Neuron A is excitatory to neuron B. Describe three ways that the nervous system might prevent neuron B from experiencing an action potential
What will be an ideal response?
(1) Neuron A is not stimulated; therefore, it will not generate EPSPs on neuron B.
(2) Neuron A is actively inhibited by the formation of IPSPs on its dendrites and cell body; therefore, action potentials are not generated at A's axon hillock.
(3) Neuron A sends an impulse along its axon, but another neuron inhibits the release of neurotransmitter from A's axon terminal; this is presynaptic inhibition and no EPSPs are generated on B.
