pupal, Dialate or get smaller based on light
 lens, Accommodation- lens shape changes according to distance
Retina, inner lining on the back of the eyeball that contains the receptor cells sensitive to light, both cones and rods present.
Fovea, line of central focus, hold only cones: color.
Optic Nerve, Carries visual info to the Occipital lobe, but first to the thalamus. 

Optic Chiasm: where the nerves cross
Lateral Geniculate Nucleus: Area in Thalamus that interprets images]]> 2016-10-13 14:20:59 UTC https://padlet.com/jonahtja4784/6balemy3ujok/wish/130450748 jonahtja4784 https://padlet.com/jonahtja4784/6balemy3ujok/wish/130459587 Rods (b/w)
Cones( color)
20:1 Rods outnumber
peripheral vision relies on rods

Bipolar Cells: Specialized neurons connect to rods and cones

Ganglion Cells: Axons of these cells, made of optic nerve and sends info to thalamus specifically to LGN.

Ganglion Cells:
Magnocellur Cells (M cells): Detect Motion
Parocellur Cells: Detect color/ What item is

Acuity: Ability to distinguish fine details, Sharpness

Parallel processing: Processing of several aspects of a problem simultaneously.]]> 2016-10-13 14:46:59 UTC https://padlet.com/jonahtja4784/6balemy3ujok/wish/130462844 jonahtja4784 https://padlet.com/jonahtja4784/6balemy3ujok/wish/130737720 Feature Detectors: Hubel and Weisel: Neurons in the visual cortex respond to specific features.

Wavelength: the distance from one wave to another

High Frequency: Short wavelength, blueish colors, high pitched

Low Frequency: Long wavelengths, reddish colors, low pitched sounds.

Amplitude: the height of a wave length
Large amplitude: Tall wavelength, bright colors, Loud sounds
Small Amplitude: short wavelength, dull colors, soft sound.

Theories of Color Vision:
Young-Helmholtz Trichromatic THeory: three different colors. separate cones separate colors. Can't explain the afterimage.

Opponent-Process Theory (Hering): threee kinds of cones working in pairs.]]> 2016-10-14 13:49:07 UTC https://padlet.com/jonahtja4784/6balemy3ujok/wish/130737720 jonahtja4784 https://padlet.com/jonahtja4784/6balemy3ujok/wish/131155146 2016-10-17 14:26:14 UTC https://padlet.com/jonahtja4784/6balemy3ujok/wish/131155146 jonahtja4784 https://padlet.com/jonahtja4784/6balemy3ujok/wish/132707139 5 million receptors in your nose: olfactory sense, memory is correlated with memory.

Taste: gustation, salty, sweet, bitter, sweet, and umami

Skin: pressure, tempurature, and pain
Brain most sensative to unexpected stimuli.

-Drilling through the skulls, very invasive, Splits a family apart,


After receiving cochlear implants what are some of the benefits and struggles that are experienced?
-Lets you hear and have a chance at a normal life, not quite the same speech as all others, communicates with both the def world and the hearing world,
