What are the 3 types of the brain?
The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain. The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum (1). The hindbrain controls the body’s vital functions such as respiration and heart rate.

Brain Stem: lower part of brain, leads to spinal cord; the brain stem contains nerve fibers that carry signals to and from all parts of the body.
What are the two parts of brain?
The cerebrum, which forms the major portion of the brain, is divided into two major parts: the right and left cerebral hemispheres. The cerebrum is a term often used to describe the entire brain. A fissure or groove that separates the two hemispheres is called the great longitudinal fissure.
How old is the human brain?
521 million yearsFossilization of brain, or other soft tissue, is possible however, and scientists can infer that the first brain structure appeared at least 521 million years ago, with fossil brain tissue present in sites of exceptional preservation.
What part of the brain is behind the right eye?
The occipital lobe is the back part of the brain that is involved with vision.
