For more than a century, the story of the brain has been told as a tale of neurons, with every thought and memory traced to their electrical chatter. That narrative is now being rewritten as evidence ...

Scientists rebuilt human brain circuits in the lab and discovered that the thalamus acts as a central organizer of cortical wiring. The findings offer new insight into how brain networks form and why ...

New experiments reveal how astrocytes tune neuronal activity to modulate our mental and emotional states. The results suggest ...

The human brain contains billions of connected neurons that collectively support different mental functions, including the ...

Scientists found our brain may organize behavior by activity patterns rather than fixed regions, reshaping how brain control ...

Researchers have long believed that neurons rely on glucose nearly entirely for fuel. The brain’s enormous energy requirements were presumed to be supplied by sugar alone, in contrast to muscle or ...

Why do we sometimes keep eating even when we're full and other times turn down food completely? Why do we crave salty things ...

Researchers from Sweden have discovered that the human brain continues to grow new cells in the memory region—called the hippocampus—even into old age. Using advanced tools to examine brain samples ...

From Santiago Ramón y Cajal’s hand came branches and whorls, spines and webs. Now-famous drawings by the neuroanatomist in the late 19th and early 20th centuries showed, for the first time, the ...

Sleep loss damages the fatty insulation protecting the nerve cells in our brain, according to a paper published in the ...
