Big Picture: Inside the Brain poster

Our brains contain some 86 billion neurons, or nerve cells, which communicate via junctions called synapses. At these junctions, neurons are just 20 nm apart. Inside each of our heads you'll find one brain, billions of neurons and trillions of synapses. We've shown one of each in detail in our free 'Inside the Brain' poster. Download the poster, download the poster images or order a full-sized hard copy below.
