in the retina that operates at low levels of light
- a decrease in sensory response to a repeated stimulus
- occurs when the information from sensation is processed within the CNS
- A system in the retina that operates at high levels of light, shows sensitivity to color
