The all-or-nothing principle states that a neuron either fires completely or does not fire at all. Once an electrical impulse reaches a certain threshold, it will fire down the axon without losing any intensity. The depolarizing principle is not a commonly used term in neuroscience. The permeability principle refers to the ability of ions to pass through a cell membrane. The nature-nurture principle refers to the interaction between genetic and environmental factors in determining behavior and traits.
