ANCHOR: World's Most Detailed 3D Atlas of the Human Brainstem

Context

Recently, researchers at IIT Madras developed ANCHOR, a high-resolution 3D digital map of the human brainstem, providing an unprecedented view of its structure and supporting advanced neuroscience research.

About ANCHOR

  1. ANCHOR (Atlas of Neurochemical Characterization of the Human Brainstem with 3D Reconstruction) is the world’s most detailed 3D atlas of the human brainstem.
  2. Developed by the Sudha Gopalakrishnan Brain Centre (SGBC), IIT Madras, it maps the brainstem across life stages, from the prenatal period to adulthood.
  3. It employs a multimodal approach, integrating MRI, histology, and neurochemical architecture.
  4. The atlas incorporates over 200 brainstem nuclei and fibre tracts, reconstructed from hundreds of serial sections.
  5. Its high-resolution reconstruction is based on eight complementary immunostains applied across more than 500 tissue sections.
  6. It enables examination of brain structures at the micron level, providing nearly 1,000-fold higher resolution than conventional MRI.
  7. It provides a high-resolution reference framework for understanding brain development, neural connectivity, and cellular architecture.
  8. The atlas is expected to advance research on neurological and neurodegenerative disorders, supporting improved diagnosis and clinical investigations.
