Mapping a new brain network for naming

Researchers identified two brain networks involved in word retrieval — the cognitive process of accessing words we need to speak. A semantic network processes meaning in middle/inferior frontal gyri, while an articulatory network in inferior frontal/p…

Hormone cycles shape the structure and function of key memory regions in the brain

Hormone levels fluctuate like the tides, ebbing and flowing according to carefully orchestrated cycles. These hormones not only influence the body, but can cross into the brain and shape the behavior of our neurons and cognitive processes. Recently, re…

Combinations of chronic illnesses could double risk of depression

People with multiple long-term physical health conditions are at a significantly greater risk of developing depression, a study shows.

CAR-T cell therapy for cancer causes ‘brain fog,’ study shows

Cancer treatment with a cell-based immunotherapy causes mild cognitive impairment, a Stanford Medicine team found. They also identified compounds that could treat it.

Evidence of mother-offspring attachment types in wild chimpanzees

A team of researchers has identified distinct mother-offspring attachment types in wild chimpanzees (Pan troglodytes verus). Drawing parallels with human psychology, the study provides compelling evidence that wild chimpanzee infants, like human childr…

Addressing hearing loss may reduce isolation among the elderly

Providing hearing aids and advice on their use may preserve social connections that often wane as we age, a new study shows. Its authors say that this approach could help ease the loneliness epidemic that older Americans face.

Different anesthetics, same result: Unconsciousness by shifting brainwave phase

A new study finds that an easily measurable brain wave shift of phase may be a universal marker of unconsciousness under general anesthesia.

ChatGPT helps pinpoint precise locations of seizures in the brain, aiding neurosurgeons

ChatGPT responses matched or outperformed epileptologists’ responses related to the regions where epileptogenic zones are commonly located. Yet epileptologists provided more accurate responses for the regions rarely affected.

The how and why of the brain’s division across hemispheres

Why does the brain split visual spatial perception between its hemispheres? A new review by neuroscientists examines the advantages and trade-offs, and how the brain ultimately makes vision feel seamless.

Lab-on-a-chip devices take public health into home

Engineers created a new point-of-care test that measures cortisol in saliva to help doctors diagnose depression and anxiety.
