As a neuroscientist, I am fascinated by the brain, small as it is (about 1.2 Kg), it happens to be the most complex and least understood organ in the universe. All your feelings, thoughts, memories, and actions are controlled by your brain.

In understanding how the brain works and how nerve cells communicate with each other, we begin to understand that the brain is responsible for a lot of the functions of the human body. The brain is a very sensory organ - it gets sensory input from the environment and prepares you for appropriate actions.
