Step 1
An EPSP is a temporary increase in the postsynaptic membrane potential that makes the neuron more likely to fire an action potential. This typically involves a depolarization of the membrane. Show more…

9. Assume that a single IPSP has a negative magnitude of -0.5 mV at the axon hillock and that a single EPSP has a positive magnitude of +0.5 mV. For a neuron with an initial membrane potential of -70 mV, the net effect of the simultaneous arrival of six IPSPs and two EPSPs would be to move the membrane potential to A. -72 mV B. -68 mV C. -71 mV D. -70 mV

Assume that a single IPSP (inhibitory postsynaptic potential) has a negative magnitude of -0.5mV at the axon hillock, and that a single EPSP (excitatory postsynaptic potential) has a positive magnitude of + 0.5mV. For a neuron with an initial membrane potential of -70mV, the net effect of the simultaneous arrival of six IPSPs and two EPSPs would be to move the membrane potential to: Select one: a. -71 mV b. -70 mV c. -68 mV d. -69 mV e. -72 mV
