Assume That a Single IPSP Has a Negative Magnitude of -0.5

question 42

Multiple Choice

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) -71 mV.
• C) -70 mV.
• D) -69 mV.
• E) -68 mV.
