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
