Document Summary
Anatomy of the nervous system the case of rs. Was knowledgeable in movie and cinema topics. But he suffered a stroke: stroke = an interruption of blood flow to the brain that kills brain cells and causes neurological symptoms to appear suddenly, can occur at any age. The drug he used: t-pa (tissue plasminogen activator) breaks up clots and allows initiate any type of conversation) normal blood flow to return to the affected region. 85 billion neurons and 86 billion glil cells (support neural functions) (about a 1:1 ratio different than the 10:1 ratio we used to think!) Each neuron 15000 connections with other cells. Neurons in the cortex: organized in layers / clusters called nuclei". Within these nuclei / layers cells close together make fiber pathways ( tracts") The brain = plastic": aka can undergo many changes during a person"s life. Brain"s architecture = mediated by the persons genotype but its plasticity is mediated by an individual"s epigenetic factors.
