Creation of a diffusion tractographic atlas of the anterior limb of the internal capsule for psychiatric DBS planning

Video Transcription

Video Summary

In this video, Garrett Banks, a neurosurgery resident at Columbia, discusses his work on creating a diffusion tractographic atlas of the anterior limb of the internal capsule (ALIC) for psychiatric neurosurgery interventions. The ALIC is important for functions related to the frontal lobe, such as cognitive control and emotional processing. It has been used as a surgical target for treating psychiatric disorders like OCD and depression. The study aimed to create a population-normalized ALIC fiber bundle atlas using data from the Human Connectome Project. The atlas was then used to analyze intraoperative stimulation data from patients receiving deep brain stimulation for OCD. The results revealed that certain fiber bundles, particularly those connected to the orbital frontal cortex, were more strongly stimulated and associated with positive mood changes. The study suggests that the atlas can aid in targeted stimulation for psychiatric neurosurgery interventions.
