Health Wrap Episode 57 discusses mapping the human brain, potential of brain atlases and more

The 57th episode of Health Wrap by The Hindu delves into the process of mapping the human brain using advanced imaging and reconstruction techniques. Senior assistant editor Zubeda Hamid interviews Mohanasankar Sivaprakasam, Head of the Sudha Gopalakrishnan Brain Centre at IIT Madras, about this innovative technology. The discussion centers around C-STROKE, a recently released three-dimensional atlas of a stroke-affected brain.

Unlike traditional MRI scans, which offer images at a specific resolution, this new method enables researchers to observe brain structures in greater detail, allowing for the creation of comprehensive 3D maps. The episode explains the steps involved in preparing brain tissue, employing imaging techniques, and reconstructing the data to construct these detailed maps.

It also explores the various scientific and technological disciplines involved in the process and the potential benefits of detailed mapping in understanding the brain's structure and changes associated with neurological conditions. Another key aspect discussed is the Centre's ambitious plan to map over 100 human brains across different life stages, aiming to build a vast collection of brain maps that could aid in studying variations in brain structure, neurological conditions, and expand the resource base for brain research.

The episode also examines the potential clinical applications of these atlases, such as improving the understanding of stroke and other brain conditions. While acknowledging the promise of these maps, the discussion also highlights the significant work required to translate this research into practical clinical applications. The full episode is available on The Hindu health page alongside the complete playlist of The Health Wrap.
