Picture of Brain. The brain is the complex organ responsible for processing sensory information (sound, touch, taste, sight, and smell). The brain controls voluntary and involuntary movements. Signals from the brain tell muscles to contract. Input from the brain controls the function of other organs in the body.
The largest region of the human brain, our cerebrum controls higher brain functions such as language, logic, reasoning, and creativity. The cerebrum surrounds the diencephalon and is located superior to the cerebellum and brainstem.
Last Updated: Mar 6, 2020 The brain is one of the most complex and magnificent organs in the human body. Our brain gives us awareness of ourselves and of our environment, processing a constant stream of sensory data. It controls our muscle movements, the secretions of our glands, and even our breathing and internal temperature.
