Chennai: IIT Madras has developed and open-sourced the largest 3D high-resolution image repository of human fetal brains, consisting of 5,132 cellular-resolution brain sections. Named DHARANI, the dataset was created at the Sudha Gopalakrishnan Brain Centre using advanced brain mapping technology. Researchers utilized Nvidia processors to process and digitally render the intricate 3D images, the institute announced in a release.
About DHARANI and Its Significance
The DHARANI dataset stands out as a milestone in global neuroscience, offering unprecedented insights into the structural and cellular composition of the fetal brain. It provides a powerful platform for researchers worldwide to study neurodevelopmental milestones, developmental disorders, and abnormalities in fetal brain growth. The dataset is expected to accelerate progress in fields such as fetal medicine, cognitive neuroscience, and neurological imaging techniques.
Unlike traditional 2D imaging methods, the high-resolution 3D maps of DHARANI allow scientists to explore complex brain structures in greater detail, including the neuronal pathways and cortical layers critical for brain functions. This comprehensive repository fills a significant gap in neuroscience research, especially in understanding how external factors during pregnancy—such as nutrition, infections, or stress—impact brain development.
India’s Global Contribution
With India accounting for nearly one-fifth of global childbirths (approximately 25 million annually), this initiative aligns with the nation’s healthcare priorities, particularly in combating conditions like cerebral palsy, autism, and congenital neurological disorders. The data could also facilitate advancements in prenatal diagnostics and therapeutic interventions, making treatments more precise and cost-effective.
Remarkably, the project was completed at less than a tenth of the cost incurred in Western countries, with funding from the Office of the Principal Scientific Advisor to the Government of India, Infosys, Premji Invest, Fortis Healthcare, and Agilus Diagnostics.
Global Collaboration and Recognition
The research, spearheaded by Prof. Mohanasankar Sivaprakasam, Head of the Sudha Gopalakrishnan Brain Centre, involved collaboration with researchers from India, Australia, the US, Romania, and South Africa. It has been accepted for publication in a special issue of the Journal of Comparative Neurology, a century-old peer-reviewed journal known for groundbreaking contributions to neuroscience.
Expert Opinions
“This study will enable groundbreaking scientific discoveries, from quantifying neurodevelopmental disorders to improving fetal medicine,” Sivaprakasam stated. He noted that the dataset advances global understanding of the fetal brain by 20 times and is now the largest publicly available digital repository of its kind.
Kris Gopalakrishnan, Infosys co-founder, hailed the project as a testament to India’s potential in producing world-class scientific research. He emphasized the importance of multi-disciplinary, long-term research efforts in driving such achievements.
Driving the Future of Neuroscience
By making DHARANI open-source, IIT Madras has invited global collaboration, ensuring that this resource benefits researchers and healthcare professionals across diverse disciplines. It has the potential to transform how scientists and medical professionals approach fetal neurodevelopment and related disorders, paving the way for more effective and affordable solutions worldwide.
