History of Neuroscience Beginner Ancient Egypt and the Edwin Smith Papyrus The oldest known written description of the brain comes from an Egyptian surgical text copied around 1600 BCE — a practical trauma manual that noticed head injuries could paralyse the body. August 31, 2026 · 2 min read

History of Neuroscience Beginner Vesalius, Willis and the Renaissance Brain Andreas Vesalius corrected Galen by looking for himself; Thomas Willis turned attention from the ventricles to the brain tissue itself and coined the word 'neurology'. August 27, 2026 · 2 min read

History of Neuroscience Intermediate Soups and Sparks: The Discovery of Chemical Transmission Otto Loewi's dream experiment with two frog hearts proved that nerves talk with chemicals — and set off a decades-long 'war of the soups and the sparks'. August 23, 2026 · 2 min read

History of Neuroscience Beginner The Birth of Modern Neuroscience From the founding of the Society for Neuroscience in 1969 through the 'Decade of the Brain', brain imaging, genetics and the BRAIN Initiative: how neuroscience became one of science's biggest fields. July 24, 2026 · 2 min read

History of Neuroscience Intermediate Sherrington and the Synapse Charles Sherrington named the synapse in 1897, showed that reflexes integrate excitation and inhibition, and gave neuroscience the idea of the nervous system as an integrator. June 18, 2026 · 2 min read

History of Neuroscience Advanced Hodgkin, Huxley and the Squid Giant Axon Using a nerve fibre half a millimetre wide and a clever circuit called the voltage clamp, Alan Hodgkin and Andrew Huxley worked out exactly how the action potential is made — and wrote it down as equations still used today.

History of Neuroscience Beginner Broca, Wernicke and the Language Areas A patient who could only say 'tan', and another who spoke fluently but made no sense: how two 19th-century neurologists discovered that language lives largely in the left hemisphere. May 17, 2026 · 3 min read

History of Neuroscience Beginner Medieval and Islamic Brain Science From the 'cell doctrine' that housed imagination, reason and memory in the brain's ventricles to Ibn al-Haytham's optics and Ibn Sina's medicine — how ideas about the brain were preserved and extended between antiquity and the Renaissance.

History of Neuroscience Intermediate Hubel, Wiesel and the Visual Cortex A slide jammed in a projector revealed that neurons in the visual cortex respond to edges at particular angles — and opened up how the brain builds vision piece by piece. April 28, 2026 · 2 min read

History of Neuroscience Beginner Greek and Roman Ideas About the Brain Alcmaeon put the mind in the head, Hippocrates called epilepsy a brain disorder, Aristotle bet on the heart, Alexandrian anatomists traced the nerves, and Galen proved it with pigs. March 15, 2026 · 2 min read

History of Neuroscience Intermediate Descartes and the Mechanical Reflex René Descartes pictured the body as a machine of tubes and valves, sketched the first reflex, put the soul in the pineal gland — and left neuroscience the mind-body problem. February 3, 2026 · 2 min read

History of Neuroscience Beginner Patient H.M. and the Science of Memory Henry Molaison lost the ability to form new memories after brain surgery in 1953 — and over five decades of testing taught science that memory is not one thing and depends on the hippocampus. January 27, 2026 · 2 min read

History of Neuroscience Intermediate Golgi, Cajal and the Neuron Doctrine A silver stain that blackened one cell in a hundred settled the most important question in neuroscience: is the nervous system one continuous web, or made of separate cells? January 17, 2026 · 3 min read

History of Neuroscience Beginner Phineas Gage In 1848 an iron rod blasted through a railway foreman's head. He survived — but 'was no longer Gage'. The most famous case in neuroscience, and how its story grew in the telling. January 7, 2026 · 2 min read

History of Neuroscience Beginner Galvani and Animal Electricity Twitching frog legs in 18th-century Bologna revealed that nerves and muscles run on electricity — sparking a feud that gave us the battery and, eventually, the action potential. December 2, 2025 · 2 min read

History of Neuroscience Beginner Phrenology and the Localization Debate Bumps on the skull, ablated pigeons and electrified dog brains: how the 19th century argued over whether different parts of the brain do different jobs. November 30, 2025 · 2 min read

About this project

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.
