EEG is an acronym for electroencephalography, which is an electrophysiological monitoring method to record electrical activity of the brain. It is typically noninvasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used in specific applications. Electroencephalography measures voltage fluctuations resulting from ionic current within the neurons of the brain. In clinical…

What Is The Occipital Lobe?
The occipital lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. The primary visual cortex is Brodmann area 17, commonly called V1 (visual one). Human…
The Four Basic Types of Multiple Sclerosis
Multiple sclerosis, or MS, is not a one size fits all disease. It affects each person who has it differently and therefore must be lumped in different categories in order to delineate the progression of the disease. Doctors have studied the disease and decided that there are four main types of MS. Some people will…
Mediterranean Diet in Alzheimer’s Patients Lengthens Lives
Research coming out of Columbia University Medical Center in New York indicates that following a “Mediterranean diet” could help people with Alzheimers disease live longer than patients who eat a more conventional Western diet. The study, published in the September 11, 2007, issue of Neurology, followed 192 people with Alzheimer’s disease in New York, an…
Magnetoencephalography New Tool for Diagnosing Alzheimers
Researchers at the University of Minnesota have announced a new noninvasive, painless method of diagnosing brain diseases. This is something we will be hearing a lot of in the future, because it represents new possibilities for less-stressful, pain free diagnosis for complex brain diseases such as Alzheimers, as well as a way to measure the…
Nueroprosthesis for Epileptic Seizures
Researchers at Purdue Universitys Weldon School of Biomedical Engineering have developed a miniature implanted device to detect epileptic seizures before they happen and prevent them. The work involves a minuscule transmitter, which is just three times the width of a human hair. The transmitter is designed to be implanted below the scalp in order to…
Final Stages of Parkinson’s
Parkinson’s disease can be a very devastating disorder. Not just for the people who experience it, but also for their relatives. It is a draining disorder that takes its course on a person, and when it is done, the person is typically reduced to a shell of himself. This can be a difficult thing to…
Headaches After Eating
Food is meant to be enjoyed. It tastes good and it’s enjoyable to eat, which is why so many people eat so much. However, sometimes the food isn’t as enjoyable as it should be because of the consequences of eating it. Some people suffer from headaches right after eating, which takes all the enjoyment out…
What Is Cerebrospinal Fluid?
Cerebrospinal fluid (CSF) is a clear, colorless body fluid found in the brain and spinal cord. It is produced in the choroid plexuses of the ventricles of the brain. It acts as a cushion or buffer for the brain, providing basic mechanical and immunological protection to the brain inside the skull. The CSF also serves…
