Rett syndrome is a severe developmental disorder triggered by mutations in the MECP2 gene, which researchers have recently discovered compromises the structural integrity of developing brain blood vessels. This #genetic mutation causes the overexpression of a specific #microRNA that breaks down the tight seals of the blood-brain barrier, resulting in vascular leakiness that disrupts neural function.

Scientists discover genetics behind leaky brain blood vessels in Rett syndrome

By showing the problem derives from genetic mutations that lead to overexpression of a microRNA, MIT researchers’ study points to potential treatment.

Molecular atlas of the adult Drosophila melanogaster (fruit fly) brain demonstrates that neurons retain a genetic record of their developmental origins, and that sex-specific behavioral circuits arise from a shared developmental template. Rather than building entirely separate circuits, sexual dimorphism in the brain is achieved through selective neuronal survival within shared cell lineages.

Enhancing gut-brain communication reversed cognitive decline, improved memory formation in aging mice

Aging causes changes in gut bacteria in mice, which hampers communication between the intestines and the brain. Restoring this connection helped old mice form memories as well as young animals.

Why I don’t think ‘Neuralink’ will ever be profitable

Elon Musk’s ‘brain chip’ efforts have been in the news again. But you can already see signs that reality is catching up with the hype behind the whole endeavour
