Parts of the Brain
Parts of the brain
Term | Definition |
---|---|
Amygdala | processes emotions, especially fear coordinates physiological responses based off cognitive information from areas of the cortex (higher cognitive info) and the brain stem systems (lower metabolic responses) |
Basal Ganglia | movement regulation - initiation of movements, balance, eye movement, posture skill learning, habit formation, reward system |
Brain Stem | maintains homeostasis in the body by controlling autonomic functions (Ex. blood pressure, breathing, digestion, heart rate, perspiration, temperature), alertness, sleep, balance, startle response |
Broca's Area | language production (speech and signs) comprehension of complex syntax |
Broca's aphasia | inability to express language, halting speech repetitive speech, disordered syntax and grammar and disordered structure of individual words |
Cerebullum | 10% of brain coordination of voluntary movement, motor-learning, balance, reflex memory, posture, timing, sequence learning |
Corpus Callosum | connects and allows information to pass between right and left hemispheres |
split brain syndrome | left and right hemispheres cannot communicate subtle cognitive, movement, and perceptual difficulties |
frontal lobe | executive processes (decision making, planning, problem solving, thinking), voluntary motor movement, cognition, intelligence, attention, language processing, comprehension |
Hippocampus | early memory stage, spatial navigation, formation of long term president |
Hypothalamus | regulates autonomic functions (Ex, hunger, thirst, body temperature, perspiration, blood pressure, heart rate, shivering, pupil dialation, circadium rhythm, sleep) |
Limbic System | memory formation and storage, regulating emotion, processing smells, sexual arousal |
occipital lobe | vision |
synthesia | blended senses Ex. graphme color- letters and numbers are perceived to have specific colors |
Parietal Lobe | takes information from different senses to create one picture - perception and integration of somatosensory information (touch, pressure, pain, temperature), visual spatial processing, spatial attention, spatial mapping, number representation |
prefrontal cortex | executive processes (decision making, planning, problem solving, thinking) attention inhibition intelligence social skills |
Temporal Lobes | face/object recognition, perception, understanding language, learning and memory acquisition, emotional reactions, processes hearing |
thalamus | relays connection between cortex and brain stem (motor and sensory info), alertness, perception and cognition, attention, timing, memory, movement, consciousness |
Wernicke's Area | language comprehension in the left hemisphere of the brain |
Wernicke's Aphasia | inappropriate words and inability to understand spoken language trouble with synchronizing objects and ideas to words that signify them |
