Document Summary
The capacity of the brain to reorganize itself. Neural plasticity: the potential for the brain to adapt to injury, or to structurally change due to environmental experience. Phenotypic plasticity: the part of the genotype that is expressed. Physical exercise can induce dramatic changes in the brain. With experience and becoming an expert in an area, we can see changes in the brain. Clings to the brain quite tightly, following the folds. The folded outside surface of the brain; cortex = bark . The folds are meaningful and create important landmarks in the brain. Rupture in an artery, a narrowing of the artery or clots could cause stroke. Certain parts of the brain that are myelinated. Ventricles: responsible for making csf, which generates buoyancy, is a shock absorber, and can help clear waste. Creates two symmetrical - and asymmetrical - halves. Most structures in the brain are bilateral (both sides) very few straddle the midline.
