Local anesthetics work by preventing neurons from depolarizing, which blocks the transmission of pain signals. This is achieved by blocking sodium channels in the cell membrane, preventing the influx of sodium ions that depolarize the neuron. General anesthetics, on the other hand, typically work by increasing the hyperpolarization of neurons, making it harder for them to fire action potentials and reducing brain activity overall.
