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

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 ...

Despite lacking a hippocampus entirely—and having diverged from the mammalian lineage roughly 400 million years ago—larval ...

What makes the human brain different from that of other primates has long been a question. A new study suggests that the answer may be in a surprising twist of evolutionary fate: one of the brain’s ...

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

New research by UCLA Health and UC San Francisco has uncovered why certain brain cells are more resilient than others to the buildup of a toxic protein that is a hallmark of Alzheimer's disease and ...

How do electrical signals become "about" something? Through purely physical processes, neural networks transform activity ...

Researchers at UC San Francisco have identified a hazardous waste collector in the brain that disposes of the toxic clumps of ...

It's been estimated that the human brain contains roughly 100 billion neurons, together completing countless tasks through countless connections. So how do we make sense of the roles each of these ...

For the first time, clumps of human cells called organoids were fully integrated with the brains of rats—and influenced their behavior.
