The Brain

Slide02

Every animal you can think of — mammals, birds, reptiles, fish, amphibians — has a brain. But the human brain is unique. Although it’s not the largest, it gives us the power to speak, imagine and problem solve. It is truly an amazing organ.

The human brain has been called the most complex object in the known universe, and in many ways it’s the final frontier of science. A hundred billion neurons, close to a quadrillion connections between them, and we don’t even fully understand a single cell.

The brain performs an incredible number of tasks including the following:

  • It controls body temperature, blood pressure, heart rate
  • It accepts a flood of information about the world around you from your various senses (seeing, hearing, smelling, tasting and touching).
  • It handles your physical movement when walking, talking, standing or sitting.
  • It lets you think, dream, reason and experience

All of these tasks are coordinated, controlled and regulated by an organ that is about the size of a small head of cauliflower.
