The brain....

The largest part of the human brain is the cerebrum, which is divided into two hemispheres. Underneath lies the brainstem, and behind that sits the cerebellum. The outermost layer of the cerebrum is the cerebral cortex, which consists of four lobes: the frontal, parietal, temporal and occipital.The cerebral cortex is greatly enlarged in human brains and is considered the seat of complex thought. Visual processing takes place in the occipital lobe, near the back of the skull. The temporal lobe processes sound and language, and includes the hippocampus and amygdala, which play roles in memory and emotion, respectively. The parietal lobe integrates input from different senses and is important for spatial orientation and navigation.

Why is the brain important?

The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human. Maintaining a healthy brain will help your mind stay clear and active, so that you can continue to work, rest and play.

How much is the brain used?

According to a survey from 2013, around 65 percent of Americans believe that we only use 10 percent of our brain. But this is just a myth, according to an interview with neurologist Barry Gordon in Scientific American. He explained that the majority of the brain is almost always active.
