SUMMARY
Nerve signals, specifically action potentials, are rapid changes in membrane potential that occur in neurons, facilitated by the myelin sheath which insulates axons and speeds up signal transmission. The discussion also touches on animal electricity, referencing Luigi Galvani's experiments that demonstrated the ability of electrical stimulation to induce muscle contractions in frogs. Understanding these concepts is crucial for grasping the fundamentals of neurophysiology and bioelectricity.
