The resting membrane potential for neuron A is -70m V, while the resting potential for neuron B is -50m V. The threshold voltage for the production of an action potential is -35mV for both neurons. Which of the following statements is incorrect?

• A. Neuron A must depolarise by 35mV to reach the threshold voltage.
• B. Neuron B must hyperpolarise by 15mV to reach the threshold voltage.
• C. The inside of bothneurons is negatively charged with respect to the outside.
• D. A single EPSP received by neuron A would cause it to depolarise slightly.
