Scientists at the Indian Institute of Technology, Madras (IIT-M) have created what they describe as the world’s most detailed 3D cellular atlas of the human brainstem, linking whole-brain MRI views to individual neurons across more than 500 tissue sections. The free online atlas, called Anchor, could help researchers better understand diseases such as Alzheimer’s, Parkinson’s, stroke, and SIDS by showing how healthy and diseased brain tissue differs cell by cell. The BBC reports: Built from high-resolution microscope images rather than costlier molecular techniques, it creates a detailed three
