2-sensation come from bottom up 
3- Top down processing can change how features are perceived because everyone has different perceptions.

-transparent protector
-place where light enter the brain
---Pupil
-adjustable opening in the center of the iris 
--Lens
-Transparent part of the eye inside the pupil that focuses light onto the retina (upside down) by changing it curvature 
--Retina
-inner lining on the back of the eyeball that contains receptor cells sensitive to light
--Blind spot
-Point where the optic nerve leaves the eye; no vision receptors here 
--Fovea
-Line of central focus, holds only cones.
--Optic Nerve
-Carries visual info to the occipital lobe but first the thalumus 
--Optic Chaism
-spot where nerves cross each other 
--Lateral Geniculate Nucleus (LGN)
-Are in thalamus that interprets images

-Cones see color
20 rods for every cone
-Bipolar cells-cells that are specialized neurons connect to rods and cones
-Ganglion cells-axons of these cells, made of optic nerve and sends info to thalamus specifically the LGN]]> 2016-10-13 14:39:17 UTC https://padlet.com/williamkut7627/9hbgm737u7j8/wish/130459734 williamkut7627 https://padlet.com/williamkut7627/9hbgm737u7j8/wish/130740026 Amplitude- Height of the wave length 
Large Amplitude-tall wavelength, bright colors, loud sounds
Theories of color vision- 
Young-Helmholtz Trichromatic Theory-Blue, Green, blue
Afterimage-When you stare at 1 or 2 colors, cones become satruated, then when you look at a white piece of paper you see the opposite colors due to saturation of cones
Young- Helmholtzs theory cannot explain afterimages because in a afterimage you see the opposite color
Colorblindness- Partial or total inability to perceive hues, Monochromats(black and white, Dichromats(r/g, y/b)
Trichromats (normal color vision)
Opponent-Process Theory
three kinds of cones that all work in pairs (paired with opposites; if one is stimulated the other is inhibited 
Both theories are correct]]> 2016-10-14 13:54:20 UTC https://padlet.com/williamkut7627/9hbgm737u7j8/wish/130740026 williamkut7627 https://padlet.com/williamkut7627/9hbgm737u7j8/wish/132709678 Olfactory- Receptor cells sends info to olfactory bulb to limbic system 
-Not to thalamus like other senses
-What happens if you get a cold
-Problems with sense of smell due to clogged receptor cells
-Gustation(taste)-smell, taste and texture goes into how we like or do not like food
-Skin-pressure, temperature, and pain
-Brain is most sensitive to unexpected stimulation
-kinestheses- sense of body parts and positions 
-vestibular sense- monitors head position and movement 
Pain- No one specific receptor to stimulus individual differences 
GATE CONTROL THEORY- "Neurological gate" in the spinal cord controls the transmission of pain to the brain.
