Researchers may have unlocked the blood-brain barrier

The brain is composed of billions of neurons—vulnerable cells that require a protective environment to function properly. This delicate environment is protected by 400 miles of specialized vasculature designed to limit ...

Brain organoids develop optic cups that respond to light

Human induced pluripotent stem cells (iPSCs) can be used to generate brain organoids containing an eye structure called the optic cup, according to a study published August 17 in the journal Cell Stem Cell. The organoids ...

Critical flaw found in lab models of the human blood-brain barrier

Cells used to study the human blood brain barrier in the lab aren't what they seem, throwing nearly a decade's worth of research into question, a new study from scientists at Columbia University Vagelos College of Physicians ...

Advances in understanding autism, based on "mosaic" mutations

Two studies in today's Nature Neuroscience, led by researchers at Boston Children's Hospital, Brigham and Women's Hospital (BWH), and Harvard Medical School (HMS), implicate mosaic mutations arising during embryonic development ...

Stem cells can repair Parkinson's-damaged circuits in mouse brains

The mature brain is infamously bad at repairing itself following damage like that caused by trauma or strokes, or from degenerative diseases like Parkinson's. Stem cells, which are endlessly adaptable, have offered the promise ...
