Nerve conduction - Neural integration

Question 1

Activity of a neuron is determined by what?

Answer 1

The combined affects of all the excitatory and inhibitory influences on the neuron

• conducted by passive cable properties
• temporal and spatial summation

Question 2

What happens if summation reaches threshold?

Answer 2

Action potential will initiate at axon hillock

Question 3

Inhibitory and excitatory effects on a neuron do not equal what?

Answer 3

Inhibitory and excitatory effects on behavior

Question 4

What happens if a neuron’s function is to inhibit a behavior?

Answer 4

The effect of a inhibitory synaptic connection on that neuron is to decrease the inhibition of the behavior and increase the behavior

Question 5

What is the role of an autoreceptor?

Answer 5

receptors in the terminal button of the neuron that are sensitive to the nt the neuron releases. Activation causes decrease in nt production in and release from the neuron. If autoreceptors are not activated nt production and release in not inhibited and increases. Regulates the amount of nt.

Question 6

What do axioaxonic synapses influence?

Answer 6

The amount of NT released
