Web8 apr. 2024 · Neurones communicate with each other via electrical signals known as action potentials. They are brief changes in the voltage across the membrane due to the flow of certain ions into and out of the neurone. In this article, we will discuss how an action potential (AP) is generated and how its conduction occurs.
WebThe immensely elaborate process of modeling, remodeling, and maintenance of myelin occurs all over the brain simultaneously.
