AP PSYCHOLOGY

Detailed explanation-1: -Malnutrition slows the brain’s development, thinning the cerebral cortex and reducing the numbers of neurons, synapses, dendritic arborization, and myelination-all of which decrease brain size, which, in turn, challenges the brain’s functional properties.

Detailed explanation-2: -Toxic stress has the potential to change your child’s brain chemistry, brain anatomy and even gene expression. Toxic stress weakens the architecture of the developing brain, which can lead to lifelong problems in learning, behavior, and physical and mental health.

Detailed explanation-3: -Once the threat is over, cortisol levels decline and the parasympathetic nervous system slows the stress response by releasing hormones that relax the mind and body while inhibiting, or slowing, many of the high energy functions of the body.

Detailed explanation-4: -It’s not uncommon to feel disorganized and forgetful when you’re under a lot of stress. But over the long term, stress may actually change your brain in ways that affect your memory.
