- lens
- ability to focus our vision, small muscles change shape
- retina
- images are focuse on back surface of eye.. contains rods and cones...what lets you see.
- vitreous humor
- aqueous solution..supports eye and serves as cushion
- cerebrum
- (cerebral cortex)(mammalian brain) big part of brain!
- cerebral cortex
- (mammilian brain)2/3 of neurons, covers almost entire brain, dark matter/white matter
- brainstem
- physiological processes...BREATHING
- cerebellum
- (reptilian brain) fight or flight
- visual cortex
- back of brain. occipital lobes, visual info is processed
- modular units
- neurons in the cortex, undergo a continuing "convo" thru electrical impulses
- left hemisphere
- language orginates
- right hemisphere
- motor skills
- temporal lobe
- after visual cortex has process the visual info, it carries out recognition process
- rod
- (black and white) monochrome vision
- cone
- color vision
- occipital lobe
- where the visual cortex is located
- blind sight
- ability to "see without looking" athletes make passes w/o looking
- optic nerve
- bundle of nerve cells that carries visual info from eye to visual cortex
- subliminal perception
- brain's ability to filter out visual info and only allow recognition of that input which is important (speed of words shown to people)
- severing corpus callosum
- 2 halves cannot communicate. see image with left eye, image is processed on right, cannot name b/c right visual cortex cannot communicate w/ left language. can draw object.
