ap psych 2.6 parts of brain

in charge of facial muscles used for speech. if damaged = brocas aphasia

responsible for creating meaningful speech. cognitive aspect of speech. if damaged = wernickes aphasia

above spinal chord, below pons. regulates autonomic functions ( cardiovascular system, breathing, etc. )

bridge between different areas of the nervous system. connects medulla with cerebellum. helps with sleep and dreams

base of brain in the back. maintains balance and coordination.

base of brain. contains medulla, pons, and midbrain.

what connects brain to the rest of the body. information highway.

within the brainstem, sends visual and auditory information to the appropriate structure for processing. relay station.

network of neurons that tunnel down the brainstem. main functions are arousal and sleep/wake cycle. also filters incoming sensory information.

a specific part of the reticular formation responsible for regulating arousal, sleep-wake transitions, and consciousness. So, the RAS is a subset within the broader reticular formation.

name of the brain parts that are NOT the brain stem + cerebellum. where brain processes information not just for survival. complex thoughts.

thin layer of billions of nerve cells that cover the outer layer of the brain. often called gray matter. plays a key role in everything

made up of nerve fibers that connect the two cerebral hemispheres. allows hemispheres to talk to eachother.

behind forehead. higher level thinking. contains prefrontal cortex and motor cortex.

controls judgement, foresight, complex thought, and more. part of frontal lobe.

part of frontal lobe, controls voluntary movement. left motor cortex controls right side of the body. right motor cortex controls left side of the body

visual representation of amount of brain area dedicated to specific body parts.

on top of head, receives sensory information ( touch, pain, temperature )

parallel to and touches motor cortex. registers touch, movement and sensations.

proportional model of body areas that take in sensory information

back of the head, contains visual cortex. known for processing visual information such as shape, color and motion.

allows person to be able to see. in occipital lobe

near temples, located above ears. contains wernickes area. helps with facial recognition.

part of the brain that allows for symbol recognition and reading. lets you turn letters on paper into language and auditory sounds. inside of parietal lobe.

located in temporal lobe. processes sounds.

takes sensory information and sends it to the forebrain for processing. also regulates consciousness

group of structures ( hippocampus, amygdala, hypothalamus, thalamus, and more but those are all you need to know for ap psych ). between brain stem and cerebral cortex. controls emotions, learning, and memory.

where memories are created and consolidated

emotional reactions such as fear and aggression. included in limbic system.

keeps body balanced ( maintains homeostasis). also drives important biological impulses such as thirst, hunger and sex. works with pituitary gland.

near the limbic system. controls pleasure and reward. associated with drug dependency.

group of bodies / structures involved in movement. damage = parkinson’s, cerebral palsy, huntingtons.
