Gated ion channels in the neuronal membrane open and close in response to specific stimuli, such as changes in voltage, ligand binding, or mechanical forces, making them not always open or closed. They are also specific to which ions can pass through them, allowing for selective ion permeability that is crucial for generating action potentials and other cellular signals.
