• our eyes send info to our photoreceptors, bipolar cells, and then gangleon cells that give it to our brain through the optic nerve
• The lens in our eye focuses light and accommodates to our surroundings
• Cones are less populated and can see color and detail
• rods are more populated and are our peripheral vision
• The Trichromatic color theory is that some nerve fibers in the retina are especially sensitive to red, green, and blue
• Opponent process theory: there are three opponent channels (rvg, bvy, and bvw) and only one can go at a time
• Dichromatism is when 2 of the 3 color cones are functional (usually green and blue)
• Monochromatism is when none of your cone cells work
• colorblindness is more common in men and is recessive
• The outer ear gathers sound
• the middle ear amplifies sound
• the inner ear does transduction
• your semicircular canals in your ear help with balance
• your ossicles are the Malleus, the incus, and the stapes
• red and orange have a longer wavelength than blue
• bright colors have a higher amplitude than dull colors
• high pitches sound has a shorter wavelength than low pitch sounds
• loud sounds have a higher amplitude than quieter sounds
• Sensorineural hearing loss is caused by damage to the inner ear /cochlea
• conduction hearing loss is caused by damage to the ossicles
• Place theory is that sound waves are picked up from different places in the basilar membrane
• Volley theory is that groups of nerves fire slightly out sync and the brain decode the timing
• frequency theory is that the amount of hertz are the amount of neural firings in the brain
• 80-90% of taste is smell
• prosopagnosia is face blindness
• blindsight is the neurological condition that allows people to perceive visual stimuli without being consciously aware of it
