hippocampus Flashcards
choose which are the last abilities to mature in humans are:
- vocabulary
- processing speed
- long-term memory
- working memory
working memory and processing speed
which fucntion doesnt decline with the aging of hyppocampus
- vocabulary
- processing speed
- long-term memory
- working memory
vocabulary
how does the hippocampus age?
- get smaller
- retains same number of neurons
- retrieval gets weaker
- LPT doesnt last as long and isn’t strong as before
- retrieval gets weaker
- LPT doesnt last as long and isn’t strong as before
cerebrospanial fluit is produced by…
- pyramidal cells
- pericytes
- ependymal cells
- granule cells
- neurons
- endothelial cells
- basket cells
- granule cells
ependymal cells
line ventricles of the brain and the central canal of the spinal cord
define alzehimers
lost of neurons in various brain regions
first region affected by alzehimer’s is…
- frontal cortex
- cerebellum
- hippocamous
- temporal ortex
- parietal cortex
- limbic system
- amigdala
- striatum
hippocamus
ccerebral cortex degentation comes after hippocampus
choose the symptoms of alzeheimer disease:
- see patterns in things
- memory loss
- can’t process and perceive stimuli
- can’t construct their own form of language
- loss spontaneity
- speech problem
- trouble handling money
- poor judgment
- can’t create new memories
- loossing/misplacing things
- problems with response inhibition
- amnesia
- getting lost
- memory loss
- loss spontaneity
- trouble handling money
- poor judgement
- loosing/misplacing things
- getting loss
in alzehimer’s patients ventricles are enlarge because…
cerebrospinal fluid has taken up the space of the tissue cortex
which two drugs are use to treat alzehimer’s disease:
endomorphins
memantine (Ebixa)
methylphenidate
SSRI
fluoxetine
acetylcholinesterase inhibitors
memantine and acetycholinesterase inhibitors
which cells are the first lost in alzheimer:
- motor neurons
- basket cells
- stellate cells
- acetylcholinergic neurons
- bipolar cells
- interneurons
- glutamatergic neurons
- pyramidal neurons
acetylcholinergic neurons
function of acetylacholineric neurons:
- transmit sensory informations
- reegulate basal ganglia
- regulate the hippocampus
- encode a field place
- learn about reward
regulate the hippocampus
how does memantine and acetylcholinerase inhibitors work?
- memantine block NMDA (glutamate) receptors and slows diwn the exitotoxicity
- acetylcholinesterase inhibitors block the breakdown of acetylcholine, mitigating its lost
brain cholinergic ssytem is composed of…
- striatum and hippocamous
- basal forebrain and brainsteam tegmentum
- amygdala, hypothalamus, fornix and thalamus
- mammalial bodies, hippocampus, cingulate gyrus and orbitofrontal cortex
basal forebrain and brainsteam tegmentum
neuromodulatory functions of brain cholineric system are
memory, cognition, and arousal
nucleus basalis of MEynert is the last thing to die in Alzheimer disease: true or false
