excitation and inhibition

Question 1

what does an excitatory neurotransmitter increase when binded

Answer 1

positive charge in cell

Question 2

what is produced when excitatory neurotransmitter binds to post synaptic receptor

Answer 2

EPSP ( excitatory post synaptic potential )

Question 3

what does the EPSP mean for the neuron?

Answer 3

post-synaptic neuron is more likely to fire and pass on electrical impulse

Question 4

examples of electrical impulses in excitation

Answer 4

adrenaline/noradrenaline

Question 5

process of excitation

Answer 5

• excitatory neurotransmitter binds with post synaptic receptor increasing positive charge in cell
• results in EPSP
• post synaptic neuron more likely to fire and pass on electrical impulse

Question 6

what does an inhibitory neurotransmitter increase?

Answer 6

negative charge of post synaptic neuron

Question 7

what is produced when an inhibitory neurotransmitter binds to a post synaptic neuron?

Answer 7

IPSP ( inhibitory post synaptic potential )

Question 8

what does the IPSP result in?

Answer 8

less likely that the postsynaptic neuron is likely to fire and pass on electrical impulse

Question 9

inhibitory process

Answer 9

• inhibitory neurotransmitter binds to post synaptic receptor increasing negative charge of post synaptic neuron
• results in IPSP
• making less likely for eletrical impulse to fire and pass at post synaptic neuron

Question 10

example of inhibitory electrical impulse

Answer 10

serotonin/ GABA

Question 11

what is summation

Answer 11

excitatory and inhibitory effects of neurotransmitters are summed up to determine whether or not cell fires

Question 12

summary of summation

Answer 12

• during synaptic transmission, more than one type of neurotransmitter will diffuse across synaptic cleft- inhibitory or excitatory
• whether post-synaptic neuron fires decided by summation
• most prominent (inhibitory or excitatory) will create the potential (IPSP or EPSP)
