Document Summary

Hemmorrhagic stroke: rupture of arterial wall leading to bleeding within the brain, blood very toxic to neurons. Ischemic stroke: blockage of artery to or within the brain. Lack of oxygen (anoxia) leads to neuronal death: plaques that build up arteries to the brain stops blood from reaching the brain. Filled with cerebral spinal fluid instead of blood. Anoxic stroke: right: stroke in a smaller more specific part of the brain. Localized lesions may impair very specific types of cognitive and cognitive-motor functions. Just before the precentral sulcus: approximately 50% - sends about 50% of the movement signals to the spinal cord, pivotal role in movement control. Other areas that specifically send projections to the spinal cord (much less than from m1: parietal lobe. Supplementary motor cortex (sma: premotor cortex (pma) Movement can be directly produced only by a very specific region of the cortex (the motor cortex m1) Edouard hitzig: german physician viewed the brains of dogs.
