Neurons, particularly those in the brain, receive multiple excitatory and inhibitory signals. What is the name of the extension of the neuron at which such signals are received? How does the neuron integrate these signals to determine whether or not to generate an action potential?
What kinds of changes in ion conductance may be expected in an action potential? And how do ion channels permit these changes?
