The cerebral cortex - Coggle Diagram
The cerebral cortex
temporal lobe
lateral portion of each hemisphere, near the temples
-
-
also contributes to complex aspects of vision, perception of movement and recognition of faces
tumor in the temporal lobe: elaborate auditory or visual hallucinations (whereas a tumor in the occipital lobe evokes only simple sensations such as flashes of light)
emotional and motivational behaviors - damage: Klüver-Bucy syndrome: previously wild and agressive monkeys fail to display normal fears and enxieties after temporal lobe damage
-
frontal lobe
primary motor cortex and prefrontal cortex - from the central sulcus to the anterior limit of the brain
precentral gyrus (primary motor cortex) is specialized for the control of fine movements, such as moving a finger
mostly control the contralateral part of the body, but also with slight control of the ipsilateral (same) side
-
-
parietal lobe
-
postcentral gyrus (posterior to the central sulcus) is the primary somatosensory cortex - receives sensations from touch receptors, muscle-stretch receptors, and joint receptors
monitors all the info about eye, head and body positions and passes it on to brain areas that control movement - the brain needs to know the position of the head, the tilt of the body, etc, to determine tha location of whatever you see
-
the binding problem
the question of how the brain combines activity in different brain areas to produce unified perception and coordinated behavior. for binding we need simultaneous stimulus (sight, sound)
