Zoom in close enough on a section of your brain and you would see a dense network of cells. The cells that create brain activity are called neurons, cells which carry an electrical signal from one to another.Neurons are the building blocks of the brain.
Each neuron connects with up to 100,000 neighbours in the worlds biggest cuddle! To the naked eye, neurons appear as the “grey matter” of the brain. A piece of brain the size of a pin head contains approximately 60,000 neurons.
