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.
Two new technologies are helping scientists understand new aspects of organ and nervous system development in C. elegans. One allows them to image worms developing in a natural environment, while the other makes it possible to track single neurons as the worms grow.
Since the first case was documented in the United States in 1938, the causes of autism have remained elusive. Hundreds of genes, as well as environmental exposures, have been implicated in these brain disorders. Sex also seems to have something to do with it: About 80 percent of children diagnose...
