Brain Research::Do we have free will? ♦ Helmetless-tackling drills significantly reduce head impact ♦ Newly discovered windows of brain plasticity may help stress-related disorders

Helmetless-tackling drills significantly reduce head impact Sparked by national debate and efforts to help make football safer for players, research has found that a novel set of helmetless-tackling drills are effective in reducing head impacts by 28 percent in one season.
Newly discovered windows of brain plasticity may help stress-related disorders Even under repeated stress, the brain maintains the potential to adapt and recover. Researchers have shown how changes in gene expression cause these transitory opportunities to open up. Their results suggest well-timed treatment could change the trajectory of a brain suffering from a stress-related disorder.
Activity of Brain Proteins Associated with Memory Impairment in Alzheimer’s Identified Researchers at a laboratory for research of molecular and cellular mechanisms underlying learning and memory found that “repairing” the activity led to an improvement in memory. A start-up they established on the basis of the findings will attempt to develop drugs delaying the onset of cognitive symptoms.
The brain-computer duel: Do we have free will? Our choices seem to be freer than previously thought. Using computer-based brain experiments, researchers studied the decision-making processes involved in voluntary movements. The question was: Is it possible for people to cancel a movement once the brain has started preparing it? The conclusion the researchers reached was: Yes, up to a certain point -- the 'point of no return'.
