BRAIN
Term | Definition |
---|---|
forebrain, midbrain, hindbrain | parts of the brain |
forebrain | contains the cortex, basal ganglia, limbic system |
midbrain | important for both sensory and motor functions |
hindbrain | contains the medulla, cerebellum |
medulla | near brain stem, controls heartbeat, breathing and swallowing |
reticular formation | system of nerves running from the hindbrain, and through the midbrain to the cerebral cortex |
reticular formation | controls arousal and attention |
reticular formation | beneath the brainstem |
cerebellum | controls balance and maintains muscle coordination |
pons | relays messages between the cerebellum and cortex |
pons | dreaming, arousal, coordination of the left and right side of the body |
hindrain | medulla, reticular formation, cerebellum and pons |
forebrain | the limbic system |
limbic system | located inside the brain |
limbic system | involved in emotions, motivation, memory and learning |
thalamus | relays information from sensory organs to cerebral cortex |
hypothalamus | regulates the amount of fear, thirst, sexual drive and aggression we feel |
hippocampus | learning, memory and ability to compare sensory information to expectations |
hippocampus | looks like a seahorse |
amygdala | influences our motivation, emotional control, fear response and interpretations of non-verbal emotional expressions. |
cingulate cortex | primarily cortical component of the limbic system |
cingulate cortex | involved in emotional and cognitive processing |
cortex | outermost part of the brain |
cerebral hempispheres | the two hemispheres of the brain |
occipital lobe | visual information and is connected to the eye muscles |
temporal lobe | coordinated with time |
frontal lobe | higher mental functions such as decision making, reasoning |
frontal lobe | located at the front portion of the head |
temporal lobe | contains the primary auditory area; |
temporal lobe | involves learning language |
parietal lobe | located above the occipital lobe |
parietal lobe | contains the soma sensory cortex |
somasensory cortex | sense of touch, sense of direction |
olfactory bulb | small portion that allows us to smell |
motor cortex | under frontal lobe |
motor cortex | contains the voluntary muscles |
corpus collosum | these are a thick touch of neural fibers that connects the hemispheres |
association areas of the cortex | made up of neurons in the cortex that are devoted to making connections between the sensory information coming into the brain and stored memories, images and knowledge |
BROCA'S AREA | located in the left frontal lobe that is devoted to speech production |
Paul Broca | the Broca's Area is named after him |
Broca's aphasia | if the broca's area is damaged, it will result to this |
aphasia | inability to do something |
WERNICKE'S AREA | located in the left temporal lobe and plays a role in understanding the meaning of words |
Carl Wernicke | the Wernicke's area is named after him |
right side of the brain | which hemisphere is controls the left side of the body? |
Roger Sperry | Split Brain Research |
Roger Sperry | pioneer in the field of hemisphere specialization |
left hemisphere | tasks that involve sequence and analysis (language, speech, handwriting, math) |
right hemisphere | processes information in a more global sense (perception, visualization, spatial perception, recognition of patterns, faces and emotional experiences) |
left brained | logical, sequential, rational, analytical, objective, looks at parts |
right brained | random, intuitive, holistic, synthesizing, subjective, looks at wholes |
in curing epilepsy, he cut the corpus collosum to study the function of each side in the brain | how did Sperry discover the 2 hemispheres? |
