How the brain is affected by Huntington’s Disease

The genetic disease Huntington’s not only affects nerve cells in the brain but also has widespread effects on microscopic blood vessels according to research. These changes to the vasculature were also observed in the pre-symptomatic stages of the dise…

Brain’s structure hangs in ‘a delicate balance’

Researchers examined anatomy of neurons from humans, mice and fruit flies. They discovered that the cellular structure of the brain is at a critical point, poised between two phases. New insights could help design computational models of the brain’s co…

Protocol for creating ‘wired miniature brains’

Researchers have developed — and shared — a process for creating brain cortical organoids — essentially miniature artificial brains with functioning neural networks.

Testing immune cells in the placenta may indicate the health of fetal brain immune cells

Immune activation in a pregnant woman can occur in response to metabolic diseases like obesity, infections in pregnancy, exposure to pollution and environmental toxins, or even stress and can have negative effects on fetal brain immune cells (microglia…

Multicenter clinical study supports safety of deep general anesthesia

New research supports earlier findings that indicate that anesthesia is no more hazardous for the brain at higher doses than at lower doses.

New study reveals links between social anxiety, depression and suicidal thoughts in adolescents

A longitudinal study using a big dataset of 2,400 young people recruited from the UK found that social anxiety symptoms (measured at the outset) were significantly associated with more suicidal thoughts and other depressive symptoms two years later. Th…

Study identifies potential pathway to reducing breast cancer brain metastases

A study has identified a biological mechanism that could lead to more effective treatments for breast cancer that has metastasized to the brain.

How does oxygen depletion disrupt memory formation in the brain?

When we learn something new, our brain cells (neurons) communicate with each other through electrical and chemical signals. If the same group of neurons communicate together often, the connections between them get stronger. This process helps our brain…

Baby baboon brain anatomy predicts which hand they will use to communicate

By studying the brain anatomy of newborn baby baboons, a research group was able to predict what hand they would use to communicate after they had been weaned.

What’s going on in our brains when we plan?

An international team of scientists has uncovered neural mechanisms used in planning. Its results suggest that an interplay between the brain’s prefrontal cortex and hippocampus allows us to imagine future outcomes in order to guide our decisions.
