Illustration of a human brain with highlighted auditory and somatosensory cortex regions for speech study

Study links speech learning and memory to auditory and somatosensory cortex, not motor cortex

A study by researchers at McGill University and Yale School of Medicine suggests that learning—and later retaining—new speech patterns depends more on brain areas that process sound and bodily sensation than on the motor cortex regions that control speech movements. The work was published in the Proceedings of the National Academy of Sciences.

Researchers propose lineage model for brain development

A new theory from scientists at Cold Spring Harbor Laboratory suggests that brain cells use their cellular family tree to organize into a complex organ. The model explains how a single starting cell can form a brain with roughly 170 billion precisely positioned neurons.

Gene mutation identified as cause of rare spastic ataxia

Researchers have discovered that mutations in the CD99L2 gene cause X-linked spastic ataxia, a rare movement disorder. The finding came from analysis of 2,811 patients with conditions affecting coordination and muscle control. The study was published in Nature Communications.

Scientists complete first full fruit fly brain and body connectome

10 Mwezi wa sita, 2026 Imeripotiwa na AI

An international research team has published the first complete map of neural connections spanning the brain and nerve cord of an adult fruit fly. The work reveals that many behaviors arise from distributed local circuits rather than centralized brain control. The connectome was released June 8 in the journal Nature.

Large genetic study uncovers new Alzheimer’s drug targets

A major analysis of genetic data has linked 127 gene locations to Alzheimer’s disease, including 48 previously unidentified ones. Researchers also flagged several genes as promising drug targets and highlighted changes in immune and nerve cells.

Intermittent energy restriction tied to shifts in brain activity and gut microbiome, small study suggests

31 Mwezi wa tano, 2026 Imeripotiwa na AI Imethibitishwa ukweli

A small 2023 study of adults with obesity in China found that an intermittent energy restriction program was associated with weight loss and changes in gut bacteria alongside altered activity in brain regions linked to appetite, cravings and self-control.
