The primary objective of this scientific exhibit is to provide an in-depth radiologic journey through the complex architecture of cerebral white matter. By leveraging advanced Diffusion Tensor Imaging (DTI) and tractography, this work seeks to:

• Elucidate the physical, mathematical, and technical foundations of DTI, from the concept of Brownian motion to the generation of the diffusion tensor.

• Detailed the methodology behind tractography reconstruction, including seed placement, tracking algorithms (deterministic vs. probabilistic), and the importance of region-of-interest (ROI) selection.

• Provide a systematic, step-by-step anatomical mapping of the brain’s "bridges," categorized into association, commissural, and projection fibers, following a strict neuroanatomical and radiologic correlation.

• Correlate historical neuroanatomical milestones with modern clinical cases, such as "Sacre Bleu" (Baudelaire) and Phineas Gage, to illustrate the impact of white matter disconnection syndromes.

• Demonstrate the clinical relevance of tractography in preoperative planning, particularly in the preservation of eloquent pathways during neurosurgical interventions.
