Brain Cell

Cuddly soft toy.

FACTS: The little grey cells that make up your mind are primarily neurons. You have approximately 100 billion of them in your head!

The typical neuron is connected to thousands of others forming an inconceivably dense signal-processing network. With over 1,000 trillion connections or synapses, in your brain, there are more transmission pathways in your head than there are atoms in the universe. But before you let that go to your head, think about this: the number of synapses peaks in early childhood, so the average three-year-old has ten times as many as the average adult!
