Review of Neuroscience - Vosko Flashcards
oligodendrocytes
many:1 myelinization
in CNS
panicyte
circumventricular organ
like BBB
can regulate tight and loose junctions
tripartite system
presynpatic
postsynaptic
astrocyte process
telencephalon
cerebral cortex and basal ganglia
diencephalon
thalamus
hypothalamus
retina
mesencephalon
midbrain
metencephalon
cerebellum
pons
myelencephalon
medulla
CN
derived from neural crest
1, 1, 2, 2, 6
broca area
expressive aphasia
frontal lobe
angry patient
wernickes area
temporal lobe
fluent aphasia
word salad
- patient has no idea
hemineglect
lesion to parietal lobe
right lesion - left world doesn’t exist
basal ganglia
center of telencephalon
limbic system
emotions
sleep
parasympathetics - anterior hypothalamus
awake
sympathetics - posterior hypothalamus
ruler of autonomics
hypothalamus
micturition center
in pons
proprioception
cerebellum
dopamine centers in brain
VTA
substantia nigra
nissl body stain
shows cell body
RER
DCML nuclei
cuneatus - upper limb
gracilis - lower limb
vibration, proprio, 2 pt discrim
DMCL
pain, temp, crude touch
ALS
sensory of head
VTT
to VPM
touch head info
ascends bilaterally
inside mouth I/L
face C/L
basal ganglia disinhibition
indirect pathway
- decreased GABA at subthalamic nucleus
- more glutamate to GPi
- more GABA to thalamus (inhibition)
papez circuit
tie memory to emotion
cingulate gyrus > parahippocampus > hippocampus > fornix > mamillary body > anterior nucleus of thalamus > cingulate gyrus
working memory
dental gyrus > CA3 > CA1 > subiculum > enterohinal cortex
phototransduction
11-cis retinal to 11-trans
activate transducin
activates cGMP phosphodiesterase
closes Na channels - hyperpolarize
bitemporal hemianopia
pituitary tumor at optic chiasm
scotoma
neuritis CN II
auditory pathways
cochlear nuclei
tracts go bilaterally
meyers loop
inferior optic radiation - lose superior visual field with lesion
baums loop
superior optic radiation - lose inferior visual field with lesion
hit back of head
bilateral scotoma
wallenbergs syndrome
PICA stroke
I/L loss pain/temp face
C/L loss pain/temp body
