States of unconsciousness, such as those that occur during sleep or while under the effect of anesthesia, have been the focus of countless past neuroscience studies. While these works have identified some brain regions that ...
(Medical Xpress)—Whooping cough (Pertussis) is a highly contagious disease caused by the bacterium Bordetella pertussis and characterized by attacks of severe coughing, often (but not always) with a characteristic high-pitched ...
Scientists at the Gladstone Institutes have deciphered how a protein called Arc regulates the activity of neurons—providing much-needed clues into the brain's ability to form long-lasting memories. These findings, reported ...

(Medical Xpress)—The smooth operation of the brain requires a certain robustness to fluctuations in its home within the body. At the same time, its extraordinary power derives from an activity structure poised at criticality. ...
Researchers funded by the National Institutes of Health have developed a flexible brain implant that could one day be used to treat epileptic seizures. In animal studies, the researchers used the device – a type of electrode ...

An epileptic seizure is a transient symptom of excessive or synchronous neuronal activity in the brain. It can manifest as an alteration in mental state, tonic or clonic movements, convulsions, and various other psychic symptoms (such as déjà vu or jamais vu). The medical syndrome of recurrent, unprovoked seizures is termed epilepsy, but seizures can occur in people who do not have epilepsy.
About 4% of people will have an unprovoked seizure by the age of 80 and only 30% to 40% or according to another study 50% chance of a second one. Treatment may reduce the chance of a second one by as much as half.
The treatment of epilepsy is a subspecialty of neurology; the study of seizures is part of neuroscience. Doctors who specialize in epilepsy are epileptologists; doctors who specialize in the treatment of children with epilepsy are pediatric epileptologists.
