Flashcards in Ch 10 - Synaptic Integration in CNS Deck (23):
0

a central nerve cell receives connections from blank neurons

100s-1000s

1

a central neuron can receive blank or blank input

excitatory, inhibitory

2

a single central neuron responds to different inputs, each mediated by a distinct transmitter called a blank

neurotransmitter

3

binding of neurotransmitter directly opens ion channel in this receptor

ionotropic

4

binding of transmitter indirectly regulates a channel by second messengers in this receptor

metabotropic

5

glutamate causes blank in the brain

excitation

6

gaba and glycine cause blank in the cns

inhibitory

7

when ipsp's shape the pattern of firing

sculpting

8

type 1 synaptic terminals

glutamatergic

9

type 2 synaptic terminals

gabaergic

10

there is a blank density of receptors in type 1 but not in type 2

high

11

type 1 synaptic terminal is more dendritic and synapses at blank of the neuron

spine

12

glutamate excitatory post synaptic current

central synapse

13

2 epsc

nmda, ampa

14

at resting membrane potential, blank block the pore of blank channels

magnesium, nmda

15

drug that blocks nmda receptors

apv

16

the currents seen with apv will be only blank because blank are blocked

ampa, nmda

17

current decay without nmda is much blank

slower

18

reversal potential is when the current is blank

0

19

when the trigger zone has a high density of blank channels, the threshold is blank

sodium, low

20

a dendrite has a blank action potential

back propagating

21

an axon has a blank action potential

forward propagating

22

strong depolarizing blank generates ap

epsp
