Blindsight
|
-Cortical Blindness” The ability of a person who cannot see objects in his or her blind field to accurately reach for them while remaining
unconscious of perceiving them -The brain: receives sensory input but does not process it properly; usually caused by damage to the Striate Cortex Blindsight is probably due to preserved visual into extrastriate cortex – bypassing Primary visual cortex Conciously don’t realize that they are seeing because it bypassing visual cortex but the brain still processes it |
|
|
Primitive Visual System (person is not aware of information received from this)
|
- eye and head movements
-reaching with hands -other simple behavior |
|
|
Mammalian Visual System
|
- damage destroys perception of visual stimuli
- speech and thinking in words (consciousness) other complex behaviors |

|
split-brain operation
|
Brain surgery that is occasionally performed to treat a form of epilepsy; the surgeon cuts the corpus callosum, which connects the two hemispheres.
|
|
|
corpus callosum
|
The largest commissure of the brain, interconnecting the areas of neocortex on each side of the brain.

unilateral neglect
|
A syndrome in which people ignore objects located toward their left and the left sides of objects located anywhere; most often caused by damage to the right parietal lobe.
whole regions of space contralateral to their lesions do not exist. patients may deny ownership of their contalateral limb and also neglect parts of their own body. May not dress the contralateral side to leasion and may fail to groom their hair or shave parts of their faces on that side. |

Rubber hand illusion video
|
premotor cortex—a brain region that integrates vision and touch—lights up, during rubber hand illusion signaling the source of the illusion.
premotor cortex matches the look of the hand and the feel of the hand Because the brain relies more on vision than on tactile sensations, it may give precedence to input from the eyes and make the rubber hand seem real. |
