Document Summary
Medial intraparietal region; area 5 provides info about how body segments are positioned cells have preferred posture. Pmd might use info about current posture from mip to plan movement. Pmd cells active during delay period when rules needed to make appropriate movement to given cue. Basilary: supplies pons and cerebellum circle of willis: inter-connected arteries forms ring protective; can provide alternative routes of bf middle cerebral artery: branches to sub cortex, lateral hemi damage to one of the arteries: anterior medial longitudinal fissures caudate patterns of progression. 247: hemorrhagic: rupture of blood vessel caused by: aneurysm: dilation of vessel wall = prone to rupture. Na/k pump needs atp to maintain resting potential w in 5 min of ischemia = extracellular glutamate 8x: excitotoxicity: excessive glutamate may kill neurons. Na draws water into cell changes cell volume = osmotic lysis (in umbra) Ca activates proteases & lipase that degrade cell and may initiate apoptosis.
