Researchers discover significantly greater hippocampal atrophy in “born again” Protestants, Catholics and those who undergo “life changing” religious experiences.
Neuroscientist Patrik Verstreken, associated with VIB and KU Leuven, succeeded in undoing the effect of one of the genetic defects that leads to Parkinson’s using vitamin K2. His discovery gives hope to Parkinson’s patients. This research was done in collaboration with colleagues from Northern Illinois University (US) and will be published this evening on the website of the authorative journal Science.
Are We Relying Too Heavily On Computerized Testing To Determine If It Is Safe For A Football Player To Return To The Field After A Concussion?
Over the past few years, more emphasis has been placed on the dangers of concussions suffered by athletes participating in high impact sports, such as football. Highlighting the issue has lead to improvements in player safety via testing and minor rule changes to help insure player safety. However a recent study published in this months Journal of Clinical and Experimental Neuropsychology suggests many sports medicine practitioners are relying a little too heavily on computerized neuropsychological tests to determine whether a player is ready to go back into the action after a concussion.
In the largest study of brain development in preschoolers with autism to date, a study by UC Davis MIND Institute researchers has found that 3-year-old boys with regressive autism, but not early onset autism, have larger brains than their healthy counterparts.
A new study published in this months Journal of Neuroscience investigates the effect of early HIV infection on nerve cell and neuronal damage. Using a new mouse model, neuroscientist were able to examine the effects of early HIV infection within the nervous system. The study is the first to highlight neuronal loss during early stage HIV infection.
Researchers at UCLA have demonstrated how genetic variants rewire the brain in autistic patients. Examining the role of the CNTAP2 gene, which is believed to boost the risk of autism, researchers discovered a difference in connectivity between the left and right sides of the brain, depending on which version of the gene the patients carried. This research could provide a positive outcome in developing treatments for re-balancing the brain circuitry for autistic patients and promote a more normal neurological development.
Neuroscientists at the University of Copenhagen have developed a model which demonstrates how the brain releases dopamine. The model could provide a key insight into how the brain perceives punishment and reward. The researchers hope that their newly developed model could assist other scientists to better understand drug addiction and provide new treatments for schizophrenia.
New research suggests heavy alcohol use in teens can detrimentally affect neural development. Researchers have concluded that binge drinking can negatively disrupt normal developmental processes, leading to problems with learning and social adjustment in the long term. The study also discovered that increased use of alcohol can result in a decrease in attention and executive function. Additionally, increased marijuana use was discovered to decrease memory performance.
A new study released by researchers at Queen’s University investigates the cognitive effects of Parkinson’s disease. The study suggests that patients with Parkinson’s disease can perform a number of automated tasks better than those without the disease. However, patients with Parkinson’s disease have significant difficulty in switching between easy and hard tasks.
Researchers at Washington University have discovered a link between the brains cognitive control and motivation networks. The research could provide an insight into how people pursue goals and how motivation drives goal orientated behavior.
