| Surge in children accidentally eating marijuana-laced foods: Relaxed Colorado drug laws behind trend Posted: 27 May 2013 08:19 PM PDT A new study shows the relaxation of marijuana laws in Colorado may have caused the spike in the number of young children treated for accidentally eating marijuana-laced cookies, candies, brownies and beverages.  |
| Stem cell injections improve spinal injuries in rats Posted: 27 May 2013 08:18 PM PDT Scientists report that a single injection of human neural stem cells produced neuronal regeneration and improvement of function and mobility in rats impaired by an acute spinal cord injury.  |
| Meta-analysis: Bug and weed killers, solvents may increase risk of Parkinson's disease Posted: 27 May 2013 08:17 PM PDT A large analysis of more than 100 studies from around the world shows that exposure to pesticides, or bug and weed killers, and solvents is likely associated with a higher risk of developing Parkinson's disease.  |
| Scientists find mechanism that causes noise-induced tinnitus and drug that can prevent it Posted: 27 May 2013 12:37 PM PDT An epilepsy drug shows promise in an animal model at preventing tinnitus from developing after exposure to loud noise, according to a new study. The findings reveal for the first time the reason the chronic and sometimes debilitating condition occurs.  |
| Down syndrome neurons grown from stem cells show signature problems Posted: 27 May 2013 12:36 PM PDT Brain cells have been grown from skin cells of individuals with Down syndrome.  |
| Researchers identify genetic suspects in sporadic Lou Gehrig's disease Posted: 27 May 2013 07:06 AM PDT Researchers have identified mutations in several new genes that might be associated with the development of spontaneously occurring cases of the neurodegenerative disease known as amyotrophic lateral sclerosis, or ALS.  |
| Posted: 27 May 2013 07:06 AM PDT Humans and most mammals can determine the spatial origin of sounds with remarkable acuity. To accomplish this small daily miracle, the brain has developed a circuit that's rapid enough to detect the tiny lag that occurs between the moment the auditory information reaches one of our ears, and the moment it reaches the other. The mastermind of this circuit is the "Calyx of Held." Scientists have revealed the role that a certain protein plays in initiating the growth of these giant synapses.  |
| 'Should I stay or should I go?' Scientists link brain cell types to behavior Posted: 27 May 2013 07:06 AM PDT Neuroscientists have linked the activity of two types of brain nerve cells, neurons, to decisions made during particular type of behavior. They studied the activity of two types of inhibitory neurons in mice making decisions searching for food in a test area. They found distinct patterns of activity that marked when "stay" or to "go" foraging decisions were made.  |
| New gene discovery for babies born with hole in the heart Posted: 27 May 2013 07:05 AM PDT A new gene associated with a form of congenital heart disease in newborn babies – known as "a hole in the heart" has been discovered by researchers.  |
| Preterm birth affects ability to solve complex cognitive tasks: Too early to learn Posted: 27 May 2013 07:04 AM PDT Being born preterm goes hand in hand with an increased risk for neuro-cognitive deficits. Psychologists from the Ruhr-Universität Bochum and the University of Warwick, UK have investigated the relation between the duration of pregnancy and cognitive abilities under varying work load conditions.  |
