Frontal lobe brain tumors can be cancerous or noncancerous. Both types of tumors can cause symptoms for a variety of reasons. Tumors can destroy brain cells, causing permanent brain damage and inflammation as well as placing pressure on tissues...
The cerebrum, which is the largest part of the brain, is divided into four areas, or lobes, each of which houses different functions. The cerebrum is also divided into two hemispheres: the left, which helps you think creatively and the right,...
The brain, an organ weighing approximately 3 pounds, initiates movement, interprets sensory input, provides intelligence and controls behavior. The cerebrum, found in the forebrain, is the largest and most highly developed part of the brain,...
The brain, the cranial portion of the central nervous system, is the center for control of all nerve and sensory activity in the body. The weight of the brain is about three lbs. Parts of the brain include the cerebrum, cerebellum, pons, medulla...
The cerebrum is the large upper area of the brain, which is physically divided at the midline into the right and left hemispheres. Within each hemisphere are five distinct regions, the insula, and the frontal, temporal, occipital and parietal...
The brain controls whether you laugh at a joke and takes sides when you have a disagreement with a coworker. When functioning normally, it tells your eyelids when to blink, remembers yesterday's news and calculates the cost of new shoes. Each...
The brain is divided vertically from front to back. While appearing like mirror images, there is some functional division between the lobes. These divisions are not absolute. In some people, the functions are reversed from side to side, while in...
Higher-order thinking skills distinguish humans from all other creatures. These skills include the capacity for comprehension and utilization of spoken and written language, as well as the executive functions. The executive functions encompass the...
Aphasia occurs after some parts of the brain responsible for language are damaged. In most cases, this damage involves the left side of the brain. This results in impairment in language production or understanding and can affect both written and...
Scientists have learned a lot about where and how brains process language by studying people who have lost their ability to produce or understand language after an accident or illness. Modern methods of neuroscience such as functional magnetic...
Creativity is the capacity to develop order through associations not previously recognized. The anatomy of creativity is that pattern of activation and suppression of communication pathways within the brain that allows for the emergence of novel...
Negative emotions, except anger, provoke withdrawal, say University of Valencia researchers in the March 2010 issue of "Hormones and Behavior." "The case of anger is unique because it is experienced as negative but, often, it evokes a motivation...
Laughter really is the best medicine. From pain and stress relief to improved immune system, heart and lung health, the evidence has become too overwhelming to ignore. One of the main reasons for this is because laughter stimulates your mind,...
Scientists divide the brain into three major parts: the cerebrum, the cerebellum and the brain stem, according to the Mayfield Clinic. They divide the cerebrum into four lobes: the frontal, parietal, temporal and occipital. Subdivisions of these...
There are many important parts of the external brain. The surface of the human brain consists of two main parts: the cerebrum and the cerebellum. The cerebrum has many specialized areas that are associated with high-order cognitive functioning...
The brain controls multiple bodily functions, ranging from simple to high-level tasks. Each part of the brain is responsible for separate duties, but they interact with each other through neural connections. The brain can be divided into three...
The cerebral cortex of the brain is divided into two hemispheres. The left hemisphere controls the right side of the body and is responsible for language and analytical thought. The right hemisphere controls the left side of the body and...
The left and right frontal lobe portions of the brain play a role in planning, evaluation, sequencing, visual analysis and language. A form of traumatic brain injury, a frontal lobe injury requires recuperative exercises that involve physical and...
In the U.S. alone, 795,000 people suffer from the consequences of a stroke each year, according to the American Heart Association. A stroke is a brief blockage of the blood stream to a particular brain region or a brain hemorrhage. Strokes in the...
The human brain, or encephalon, is composed of the forebrain, the midbrain and the hindbrain. The forebrain includes the cortex, the latest to appear in evolutionary development, and deeper structures. The cortex is responsible for the higher...
The human brain is the computer for the body. It is responsible for every function and movement, from breathing to scratching an itch on the nose. The brain can be labeled based on anatomy or function. In dealing with the anatomy of the brain,...
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...
While the various parts of the brain have been observed to have discreet functions for processing specific types of information, the process of thought, or cognition, uses a neural network of interconnections between separate areas. A region of...
Leg paralysis is a total loss of movement in one or both of the lower extremities because of injury or disease. The damage that is present is applied to the specific nerves that supply power to the leg muscles. Specifically, nerve damage resulting...
The brain is a very complex organ where every part is responsible for different activities. So when there is brain damage, normal brain function is affected. The brain is divided into three parts: the cerebrum, the cerebellum and the brain stem....
The temporal lobes are brain areas that sit behind the eye sockets and under the temple on each side. Seen from the side, the brain looks like a boxing glove with the thumb pointing in the direction of your gaze. Each temporal lobe is where the...
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 brain is an incredibly complex organ, responsible for managing everything from breathing and physical coordination to logic, language and artistic expression. While all animals have brains, they don't all possess the higher reasoning and...
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....
