Relay Neuron - GCSE Psychology Definition

A relay neuron, also known as an interneuron, is a type of nerve cell that plays an important role in the communication process within the brain and spinal cord. It acts like a messenger between sensory neurons, which carry information from the body to the central nervous system, and motor neurons, which send signals from the central nervous system to muscles and glands. Relay neurons help process and interpret the information received from sensory neurons, ensuring that appropriate responses are triggered, such as moving your hand away from something hot. They are central to how we understand and respond to the world around us, making them a key topic in GCSE Psychology.
