Brain

More than 80 billion neurons, trillions of synapses and almost 6 kilometres of neural pathways: The brain is an anatomical masterpiece; it is our control centre, memory store, coordinator of thoughts and movement – and still puzzles science. In medicine, the focus is on neurodegenerative diseases such as Alzheimer's and Parkinson's, but also on cerebrovascular disorders such as strokes.

News • Worrying trend reversal

After 40 years of decline, stroke death rates are on the rise again

For almost four decades, stroke cases and fatalities have been on the decline. In recent years, however, signs point to a resurgence, according to an analysis of US stroke deaths from 1975 to 2019.

Article • Tissue-engineered glioblastoma model

3D brain tumour in a dish to personalize cancer treatment

It is the size of a common pencil eraser, but it could have a huge impact on the therapy of glioblastoma: Scientists in Virginia have developed a novel 3D tissue-engineered model of the brain tumour microenvironment, which can be used to assess how the glioma cell invades healthy tissue, proliferates, and reacts to chemotherapy drugs.
