exam 5 Flashcards
memory
short term memory
long term memory
consolidation by the hippocampus
short term memory
working
electrical
stimulating nerve
Na+, K+
changing threshold
wont stick with you
long term memory
long term (synaptic) potentiation
time and recall
synapses that stimulated in particular order
structure formed
consolidation by the hippocampus
consolidates memories
compacts them
only sorting through same thing
area of brain with kind of info
with “memory loss”
actually, there is just more to sort through
ex) names over here, dates over there, numbers there, events there
basal nuclei
produce dopamine (inhibitory NT)- away from threshold- less likely to stimulate motor cortex and neuron
interact with motor areas
motor cortex
thalamus
cerebrum
doesn’t interact with muscle but earlier with the motor cortex
Parkinsons has lack of dopamine- cant stimulate libs to be steady
Diencephalon
thalamus
hypothalamus
infundibulum
posterior pituitary gland
pineal gland
thalamus
Relay information from spinal cord to proper part of brain
Filter out background stuff from sensor information on the way up to the brain
sword’s motor information on the way down
cerebrum→ thalamus
Goes down right portion of spinal cord
for motion intended
ex) right vs left foot
hypothalamus
temperature regulation
blood vessels
shivering
Cardiovascular responses
Hunger and thirst
Controls activities of pituitary gland
infundibulum
Neural messages travel through infundibulum
Connections between pituitary gland and hypothalamus
stem
Substances travel through the blood
posterior pituitary gland
only part
made of neural tissue
anterior pituitary gland is made of epithelial tissue- not nervous system
pineal gland
melatonin (sleep)
diencephalon
more during winter (sun going down)
serotonin
CNS NT
not destroyed by enzymes
precursor to melatonin
more melatonin= less serotonin (winter)
related to clinical depression
SAD: seasonal depression
less serotonin in winter
SSRI
selective serotonin reuptake inhibitor
treat depression
serotonin in the synapse longer
effects last longer
limbic system
includes part of frontal and temporal lobes plus diencephalon
parts of the brain working together
mostly smell
smell and emotions
smell is linked to emotion
interprets info about odors
brainstem
basic reflexes- keep alive
midbrain
pons
medulla oblongata
reticular formation and sleep
midbrain
reflex- turning toward sound
following object that goes across field of vision with eyes and head
pons
repiration-some
