AP PSYCH Chapter three

Central Nervous System

Processes+sends out instructions. Ex. moving hand after touching something hot

Peripheral Nervous system

connects CNS to body. Ex. Carries signals to muscles to move

Sympathetic Nervous System

Fight or flight; blood pressure and sweat

Parasymphetic

Calms body down

Cerebral Cortex

Responsible for complex experimental functions (planning+thinking)

Medulla

Vital functions; breathing, heart rate, regulates reflexes

Pons

Sleep and arousal

Cerebellum

Motor coordination

Amyglada

FEAR!! discriminations of objects needed to live (food, love)

Hippocampus

Memory storage(s); waking up areas of brain used when we encountered infornmation

Thalamus

Alertness, motor info, sight, hearing, sensory

Hypothalamus

Eating, drinking, sex

Reticular formation

walking, sleeping patterns

Broca’s area

producing and understanding speech.

Wernicke’s area

ability to process information&word recognition

Reflexes

Sensory motor responses that are innate, automatic and typically of short duration

Occipital lobe

Respond to stimuli/ “see”/detect

Temporal Lobe

Hearing, language, process memory

Frontal lobe

Personality, intelligence, control of voluntary muscles. Planning and reasoning

Association Cortex

Region of the cerebral cortex that is the sight of intellectual functions.

Action potential

positivley charged electical brief wave that sweeps down an axon

Resting potential

Stable, negative charge of an inactive Ion. 

Acetylocholine

Muscle movement/memory. Voluntary muscles

GABA

sleep and arousal

Glutamate

memory and memory.

Norepinephrine

fight or flight+ Alertness

Dopamine

pleasure/happiness. decreased fatigue

Seratonin

regulation of sleep, mood, attention, and learning

Endorphins

“Euphoria”- eliminate pain

Oxytocin

Love and social bonding

Brain lesioning

an abnormal disruption in the tissue of the brain resulting from inquiry or disease. Lesions mean taking part of the tissue or destroying it. 

Transcranial magnetic situation (TMS)

magnetic coils places over head, magnetic field around trigger action potential in neurons

virtual lesion

Following the burst of action potentials; activity in the targeted brain is inhibited.
