How Stress Changes The Brain
We tend to think of stress as an immediate problem: The boss hovering over our desks; the mad dash to the subway at the end of a long day. Chronic stress can shrink your brain Stressful life events could harm your brain's memory and learning capacity by reducing the volume of gray matter in brain regions associated with emotions, self-control and physiological functions. A 2008 study on mice found that even short-term stress could lead to communication problems among brain cells in regions associated with memory and learning. One stressful event can kill brain cells As we learn new information, we constantly generate new neurons in the hippocampus -- a brain region associated with learning, memory and emotion. University of California at Berkeley researchers found that the brain in a state of chronic stress generates more myelin-producing cells and fewer neurons than a typical brain would, resulting in excess myelin in the hippocampus.
