Document Summary
The brain: the brain uses 25-30% of the body"s energy, neurons: ~ 100 billion; communicate across synapses via release of neurotransmitters. Increased myelination speeds signals and processing: thinking/processing occurs primarily in the cortex (top and sides, pre-frontal cortex: executive control center. Responsible for functions like planning, decision-making, coordinating complex activities, self-regulation. Reaches full maturity in the mid 20"s. Components involved in memory storage: memory: learners" ability to save things mentally, sensory register: perception/input (very short amount of time, working memory: responsible for conscious processing and encoding. This term has come to take over or replace the term short term memory . Working memory is a more descriptive name for what is happening when we use it. Where the action is in learning: making sense of new information, using prior knowledge stored in long term memory to make connections. Limited capacity (increases somewhat from childhood to adulthood: long-term memory: long duration storage; unlimited capacity.
