Your brain is linked to every part of your body by connectors called neurons or nerves. I studied the cranial nerves. There are 12 pairs of cranial nerves and each has a job to control speech, taste, hearing and many other body functions. The neurons are constantly sending signals to each other and forming connections with each other. Each neuron in the brain can be connected to thousands of others, and can receive over 100,000 signals every second.
