LOS ANGELES (Jan. 16, 2013) – In a promising finding for epileptic patients suffering from persistent seizures known as status epilepticus, researchers reported today that new medication could help halt these devastating seizures. To do so, it would have to work directly to antagonize NMDA receptors, the predominant molecular device for controlling synaptic activity and memory function in the brain.

Philadelphia, Pa. (January 16, 2013) – With the rapidly expanding use of brain and spinal cord stimulation therapy (neuromodulation), new "remote presence" technologies may help to meet the demand for experts to perform stimulator programming, reports a study in the January issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.
Montreal, January 16, 2013 – Language mixing – using elements from two languages in the same sentence – is frequent among bilingual parents and could pose a challenge for vocabulary acquisition by one- and two-year-old children, according to a new study by Concordia University psychology professor Krista Byers-Heinlein. Those results are likely temporary, however, and are often counterbalanced by cognitive advantages afforded to children raised in a bilingual environment.
CAMBRIGDE, MA -- Epileptic seizures occur when neurons in the brain become excessively active. However, a new study from MIT neuroscientists suggests that some seizures may originate in non-neuronal cells known as glia, which were long believed to play a mere supporting role in brain function.
Charles Dickens' tales are filled with immortal characters — think of A Christmas Carol's Scrooge and Great Expectations' Miss Havisham. But more than whims of literary invention, his characters and plots often deal with the difficult social realities of Victorian England. His portrayal of the disabled — both in terms of medicine and the social discrimination they faced — is no exception.
PITTSBURGH—For the first time, scientists at Carnegie Mellon University's Center for Cognitive Brain Imaging (CCBI) have used a new combination of neural imaging methods to discover exactly how the human brain adapts to injury. The research, published in Cerebral Cortex, shows that when one brain area loses functionality, a "back-up" team of secondary brain areas immediately activates, replacing not only the unavailable area but also its confederates.
The amount of amyloid β (Aβ) in the brains of people with mild cognitive impairment (MCI) is contributing to early memory loss, and increases with severity of symptoms, finds a study in BioMed Central's open access journal Alzheimer's Research & Therapy. The non-invasive study which used 18F-florbetaben to find Aβ plaques in brain scans to also show that in MCI the affect of Aβ on memory loss is independent of other aspects of mental decline.
PHILADELPHIA – Brain diseases associated with the misformed protein tau, including Alzheimer's disease and frontotemporal lobar degeneration with tau pathologies, are characterized by neurofibrillary tangles (NFTs) comprised of pathological tau filaments. Tau tangles are also found in progressive supranuclear palsy, cortical basal degeneration and other related tauopathies, including chronic traumatic encephalopathy due to repetitive traumatic brain injuries sustained in sports or on the battle field.
Amsterdam, NL, January 15, 2013 – Approximately half a million individuals suffer strokes in the US each year, and about one in five develops some form of post-stroke aphasia, the partial or total loss of the ability to communicate. By comparing different types of aphasia, investigators have been able to gain new insights into the normal cognitive processes underlying language, as well as the potential response to interventions. Their findings are published alongside papers on hemispatial neglect and related disorders in the January, 2013 issue of.
AURORA, Colo. (Jan. 15, 2013) — Choline, an essential nutrient similar to the B vitamin and found in foods such as liver, muscle meats, fish, nuts and eggs, when given as a dietary supplement in the last two trimesters of pregnancy and in early infancy, is showing a lower rate of physiological schizophrenic risk factors in infants 33 days old. The study breaks new ground both in its potentially therapeutic findings and in its strategy to target markers of schizophrenia long before the illness itself actually appears.
CORVALLIS, Ore. – A new study has concluded that sports fans love to root for a hero and against a villain, but if the game is exciting, they'll enjoy it no matter who wins.
The research, recently published in the Journal of Media Psychology, examines emotional experiences, outcome satisfaction, and enjoyment of athletic events, particularly ones featuring individual athletes rather than team sports.
Quebec City, January 15, 2013—A team of researchers from Université Laval, CHU de Québec, and pharmaceutical firm GlaxoSmithKline (GSK) has discovered a way to stimulate the brain's natural defense mechanisms in people with Alzheimer's disease. This major breakthrough, details of which are presented today in an early online edition of the Proceedings of the National Academy of Sciences (PNAS), opens the door to the development of a treatment for Alzheimer's disease and a vaccine to prevent the illness.
Be it triumph or crushing defeat, exhilaration or agony, body language more accurately conveys intense emotions, according to recent research that challenges the predominance of facial expressions as an indicator of how a person feels.
Facebook posts resonate significantly more with human nature than books or even human faces, according to a new study by Laura Mickes and colleagues from the University of California San Diego in the US. The difference in memory between these microblogs and actual published words from a page is as striking as the difference in memory between amnesiacs and healthy controls. The work is published online in Springer's journal Memory & Cognition.
If this were a Facebook post, you would remember it – better than a stranger's face or a line from a published book.
That, in fewer than 140 characters, is the finding of research from the University of California, San Diego and the University of Warwick, published in the Springer journal Memory & Cognition.
Oh, and: The small, social-networking faux pas you were hoping would fade from your friends' memories real soon…? Don't count on it. Sorry. :/
