The Indian Institute of Technology-Madras (IIT-Madras) has released a elaborate three-dimensional atlas of the quality brainstem astatine compartment resolution, offering researchers an unprecedented presumption of 1 of the astir analyzable regions of the brain.
Developed by the Sudha Gopalakrishnan Brain Centre (SGBC), the atlas, named ANCHOR (Atlas of Neurochemical Characterization of the Human Brainstem with 3D Reconstruction), combines MRI, histology, and neurochemical mapping to make broad brainstem maps spanning prenatal, childhood, and big stages.
The atlas contains much than 200 brainstem nuclei and fibre tracts reconstructed from hundreds of serial sections. Eight complementary immunostains were overlaid crossed much than 500 sections to place chiseled neurochemical compartment types.
The researchers person made ANCHOR publically accessible done a dedicated portal to facilitate its usage by scientists and clinicians worldwide.
The atlas was unveiled during the 3rd BRICS Neuroscience Symposium 2026 held astatine IIT-Madras. Principal Scientific Adviser to the Government of India Ajay Kumar Sood said the maps could assistance place compartment populations affected successful brainstem lesions and assistance objective applications.
According to the institute, the atlas integrates macro-scale volumetric information with cellular-level images, enabling seamless navigation from gross encephalon structures to microscopic features.
SGBC plans to physique cell-resolution maps covering the quality lifespan and neurological diseases.
