  • Q:

    In a laboratory, a plate of neurons is constructed composed with half of the neurons having a threshold potential of -50 mV and the other half with a threshold potential of -30 mV. Both types of neurons have a resting potential of -70 mV. 50 mV of voltage are applied uniformly across these plated neurons. Which of the following would be expected?

     

    A

    0% of the neurons would fire

    B

    50% of the neurons would fire

    C

    100% of the neurons would fire

    D

    the percentage of neurons that would fire cannot be determined
