Document Summary
1. 1 - neuroscience in the twenty-first century: traumatic brain injury (tbi): damage to the brain that results from a blow to the head. Brain: a physical object, a living tissue, a body organ. Behaviour: action, momentarily observable, but fleeting (short) Brain hypothesis: brain is the source of behaviour. Neuron hypothesis: the unit of brain structure & function is the neuron (neuron make up the brain) Sensory connections to receptors in the skin. Sensory and motor connection to internal body organs and gut. Brain comprised of 2 major structures: cerebrum (forebrain): major structure of the forebrain that consists of two mirror-image hemispheres (left and right; literally, half a sphere) Enfolded by brainstem: central structure of the brain, including the hindbrain, midbrain, thalamus, and hypothalamus: responsible for most of our unconscious behaviours. Chapter 1: what are the origins of brain and behavior: cerebellum: major brainstem structure specialized for learning and coordinating movements. Assists the cerebrum in generating many behaviours (b/c of evident.
