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
