Brain Flashcards
what does the lateral fissure separate
parietal from temporal
why does the brain have so much surface area
because of the texture
what is significant about the frontal eye field
movement of the eyes; they have to do the same thing at the same time
what is significant about the frontal lobe
motor control; higher level of functioning
what is significant about the Broca’s area
speech is affected if area is damaged
what is significant about the temporal lobe
involves things with patterns and sounds
what is significant about the occipital lobe
it has everything to do with vision ; colors, patterns, characters
what is significant about the Wernicke’s area
it brings everything/ lobe together in the brain
what is significant about the parietal lobe
understands speech; allows us to read words to convey a message
which lobe takes the longest to mature
the frontal lobe
what does the gustatory cortex allow for
it is associated with taste
what is half of the motor cortex in the brain dedicated to
the hands and feet
what part of the brain is myleinated
the cerebrum
what part of the brain is unmyelinated
cerebral cortex
whats the purpose of the corpus callosum
it allows the left side of the brain to talk to the right side
which side of the brain is the dominant hemisphere for 90 percent of people
the left side
what does the non dominant side of the brain control
expressions, artistic ability, feelings, music , etc
if the non dominant side of the brain is affected, then what is affected the most
personality
what does long term memory require
physical change
what does short term memory require
an electrical circuit
what is the purpose of the hippocampus
it consolidates memories
how long does long term (synaptic) potentiation take
2-3 days of repeated recall
what does the basal nuclei do
produces dopamine and interacts with motor areas
why is production of dopamine important
its important for preventing things from happening; it doesn’t cross the blood-brain barrier
what does the motor cortex control
all skeletal muscles
what is the cerebellum involved with
coordination
where is the basal nuclei located
deep within the brain
what’s the importance of the pineal gland
it is where melatonin comes from; it follows the circadian pattern; it secretes hormones’
when do people make the most melatonin
in the winter which means we make less serotonin in the winter
what does a “shortage” of serotonin cause
depression
what is the purpose of the corpus callosum
communicating between the two halves of cerebrum
what is the purpose of the choroid plexus
makes cerebral spinal fluid
whats the purpose of the thalamus
its a relay station; filters out unnecessary signals
what is the purpose of the hypothalamus
it is involved with thirst and hunger, body temp regulation, and shivering; it also monitors the hydration state of blood
what’s the importance of the limbic system
it controls emotional responses and interprets information about odor ( odor brings about emotional response)
what does the limbic system include
parts of the frontal and temporal lobes plus the diencephalon
what’s the importance of the brainstem
it keeps you alive
