Neuroscience

A temporal pattern of activity observed in human brains may explain how we can learn so quickly.

For all their triumphs, AI systems can’t seem to generalize the concepts of “same” and “different.” Without that, researchers worry, the quest to create truly intelligent machines may be hopeless.

Researchers have finally seen how some smell receptors bind to odor molecules. The work yields new insights into one of the most mysterious and versatile senses.

Studies of sleep are usually neurological. But some of nature’s simplest animals suggest that sleep evolved for metabolic reasons, long before brains even existed.

Eve Marder’s research into the plasticity and resilience of nervous systems finds universal principles guiding life’s responses to stress.

Advances in brain-computer interface technology are impressive, but we’re not close to anything resembling mind control.

A newfound hub of immune system activity at the back of the brain solves a century-old puzzle.

Anesthesia is very different from sleep — which is why it offers unique opportunities for studying the human brain, says the physician-researcher and statistician Emery Brown.

Some populations of neurons simultaneously process sensations and memories. New work shows how the brain rotates those representations to prevent interference.
