neurons

A withdrawal reflex pulls your hand off a hot pan before you consciously feel pain. The brain alone holds about 86 billion neurons, and the fastest nerve fibres carry signals at up to 120 metres per second. Here is how it all works.

The brain runs on roughly 86 billion neurons, consumes 20% of your body's energy despite weighing only 2% of your body, and rewires itself with every new experience. Here is the mechanism behind all of it.

86 billion neurons, trillions of synapses, about 20% of your resting energy. How the human brain actually processes information, and where the computer analogy breaks.

Neurons, action potentials, brain regions, plasticity, and the science behind consciousness — a clear neuroscience primer.

How Ramón y Cajal's microscopy revealed neurons as individual cells composing the nervous system

Neural networks are loosely inspired by the brain — but they're really just stacks of math doing pattern recognition. Here's how they work, why they're so powerful, and what's actually going on inside.

Your brain has 86 billion neurons firing at 1,000 trillion connection points. Here's a tour of how it actually generates everything you think, feel, and remember.
