Mild cooling of the brain after a head injury prevents the later development of epileptic seizures, according to an animal study reported this month in the Annals of Neurology.
Epilepsy can result from genetics or brain damage. Traumatic head injury is the leading cause of acquired epilepsy in young adults. It is often difficult to manage with antiepileptic drugs. The mechanisms behind the onset of epileptic seizures after brain injury are not known . There is currently no treatment to cure it, prevent it, or even limit its severity. (more…)
At the level of proteins, organisms can adapt by editing their RNA — and an editor can even edit itself. Brown University scientists working with fruit flies found that “locking down” the self-editing process at two extremes created some strange behaviors. They also found that the process is significantly affected by temperature.
PROVIDENCE, R.I. [Brown University] — Because a function of RNA is to be translated as the genetic instructions for the protein-making machinery of cells, RNA editing is the body’s way of fine-tuning the proteins it produces, allowing us to adapt. The enzyme ADAR, which does this editing job in the nervous system of creatures ranging from mice to men, even edits itself. In a new study that examined the self-editing process and locked it down at two extremes in fruit flies, Brown University scientists found some surprising insights into how this “fine-tuning of the fine-tuner” happens, including bizarre behavioral effects that come about when the self-editor can’t edit.

Most patients wait until it’s too late to prevent serious disability
While the thought of any type of surgery can be disconcerting, the thought of brain surgery can be downright frightening. But for people with a particular form of epilepsy, surgical intervention can literally be life-restoring.(more…)
EAST LANSING, Mich. — New guidelines from the American Academy of Neurology will help physicians better choose seizure drugs for people on HIV/AIDS medication, avoiding deadly drug interactions and preventing critical anti-HIV drugs from becoming less effective, possibly leading to a more virulent strain of the disease.
Michigan State University’s Gretchen Birbeck – who spends several months each year in the sub-Sahara African nation of Zambia researching epilepsy, HIV /AIDS and cerebral malaria – is the lead author of the medical guideline, which was co-developed with the World Health Organization through the International League Against Epilepsy.

Until now it was believed that a person is unable to read the thoughts of fellow human beings. “Spying” on the dreams of another person appeared unrealistic. However, recent research by American scientists revealed that both these things are quite possible. Overly complex devices and paranormal abilities are not required to do so.
Recently, a respectable scientific journal Nature published an article that ten years ago would have been considered a fiction and would not have been publication at all. A group of American researchers led by Dr. Moran Cerf claims to have found a way to electronically records and decipher human dreams and thoughts. No complicated devices are required. The entire transcript can successfully go through an electroencephalograph – a device that for decades has been used by neuroscientists around the world. (more…)
