This being said, there are over 86 billion neurons in the brain. For example, when a certain set of neurons in the brain fire, the right index finger will twitch. When a stimulus is strong enough, it causes an action potential which fires the neuron and its consequential function ensues. Neurons function through stimulation and generation of electrical impulses called action potentials.Īction potentials are an all-or-nothing response. Neurons are responsible for our senses (detecting touch, pain, smells, tastes, sight, etc.), motor skills, and overall relay of information for comprehension and processing. Neurons have branches called axons which can transmit information, when stimulated, to and from other neurons in a matter of microseconds. Within the brain, we have billions of specialized informational transmitting cells called neurons. Migraines are a phenomenon isolated to the brain. What on earth just happened?
