According to One Life, much of our early study of the brain came from careful examination of the structure of the brain of diseased patients. Early brain studies looked at the gross anatomy of the brain and then cut into the brain (a process known...
About 2 million years ago, a human brain was half the size of today's human brain. Your brain controls everything about you: breathing, thought, movement and interaction with others. Animals have brains that look similar to the human brain in most...
The human brain acts like "a powerful computer" that controls how people move, think and react, according to the Science Kids website explains. To protect this vital organ, more than 20 bones join together to create a protective covering called...
The human brain is an extremely complex organ which, among many other things, controls blood pressure and heart rate, interprets the senses, initiates body movement, and is the home of emotions and intelligence. The adult human brain weighs about...
The human brain is part of the central nervous system. The brain is protected by the skull on the outside and meninges, a three-layer membrane, on the inside. The average weight of an adult brain is about 3 lbs. An interruption in blood flow to...
The brain is an amazing organ that weighs about 3 lbs. and is encased in a protective layer of bone called the skull. The brain is the central feature of the human body, and adds dimensions such as personality and emotions to life as well as...
Many different things can affect brain function, from infection, to trauma, to metabolic imbalances, but only a few of them are deadly. Most of these deadly diseases are equal opportunity, infecting just as many people from First World countries...
The human brain is a complex organ and is responsible for relaying information to the other parts of the body. For example, the brain is involved in memory, thinking, voluntary and involuntary movements. Multiple components make up the human...
The human brain is a fascinating and complex organ, capable of not only running your body's essential systems, but also producing intricate memories and the ability to engage in abstract thought. The human brain has a gelatinous consistency, and...
The human brain regulates most organ function and is responsible for thought, memory, speech and movement, according to MedlinePlus. There are a number of different conditions that can affect the brain; they can be genetic or acquired, and have...
The human brain is an extremely complex organ that functions as the control center of the entire body. According to National Geographic, the human brain weighs approximately three pounds. The brain is one of the body's largest organs and...
The human brain weighs about 3 lbs. and contains 100 billion neurons and even more glial cells, according to Neuroscience For Kids, a University of Washington website. The brain has three major divisions, which contain different structures and two...
The human brain controls how we interpret and integrate everything that is going on around and inside of us. The brain is divided into various sections with their own functions.
The brain is an active muscle that you engage during every activity and thought process. As you age, you may notice that your brain isn't quite as resilient or responsive as it used to be. Performing exercises for your brain can help strengthen...
The human brain weighs between 1.3 and 1.4 kilograms and has 100 billion neurons, which are the cells in the brain that transmit electrical signals. But neurons are not the only cells found in the brain. The other groups of cells, the glial cells,...
The brain is an amazing organ. It is responsible for everything we think, see and do. The different components interact like a precision machine, processing and sending signals with the efficiency of a powerful computer. The billions of neurons...
The cerebrum, which is the largest part of the brain, is divided into two hemispheres--the left hemisphere and right hemisphere. Each hemisphere has all four lobes of the brain--frontal lobe, parietal lobe, temporal lobe and occipital lobe--but...
The human brain is far more than gray mass taking up space in your skull. The cerebral cortex, brain stem and cerebellum make up the parts of the brain. These parts function individually, yet work together and make it possible for you to do all...
Your brain receives information from the rest of your body in the form of electrical signals. The brain then integrates the information and generates electrical signals of its own, sending directions that allow you to move, react, think and learn....
When faced with a menacing threat, your brain's stress response system harnesses your body's energy resources in order to help you get out of harm's way. In the short-term, this response keeps you safe. If, however, your stress response system is...
You probably know that high cholesterol can clog your arteries. Persistently high cholesterol can also prevent your brain from working properly and raise the risk of developing neurological diseases such as Alzheimer's. Every cell in your body is...
The phrase, "I think therefore I am," written by Rene Descartes in 1637, expressed the philosophy at that time in history. According to "Memory: From Mind to Molecules," the statement proved to be incorrect from biological studies in the 20th...
Explaining the human brain to your child may seem overwhelming, but it can be a fun way to introduce your child to science and biology. The human brain is best understood by breaking it down into manageable sections and through the use of visual...
The human brain is a complex conglomerate of brain matter, nerves and blood vessels that control your ability to walk, talk and think. Though the human brain may appear to be one large mass of tissue, it's actually made up of numerous different...
The human brain consists of more than 100 billion brain cells and weighs about 3 pounds by adulthood. The organization and size of the brain reflect its function. For example, the largest part of the brain is the cerebral cortex, responsible for...
The brain, sitting atop the spinal column, controls everything a person does, whether the functions classify as voluntary, such as standing up or running, or involuntary such as breathing and having a heartbeat. The brain itself consists of...
The human brain can be anatomically divided into three main sections, or layers. The outermost part is called the forebrain (the prosencephalon); the middle layer is called the midbrain (the messancephalon); and the innermost part of the brain is...
Without having to think about it, your brain keeps everything in your body working properly. To enhance your brain function, you should eat various foods to keep your brain fueled with valuable nutrition. Taking time to add brain-healthy foods to...
