UCSF scientists controlled seizures in epileptic mice with a one-time transplantation of medial ganglionic eminence (MGE) cells, which inhibit signaling in overactive nerve circuits, into the hippocampus, a brain region associated with seizures, as well as with learning and memory. Other researchers had previously used different cell types in rodent cell transplantation experiments and failed to stop seizures. http://medicalxpress.com/news/2013-05-epilepsy-mice-brain-cells.html Neuroscience Sun, 05 May 2013 13:00:27 EST news286953942 New research suggests that fainting may be genetic and, in some families, only one gene may be responsible. However, a predisposition to certain triggers, such as emotional distress or the sight of blood, may not be inherited. The study is published in the April 16, 2013, print issue of Neurology. Fainting, also called vasovagal syncope, is a brief loss of consciousness when your body reacts to certain triggers. It affects at least one out of four people. http://medicalxpress.com/news/2013-04-fainting-families-triggers.html Neuroscience Mon, 15 Apr 2013 16:00:01 EST news285245041 Brain imaging soon after mild traumatic brain injury (mTBI) or mild concussion can detect tiny lesions that may eventually provide a target for treating people with mTBI, according to a study released today and that will be presented at the American Academy of Neurology's 65th Annual Meeting in San Diego, March 16 to 23, 2013. http://medicalxpress.com/news/2013-03-brain-imaging-mild-injuryconcussion-lesions.html Neuroscience Tue, 12 Mar 2013 16:00:05 EST news282319048 A single concussion may cause lasting structural damage to the brain, according to a new study published online in the journal Radiology. http://medicalxpress.com/news/2013-03-concussion-brain.html Diseases, Conditions, Syndromes Tue, 12 Mar 2013 05:17:04 EST news282284216 Since the mid-1800s, doctors have used drugs to induce general anesthesia in patients undergoing surgery.

The researchers sought to identify risk factors for prolonged concussion symptoms by examining a large national database of high school athletes' injuries. Previous concussion studies were limited in scope, focusing only on male football players. The information from this study applies to male and female athletes from a number of different sports. http://medicalxpress.com/news/2013-01-factors-prolonged-sports-concussion-symptoms.html Health Wed, 16 Jan 2013 16:17:48 EST news277575460 A new mobile 'app', downloadable free of charge, will assist with the training of future neurosurgeons, and is just one of a stream of programmes being developed, adapting visual computing and three dimensional realities to provide cost-effective virtual learning for a range of medical procedures. http://medicalxpress.com/news/2013-01-virtual-ipad-app-future-neurosurgeons.html Surgery Wed, 09 Jan 2013 09:23:13 EST news276945779 (HealthDay)—Older adults with a history of traumatic brain injury (TBI) with loss of consciousness (LOC) have a 2.5- to almost four-fold higher risk of subsequent re-injury later in life, according to research published online Nov. 21 in the Journal of Neurology, Neurosurgery & Psychiatry. http://medicalxpress.com/news/2013-01-prior-brain-injury-linked-re-injury.html Neuroscience Thu, 03 Jan 2013 14:20:01 EST news276442508 Using a special magnetic resonance imaging (MRI) technique to image patients with mild traumatic brain injury (MTBI), researchers have identified a biomarker that may predict which patients will do well over the long term, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). http://medicalxpress.com/news/2012-11-imaging-brains-compensate-traumatic-injury.html Neuroscience Mon, 26 Nov 2012 00:00:03 EST news273068843 MRI shows changes in the brains of people with post-concussion syndrome (PCS), according to a new study published online in the journal Radiology.
