By studying rhesus monkeys, researchers have identified a brain network dedicated to processing social interactions—a discovery that offers tantalizing clues to the origins of our ability to understand what other people are thinking.
Scientists have discovered a common mutation that might explain why some people have trouble going to sleep at night and getting up early. The gene alteration slows the internal biological clock that regulates our sleeping patterns.
In some people whose cognitive functions are weakened due to Alzheimer’s, the disease can be traced back to changes in the brain’s blood vasculature. Scientists have found that a protein involved in blood clotting and inflammation might offer a potential path to new drugs.
