A neuron will generate an action potential if the inhibitory post-synaptic potential (IPSP) is greater than the excitatory post-synaptic potential (EPSP). Group of answer choices True False
Added by Loramae L.
Step 1
- IPSP (Inhibitory Post-Synaptic Potential) is a kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential. - EPSP (Excitatory Post-Synaptic Potential) is a kind of synaptic potential that makes a postsynaptic neuron Show more…

When an action potential occurs, it involves initially ions going into the axon, followed by ions leaving the axon. An action potential travels along the axon. Its speed is increased by its goal, which is to ultimately lead to the release of neurotransmitters. This release affects the next target neuron by producing an IPSP (which decreases the likelihood that the target neuron fires) or producing an EPSP (which increases the likelihood that the next neuron fires).
