Introducing the Neuron
Neurons are specialized cells that transmit chemical and electrical signals to facilitate communication between the brain and the body.
Stages of the Action Potential
Neural impulses occur when a stimulus depolarizes a cell membrane, prompting an action potential which sends an "all or nothing" signal.
Mechanics of the Action Potential
The synapse is the site at which a chemical or electrical exchange occurs between the presynaptic and postsynaptic cells.
Neurotransmitters
Neurotransmitters are chemicals that transmit signals from a neuron across a synapse to a target cell.
Neural Networks
Neural networks consist of a series of interconnected neurons, and serve as the interface for neurons to communicate with each other.
