In neuroscience, depolarization is an "all or nothing" response; what does that mean?
The neuron's intracellular charge must get more negative to meet a certain
threshhold in order to depolarize. If the neuron does not hit that threshold, then the
neuron will not fire

The neuron will either accept all signals, or none of the signals received. If the
neuron is ready to receive signals, then it automatically depolarizes and sends the
signals to the next neuron.

The neuron's intracellular charge must get more positive to meet a certain
threshhold in order to depolarize. If the neuron does not hit that threshold, then the
neuron will not fire

The neuron decides how much of the electochemical signals to send to the next
neuron; all or nothing
