Which is the most likely outcome? ✓ [Choose ] Both interneurons fire action potentials The interneuron receiving both the EPSP and IPSP fires an action potential YES The interneuron receiving only the single EPSP fires an action potential Neither interneuron fires an action potential
Two separate post-synaptic interneurons receive synaptic potentials from afferent neurons in the periphery. The dendrites of one these interneurons receive an excitatory post-synaptic potential (EPSP) and an inhibitory post-synaptic potential (IPSP) of equal magnitude at the same time. The dendrites of the other interneuron receive one excitatory post-synaptic potential that is the same sized as the EPSP and IPSP received by the other interneuron

These are the types of Graded Potential.
EPSPs are excitatory signals which causes depolarisation of the membrane resulting in production of action potential.
IPSPs are inhibitory signals which causes hyperpolarisation of the membrane which causes unlikely to generate an action potential.
