SOCI 1001 Lecture Notes - Positron Emission Tomography, Central Nervous System, Transcranial Doppler
Document Summary
The central nervous system and how it"s studied. Carries out reflexes, transmits messages between brain and body (pns) Different segments each control sensations and movements of specific parts of the body. Many issues regarding motor control never make it to the brain. Observation of people with known damage (postmortem identification) Affect brain function (normally utilized with animals) High temporal resolution / low spatial resolution. Identifying transporters and receptors associated with neurotransmitters. Sleep and arousal, respiration, cardiovascular function, digestion, attentional filter. Relay point for a variety of sensory inputs. Basic responses such as the dilating or narrowing of the pupil in response to the light intensity. Limbic system - emotion, motivation, learning, memory. Basal ganglia: movement and judgements that require minimal conscious thought. Lateral geniculate nucleus (lgn) - relay station for visual. 2 types of areas: primary and association. Reasoning, planning, speech, movement, emotions, and problem solving, control. Contains the motor cortex: area responsible for voluntary movement production.
