Regarding the electrical activity of neurons, which of the following is?

A. Neurons are integrators; they can have a vast number of different inputs, but they produce just a single output signal, which they transmit to their targets
B. There is a small voltage difference between the inside and the outside of the neuron in it resting state, known as the action potential
C. The inputs to neurons are tiny amounts of chemical neurotransmitters
D. In the steady state neurons, there is an active pumping of ions across the neuronal membrane
