Researchers in India developed ANCHOR, a high‑resolution 3D digital atlas of the human brainstem that bridges the gap between whole‑brain imaging and cellular pathology. Built from more than 500 tissue sections across multiple ages, it enables seamless zooming from MRI‑level structure to individual neurons and identifies over 200 cell clusters using chemical markers. Scientists highlight its potential for advancing understanding of Alzheimer’s, Parkinson’s, strokes, infant sudden death syndrome, and neurological effects of infections such as covid‑19. The freely accessible tool aims to support neurology, research, and neurosurgery by providing detailed spatial maps previously unavailable, and forms part of a broader initiative to scan over 100 human brains to study disease‑related structural changes at the cellular level.

Researchers at IIT Madras’s Sudha Gopalakrishnan Brain Centre have created the most detailed 3D atlas of the human brainstem, enabling seamless navigation from MRI-level structures to individual neurons. Built from high‑resolution images of tissue from different life stages, the Anchor atlas identifies more than 200 cellular clusters and nerve pathways, providing a crucial link between whole-brain imaging and cellular pathology. Scientists expect the open-access tool to advance understanding of disorders such as Alzheimer’s, Parkinson’s, stroke and SIDS, improve neurosurgical navigation, and support broader neurological research. The project reflects a growing shift in neuroscience toward integration of engineering, computation and biology, with future plans to map more than 100 whole human brains to study disease-related changes.
