Question

question 11 for a neuron to generate an action potential, which of the following must be true? the neuron must be in the refractory period. glial cells must release neurotransmitters into the axon. dopamine and serotonin must be present in equal amounts. excitatory impulses must outnumber inhibitory impulses. 5 pts

Explanation:

An action potential in a neuron is generated when the sum of excitatory postsynaptic potentials (EPSPs) over - comes the sum of inhibitory postsynaptic potentials (IPSPs). Glial cells do not release neurotransmitters into the axon for action - potential generation. Dopamine and serotonin are not required to be present in equal amounts for an action potential. A neuron cannot generate an action potential during the refractory period. So, excitatory impulses must outnumber inhibitory impulses for an action potential to occur.

Answer:

Excitatory impulses must outnumber inhibitory impulses.
