NeuroScience Decoded is an independent, plain-language encyclopedia of the brain and nervous system. It covers what neuroscience is, five thousand years of its history and the people who made it, how neurons and synapses work, brain chemistry and anatomy, development, the senses, movement, memory, emotion, sleep and consciousness, neurological and mental health conditions, the tools scientists use, the overlap with artificial intelligence, treatments, and the ethics and future of the field.

Every entry is written to be understood by a curious reader with no science background. Each one is tagged Beginner, Intermediate or Advanced, opens with an In plain English summary, offers everyday analogies and try-it-yourself examples, ends with key takeaways, and links to the concepts worth reading first.

Where the science is unsettled — adult neurogenesis, the glymphatic system, theories of consciousness, mirror neurons — the site says so and explains the competing views rather than picking a winner. Facts and recent developments were checked before publication.
