The scarecrow needed it, Einstein had an excellent one, and it can store a whole lot of information. What is it you say? Why, the brain of course.
The brain is the control center of the body. Think of a telephone operator who answers incoming calls and directs them to where they need to go. Similarly, your brain acts as an operator by sending messages from all over the body to their proper destination.
The brain is one of the largest and most important organs of the human body. Weighing in at about three pounds, this organ has a wide range of responsibilities. From coordinating our movement to managing our emotions, the brain does it all.
The brain is made up of three main parts: the forebrain, the brainstem, and the hindbrain.
Forebrain
The forebrain is the most complex of the three parts. It gives us the ability to "feel," learn, and remember. It consists of two parts: the telencephalon (contains the cerebral cortex and corpus callosum) and the diencephalon (contains the thalamus and hypothalamus).The cerebral cortex allows us to understand the mounds of information we receive from all around us. The left and right regions of the cerebral cortex are separated by a thick band of tissue called the corpus callosum. The thalamus acts as a telephone line of sorts, allowing information to get through to the cerebral cortex. The hypothalamus is important for regulating hormones, hunger, thirst, and arousal.
