Q

Nmda receptors trigger more blank intracellular signaling than ampa

A

Complicated

17
Q

Ionotropic glutamate receptors

A

Ampar, nmdar

18
Q

Metabotropic glutamate receptors

A

Group 1,2,3

19
Q

This blocks nmdar at resting membrane potential and is removed by depolarization

A

Magnesium

20
Q

Nmda receptorss are involved in blank because it is a synaptic coincidence detector

A

Learning/memory

Q

Excessive inflow of calcium through nmdar channels

A

Excitotoxicity

22
Q

Primary excitatory nt in the cns

A

Glutamate

23
Q

Glycinergic receptors are postsynaptic in motor centers of the blank and blank

A

Spinal cord, brainstem

24
Q

Gabaergic receptors are postsynaptic in the blank

A

Brain

25
Q

Gaba is permeable to blank

A

Chloride

26
Q

Glutamate receptors are concentrated at blank

A

Postsynatpic densities/ distal dendrites (like spines)

27
Q

Gaba receptors are concentrated at blank

A

Soma/proximal dendrites

28
Q

Electrical transmission is more prevalent in the cns before blank

A

Adulthood
