Parkinson’s: towards early detection of the disease using quantitative MRI

When symptoms appear, the disease is already installed in the brain. Currently, there is no way to detect it before it is too late. But researchers think they have found: it would be a question of identifying tiny structures that form deep in the brain as the disease progresses. The Parkinson disease is a neurodegenerative …

Lymphatics Help “Seed” Early Zebrafish Brain Cells Psychology and Psychiatry News

In the embryonic stage of brain development, some neurons and synapses form correctly and connect, but others do not, resulting in parts and pieces being scrapped. This leaves dead or dying cells and requires the central nervous system to employ some type of cleaning crew. Microglial cells meet this challenge by “ingesting” waste products and …

It is often thought that the early embryo is fragile and needs support. However, in the early stages of development, it has the power to nourish the future placenta and instruct the uterus so that it can nest. Using “blastoids”, in vitro models of embryos formed with stem cells, Nicolas Rivron’s laboratory at IMBA has …
