The human brain accounts for roughly 2% of total body weight but uses approximately 20% of our body's energy. Relative to our body size, human brains are much larger than those of other mammals and ...
What Bruner calls “braking,” the Yale neuroscientist Amy Arnsten calls “regulation”—specifically, calcium regulation, which ...

An ancient virus left its mark on chimpanzee DNA even after millions of years and may have helped shape human brain evolution
Millions of years ago, a virus infected the ancestors of chimpanzees and left behind a genetic souvenir. Humans never ...
Researchers led by Dr. Alexandros Karakostis from the Institute for Archaeological Science and the Senckenberg Center for Human Evolution and Palaeoenvironment at the University of Tübingen suggest ...
The human brain is three times bigger than a chimp's and more spherical than a Neanderthal's. Within a maze of bumps and grooves, neurons converse in distinct patterns that give humans unique ...
A new study reveals that changes to the gut microbiome can change the way the brain works. Humans have the largest relative brain size of any primate, but little is known about how mammals with larger ...
Researchers reveal how gut microbes shape metabolic strategies to fuel larger brains, offering a glimpse into the evolutionary biology of primates. Putative model for microbial influences on the ...
Scientists have discovered why common marmosets have unusually small, smooth brains despite starting development much like ...
The large, capable human brain is a marvel of evolution, but how it evolved from a smaller primate brain into the creative, complex organ of today is a mystery. Scientists can pinpoint 'when' our ...
Modern humans, Neanderthals, and other recent relatives on our human family tree evolved bigger brains much more rapidly than earlier species, a new study of human brain evolution has found. The study ...
Could social bonds be the key to human big brains? A study of the fossil teeth of early Homo from Georgia dating back 1.77 million years reveals a prolonged childhood despite a small brain and an ...
Fossils in Brazil indicate a more complex evolutionary history for ray-finned fish brains than previously anticipated, according to new research. The researchers not only found well-preserved brains ...
