16
Q

declarative memory is impaired by what nutrient deficiency

A

thiamine deficiency- causes damage in mammillary bodies

17
Q

synaptic plasticity

A

ability of neurons to modify strength of their connections

18
Q

LTP (long-term potentiation)

A

cellular model for learning and memory

19
Q

what does LTP induction depend on

A

NMDAR (glutamate receptor permeable to Na+, Ca2+)

20
Q

what is the name of NMDAR blocker/inhibitor

A

AP5

21
Q

what substance leaves its connection with NMDAR after membrane depolarization

A

Mg2+

22
Q

2 things NMDAR activation needs

A

1- postsynaptic membrane depolarization
2- binding of glutamate (which is released from presynaptic terminal)

23
Q

excitotoxicity

A

too much NMDAR activation = too much Ca2+ influx / tocixicity

24
Q

neuro structures that decrease as we age

A

brain size
brain blood perfusion
cognitive function
loss of neural connections

25
Q

neuro structures that increase as we age

A

glial cell activation, inflammation
oxidative stress
