Synapse - GCSE Psychology Definition

A synapse is the tiny gap between two nerve cells, or neurons, in the brain and nervous system. It is where information is passed from one neuron to another. When a nerve signal reaches the end of a neuron, it triggers the release of chemicals called neurotransmitters. These chemicals cross the synapse and attach to special receptors on the next neuron, allowing the signal to continue on its path. Synapses are important because they help the brain to process information, manage thoughts, and control movements. Understanding synapses is important for GCSE Psychology as it explains how messages are transmitted in the brain.
