PM Modi Launches IIT Madras Brain Centre's Mission to Map 100-Plus Human Brains in 3D at Cell Resolution

Prime Minister Narendra Modi on Sunday, 11 October 2026, dedicated IIT Madras's Sudha Gopalakrishnan Brain Centre to the nation and launched its most ambitious programme yet: building three-dimensional, cell-resolution atlases of more than 100 post-mortem human brains, covering the whole span of life from the foetal stage to old age. At the same event in Chennai he released C-STROKE, which the centre describes as the world's first atlas of a human brain damaged by ischaemic stroke.

The announcements put an Indian lab at the centre of one of neuroscience's hardest data problems, and they show how far the country's supercomputing and imaging capacity has come.

What the mission sets out to do

Most brain atlases used today come from a handful of brains, often from Western donors, and are either low resolution or limited to small regions. The Brain Centre wants to produce whole-brain maps, at the resolution of individual cells, for more than 100 brains. These will include healthy brains at different ages and brains affected by disease.

If it succeeds, the collection is expected to be the largest set of 3D whole-brain maps at cellular resolution anywhere. Coverage of the launch said the maps should help researchers study how the brain's cellular architecture changes with development and ageing, and how neurological disorders alter it.

The scale of the effort is reflected in the team. According to IIT Madras, more than 200 researchers and technicians work at the centre, alongside more than 10 Indian medical institutions and over 30 researchers from more than 10 countries.

C-STROKE: a stroke brain, section by section

The first new product released under the mission is C-STROKE. It contains more than 1,000 annotated microscopic sections from a single stroke-affected human brain, and it maps markers of neuroinflammation, hypoxia (oxygen starvation) and axonal injury, the damage to nerve fibres that follows a stroke.

Stroke is a leading cause of death and disability in India, and most of what clinicians know about how damage spreads through tissue comes from scans that cannot resolve individual cells, or from animal models. A cell-level atlas of an actual human stroke brain gives researchers a reference for how injury is distributed in three dimensions, which could inform drug development and rehabilitation research. Those applications are still ahead; the atlas itself is the starting point.

How the maps are made

Producing a cell-resolution map of a human brain involves slicing it into thousands of very thin sections, staining and digitally scanning each one under a microscope, and then stitching the images back into a 3D volume. Each brain generates an enormous amount of image data.

The centre's 3D reconstructions were generated on Param Shakti, a supercomputer supported by the Ministry of Electronics and Information Technology (MeitY) under India's supercomputing programme. That detail matters: a project of this kind depends as much on computing and data engineering as on neuroscience, and it is being done on Indian infrastructure.

A centre built on philanthropy

The Sudha Gopalakrishnan Brain Centre was set up at IIT Madras in March 2022 with support from Infosys co-founder Kris Gopalakrishnan and Sudha Gopalakrishnan. Coverage of the launch also credited philanthropic support from Prem Watsa. Kris Gopalakrishnan has described the centre as the first of its kind in the world.

The centre already has a public track record. In December 2024 it released a dataset of the developing human foetal brain, with 5,132 brain sections digitally imaged at cell resolution, which it presented as among the most detailed such images of the foetal brain available.

Why it matters for India and beyond

Representation in brain science. Reference atlases shape how scans are read and how research is interpreted. A large library of brains from Indian donors, across all ages, adds data from a population that has been under-represented in neuroscience datasets.

A base for neurotechnology. Brain-computer interfaces, neuro-AI models and new diagnostics all depend on accurate maps of how the brain is organised. High-resolution human atlases are foundational data for that work, and building them domestically gives Indian researchers and start-ups direct access.

Capability at scale. Combining histology, high-throughput imaging and supercomputing on a 100-brain programme is a test of the research infrastructure India has been funding. The partnership with more than 10 medical institutions also matters, because ethically sourced donated brains are the slowest part of the pipeline.

What to watch

The launch sets a target; delivery will take years. The practical questions are how quickly the centre can process brains, how openly the atlases are shared with researchers worldwide, and whether clinical partners begin using C-STROKE and later datasets in stroke and dementia research. Most figures reported so far come from IIT Madras itself, and independent use of the data by other labs will be the real test of its value.
