It doesn’t matter if it’s Bach, the Beatles, Brad Paisley or Bruno Mars. Your favorite music likely triggers a similar type of activity in your brain as other people’s favorites do in theirs. Continue reading “Music has powerful (and visible) effects on the brain”
Brain can navigate based solely on smells
Northwestern University researchers have developed a new “smell virtual landscape” that enables the study of how smells engage the brain’s navigation system. The work demonstrates, for the first time, that the mammalian brain can form a map of its surroundings based solely on smells. Continue reading “Brain can navigate based solely on smells”
Decision-making is shaped by individual differences in the functional brain connectome
Each day brings with it a host of decisions to be made, and each person approaches those decisions differently. A new study by University of Illinois researchers found that these individual differences are associated with variation in specific brain networks — particularly those related to executive, social and perceptual processes. Continue reading “Decision-making is shaped by individual differences in the functional brain connectome”
Neanderthals mated with modern humans much earlier than previously thought, study finds
Using several different methods of DNA analysis, an international research team has found what they consider to be strong evidence of an interbreeding event between Neanderthals and modern humans that occurred tens of thousands of years earlier than any other such event previously documented. Continue reading “Neanderthals mated with modern humans much earlier than previously thought, study finds”
Worldwide study triples number of known genetic risk factors for stroke
A landmark international study of DNA samples from 520,000 individuals worldwide — including 67,000 affected individuals — identified 22 new genetic risk factors for stroke. Sudha Seshadri, M.D., of UT Health San Antonio, is senior co-author of this largest genetic study of stroke to date. Nature Genetics published the results online today [March 12/2018]. Continue reading “Worldwide study triples number of known genetic risk factors for stroke”
Study sheds light on how ‘dopamine neurons’ contribute to memory formation in humans
Research from Cedars-Sinai sheds light on how the human brain rapidly forms new memories, providing insights into potential new treatments for memory disorders. Continue reading “Study sheds light on how ‘dopamine neurons’ contribute to memory formation in humans”
