Absence of human contact is associated with declines in cognitive function. But as the COVID-19 pandemic brings concerns about the potential harms of isolation to the fore, researchers are still hunting for concrete evidence of a causal role as well as possible mechanisms.

Rats and equations help researchers develop a theory of how our brains keep track of when events took place.

Signals from the lateral entorhinal cortex help create “time cells” in the hippocampus, according to some researchers.

Researchers discover a fragment of cord between 41,000 and 52,000 years old that points to Neanderthals’ complex cognitive abilities.

A population of North Island robins in a New Zealand sanctuary provides a unique system for investigating the memory skills of birds in the wild.

A small study finds that patients who had half their brains removed to treat epilepsy have stronger neural networks than controls, perhaps explaining how they can retain language and cognition skills.

A woman whose DNA suggested she’d develop early-onset dementia staved off cognitive decline for decades.

The Penn State University scientist was known for her work on fish’s perception of pain.

A growing body of evidence supports the theory that neural hyperactivity and hyperconnectivity precede the pathological changes that lead to neurodegeneration.
