Document Summary
Inside the brain: a tour of how the mind works. 1. cerebrum > involved in remembering, problem-solving, thinking, and feeling, and it controls movement. It also fills up most of your skull. 2. cerebellum > this is at the back of your head and underneath the cerebrum, and controls coordination and balance. 3. brain stem > under the cerebrum but in front of the cerebellum. Controls automatic functions (like breathing, digestion, heart rate, and bp). Branches connect nerve cells at more than 100 trillion points > scientists call this network a neuron forest. the signals traveling through this neuron forest are what form the basis of memories and thoughts and feelings. Over time, experiences create patterns in signal type/strength, which explains how our real work is done on an individual level, as nt"s travel across the synapse. brains code thoughts, memories, skills, etc. Alzheimer"s changes the entire brain and leads to nerve cell death and tissue loss.
