Today, techniques are available to study small neurons and even minute areas of their membranes. Individual neurons can vary in shape enormously, but they all have similar characteristics - a receptive zone, a process center, and a conductive zone. In this presentation, animation details the mechanisms controlling the operation of our nerves. Coverage includes the formation and propagation of Action Potentials, the action of voltage activate and ligand gated ion channels, the transmission of nerve signals across synapses, and the role of transmitters, agonists, antagonists, and second messengers. The rapid growth in basic research on the central nervous system has aided in the search for new drugs to treat nervous disorders such as Alzheimer's, Parkinson's Disease, stroke prevention, depression and anxiety. Micro electrode techniques used in studying brain slices and patch clamp techniques used in studying single neurons are both demonstrated.
