Every second, hundreds of billions of messages are exchanged between brain cells known as neurons. This neural activity generates enough electricity to light a low-wattage light bulb. Your brain will be able to charge a smartphone after 70 hours.
The brain also stores a lot of information. On average, it has the equivalent of 2.5 million gigabytes of digital memory.
The adult brain contains 100 billion neurons. Each of these brain cells is linked to approximately 10,000 other cells. Synapses are gaps in the network that allow neurons to communicate with one another. In total, there are approximately 100 trillion unique connections between neurons.
