A stroke occurs when oxygen is restricted to a portion of the brain for enough time to cause damage. This may be due to a blood clot or blockage in one of the brain's blood vessels, or a burst blood vessel in the brain. When damage occurs in the...
An occipital stroke occurs when the occipital lobes of the brain are damaged due to a lack of oxygenated blood. A stroke is often caused by problems with blood flow in the brain, such as a blocked artery or an artery that has burst. Damage to the...
Epilepsy is a neurological disease stemming from a deregulation of brain signaling. Nerve cells within the brain, called neurons, commonly communicate with each other through cell junctions called synapses. One nerve cell sends a chemical signal...
The cerebrum houses the four major brain regions responsible for higher functioning. According to the Center for Neuro Skills, these four regions include the frontal lobes, parietal lobe, occipital lobe and the temporal lobe. The cerebrum is also...
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...
Each part of the human brain is responsible for functions in the body. The brain is made up of three major sections: the cerebrum, the cerebellum and the brain stem. The cerebrum is divided into two parts, the left hemisphere and the right...
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 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 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...
In "The Cognitive Neurosciences III", there are over 1000 pages devoted to explaining the relationship between mind and brain. At the most general level, human cognitive processing occurs in the cortex, the outer layer of the brain composed of...
According to the National Institute of Neurological Disorders and Stroke (NINDS), the brain is the most complex part of the human body. The brain is responsible for bodily functions and converting sensory information into motor reactions. The...
Epilepsy is a neurological disorder characterized by regular seizures that can affect all or part of the brain. Normal signal transmission between nerve cells in the brain involves a short electrical pulse, which activates and signals to a...
Brain tumors can affect the optic nerve itself and the cranial nerves that control eye movement. Tumors in different parts of the brain affect different nerves and often affect several nerves at once. According to "Adams and Victor's Principles of...
The central nervous system, which consists of the brain, spinal cord and nerves, controls every function in the body. The brain is divided into three parts: the forebrain, the midbrain and the hindbrain, each of which is further divided into...
The human brain is part of the body’s central nervous system; in conjunction with the spinal cord and nerves, it controls everything that the body does. The main functions of the brain are controlled by three of the brain structures: the...
The brain consists of different regions that have distinct functions but communicate with each other. The brain consists of the cerebral cortex, brain stem and cerebellum. The cerebral cortex is further broken down into four lobes: the frontal,...
Calcium deposits on the brain -- also known as cranial calcification -- occur when a medical disorder causes your body to deposit calcium in your brain rather than in teeth or bones. Calcium deposits in the brain can cause changes in brain...
The human brain is responsible for overseeing an entire network of nerves that relay messages throughout the body, regulating every aspect of its activity. Our brains are complex and have evolved specialized structures to handle particular types...
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...
The human brain contains five major divisions--the cerebral cortex, cerebellum, thalamus, midbrain and brain stem--each with a specific region and function. These regions are interconnected to allow information to travel from one region to...
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...
The brain consists of three functional regions, which developed at differing times over the course of human evolution. The newest and most complex area of the brain is the forebrain, which consists of the cerebrum and its underlying support...
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...
Physicians grade brain tumors according to their degree of malignancy. One aspect of a tumor's appearance that affects its grade is whether it is diffuse--with no clear edge or margin--or focal--with a clear margin defining where it begins and...
The brain and spinal cord make up the central nervous system. They process information presented by sensory receptors located all over the body and execute appropriate responses. Different regions of the brain are responsible for integrating...
Brain tumors occur in various places within the cranium or skull. Many benign tumors can threaten life but in a different way than the malignant ones. Because a tumor occupies space, it infringes on what little space the brain has within the...
Your baby will use her brain for thinking, crawling, walking, eating, laughing and speaking. According to PBS, at just 4 weeks gestation, your unborn baby's brain cells are forming at a rate of 250,000 per minute. These cells will link together...
The brain is divided into three main parts: the cerebrum, cerebellum and brainstem. Each part has a specific location and contains certain divisions. Within each part, there are nerve cells that give the tissue either a gray or white appearance...
The brain is a complex structure that is composed of different structures and tissues. According to the National Institutes of Neurological Disorders and Stroke (NINDS), the brain has three major parts: prosencephalon, mesencephalon and...
