Scientists complete largest wiring diagram and functional map of the brain to date

From a tiny sample of tissue no larger than a grain of sand, scientists have come within reach of a goal once thought unattainable: building a complete functional wiring diagram of a portion of the brain.

Even under stress, male-female pairs had each other’s backs

When faced with a potential threat, mice often freeze in place. Moreover, when two animals are together, they typically freeze at the same time, matching each other’s periods of immobility. In a new study, researchers found that coordination during fea…

Groundbreaking study reveals changes in brain cell composition and gene activity in Tourette syndrome

In the first comprehensive, cell-by-cell analysis of brain tissue from individuals with Tourette syndrome, researchers have pinpointed exactly which cells are perturbed and how they malfunction, revealing how different types of brain cells are affected…

Childhood experiences shape the brain’s white matter with cognitive effects seen years later

Investigators have linked difficult early life experiences with reduced quality and quantity of the white matter communication highways throughout the adolescent brain. This reduced connectivity is also associated with lower performance on cognitive ta…

First insights into how excitatory and inhibitory brain signals change as people age using wearable scanner

A study has shown how aspects of brain function change with age, revealing that excitatory processes in the brain decrease, while inhibitory processes increase as children get older. The findings are an important step in understanding conditions like a…

Brain’s own repair mechanism: New neurons may reverse damage in Huntington’s disease

New research shows that the adult brain can generate new neurons that integrate into key motor circuits, findings that may point to a new way to treat neurogenerative disorders.

Molecules that fight infection also act on the brain, inducing anxiety or sociability

Scientists find the protein IL-17 that fights infection also acts on the brain, inducing anxiety or sociability. This adds to evidence that immune molecules can influence behavior during illness.

Exposure to air pollution may harm brain health of older adults

Long-term exposure to high levels of air pollution may harm the brain health of older adults in England, finds a new study.

Could targeting Parkinson’s outside of the brain improve symptoms?

Parkinson’s doesn’t just affect movement and the brain — it may also impact the heart, according to new research. Scientists suggest that targeting a key protein outside of the brain could help manage Parkinson’s-related heart issues.

17 modifiable risk factors shared by stroke, dementia, and late-life depression

In a new extensive systematic review, researchers identified 17 modifiable risk factors that are shared by stroke, dementia, and late-life depression. Modifying any one of them can reduce your risk of all three conditions. The findings provide evidence…
