Signal variability, cognitive performance in the aging human brain As we age, the physical make up of our brains changes. This includes changes in neural processing in grey matter, but also in the deterioration of structural connections in the brain, which allow communication between distinct brain regions, so the brain is able to work as a well-wired network system. The moment-to-moment variability in brain activity has been studied by researchers, and more specifically, in the blood oxygenation level-dependent signal.
Brain imaging explains reason for good, poor language outcomes in ASD toddlers Using functional magnetic resonance imaging (fMRI), researchers say it may be possible to predict future language development outcomes in toddlers with autistic spectrum disorder (ASD), even before they've been formally diagnosed with the condition.
Touch-sensing neurons are multitaskers Two types of touch information -- the feel of an object and the position of an animal's limb -- have long been thought to flow into the brain via different channels and be integrated in sophisticated processing regions. Now, with help from a specially devised mechanical exoskeleton that positioned monkeys' hands in different postures, researchers have challenged that view.

Clot-busting drug benefits stroke patients, brain scan study shows A drug that breaks up blood clots in the brains of stroke patients could be used more widely than at present without increased risk, a brain scan study suggests. It had previously been thought that giving the drug to people with signs of early damage in the brain caused by a stroke would increase the chances of them suffering a bleed on the brain -- which can be fatal. The study is the first to show that early tissue damage seen in brain scans does not necessarily indicate an increased risk of bleeding.

Delicate magnolia-jasmine scent activates human pheromone receptor The question if humans can communicate via pheromones in the same way as animals is under debate. Cell physiologists have demonstrated that the odorous substance Hedione activates the putative pheromone receptor VN1R1, which occurs in the human olfactory epithelium. Researchers showed that the scent of Hedione generates sex-specific activation patterns in the brain, which do not occur with traditional fragrances.
