Neuron - GCSE Psychology Definition

A neuron is a special type of cell in the brain and nervous system that helps send and receive information. It works a bit like a tiny messenger that carries electrical signals and chemical messages throughout the body, allowing us to think, feel, move, and respond to the world around us.

Neurons communicate with each other by sending these messages across small gaps called synapses. They are incredibly important for everything our body does, from simple actions like moving our hands to complex tasks like solving a difficult maths problem.

Understanding how neurons work helps psychologists learn more about how our brains control our behaviour and mental processes.
