Youngsters might have good cause to think they're brainier than their parents or grandparents, a new study finds.
It turns out that human brains are getting larger with each generation, potentially adding more brain reserve and reducing the overall risk ofPeople born in the 1970s have nearly 7% larger brain volume and almost 15% larger brain surface area than folks born in the 1930s, according to the results of the 75-year study.
“The decade someone is born appears to impact brain size and potentially long-term brain health,” said lead researcher Dr. Charles DeCarli, director of the University of California, DavisResearchers found gradual but consistent increases in several brain structures when they compared participants born in the 1930s to those born in the 1970s.and the hippocampus -- a region involved in language and memory -- were all larger in people born in the 1970s, results show.

New archive of ancient human brains challenges misconceptions of soft tissue preservationA new study has challenged previously held views that brain preservation in the archaeological record is extremely rare. The team compiled a new archive of preserved human brains, which highlighted that nervous tissues actually persist in much greater abundances than traditionally thought, assisted by conditions that prevent decay.
