When you've finished watching the video, come back to the test and answer the following questions:A neuron at rest reads -70 mV with a threshold level of -60 mV. Given the following graded potentials along the dendrites, what is MOST likely to occur in the neuron? Input a -5 mV; input b +6 mV; input c +3 mV; input d +2 mV; input e -3mV
A. The voltage will reach threshold and an action potential will occur.
B. Inhibition will occur where the voltage will drop below resting potential.
C. The voltage will slightly depolarize, but not enough to reach threshold.
D. The neuron will maintain -70mV.
