Monday 8/27 central nervous system Brain and spinal cord, the parts of the nervous system that's protected by bone i.e. brain, spinal chord Encased by skull and vertebrate bones peripheral nervous system neurons and nerve processed outside CNS Sensory connections to the receptors in the skin. .. i.e. touch, and sight Somatic system: motor connections to muscle autonomic: guts and intestines Sympathetic and parasympathetic Sensory and motor connections to internal body organs i.e. gut, heart. Lungs three different goals of neuroscience 1. Explore structure and function. .. basic scientists that discover new things 2. How structure and functions develops, changes, and adapts over time. ... developmental studies, health studies 3. Ultimate goal: to treat and cure medical disorders purpose of the brain To generate and control behavior "Normal brain generates normal results, but abnormal brain generates abnormal behavior and outcomes" some temporary and some permanent Most categories of "normal" is based on statistics, but there are still broad descriptions what is behavior? Things you do. Physical Can be observable Reactions Require muscle movement control: walking, talking, and smiling Covert muscle movements. .. planning, thinking, imagining unconscious behaviors Posture control based on your environment Saliva accumulation. Most can keep saliva in mouth without thinking about it Level of alertness Mostly learned behavior Sometimes inherited. .. i.e. walking is already inherited because human bodies formed to walk principles of nervous system functioning

1. information-processing sequence in the brain is "in. .integrate. .out" 2. Sensory and motor functions throughout the nervous system are separating 3. Inputs and outputs to the brain are crossed. 4. Brain anatomy and function displays both symmetry and asymmetry. However, diff sides do diff things 5. The nervous system operates by a juxtaposition of excitation and inhibition Neurons have a system for accelerating and for braking 6. The nervous system has multiple levels of function. Primary, secondary, tertiary 7. Brain components operate both in parallel and hierarchically 8. Functions on the brain are both localized in specific regions and distributed Language: localized in the left hemisphere Also based on visual, memorization, and other different integration from other systems localization of function Certain things the nervous system does can be localized. I.e. spinal chord in charge of legs Austrian anatomist: Franz Joseph Gall from 1700's Theory: phrenology Brain had different domains, but he localized 35 distinct domains Responded to different specific functions If exercised, that part of the brain grows Feeling/measuring bumps o the skull that can characterize a person Amativeness: ability to love
