Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Medical Imaging

Background:

  • Deep Brain Stimulation (DBS) is a key treatment for brain disorders.
  • Accurate electrode placement is vital for understanding DBS mechanisms in research.
  • Current methods often rely on post-mortem histology, limiting in vivo analysis.

Purpose of the Study:

  • To adapt and validate the Lead-DBS software pipeline for precise neuroimaging-based Deep Brain Stimulation electrode localization in rat models.
  • To establish a rater-independent method for electrode reconstruction in preclinical DBS research.
  • To enable in vivo electrode localization and integration with advanced imaging techniques.

Main Methods:

  • Adaptation of the open-source Lead-DBS software pipeline for rat neuroanatomy.
  • Validation of electrode localization accuracy through inter-rater concordance and comparison with histological methods.
  • Utilizing the OSS-DBS pipeline for subject-specific VTA simulation and pathway activation modeling.

Main Results:

  • The adapted Lead-DBS pipeline provides precise and rater-independent DBS electrode localization in rats.
  • Neuroimaging-based localization results are comparable to the conventional histological gold standard.
  • The study demonstrates in vivo localization capabilities, enabling integration with diffusion and functional MRI.

Conclusions:

  • Neuroimaging-based DBS electrode localization in rats is a precise, reliable, and rater-independent alternative to histology.
  • This open-source pipeline facilitates advanced preclinical research into DBS mechanisms and novel therapeutic targets.
  • The method enhances the understanding of DBS effects by enabling in vivo analysis and multimodal imaging integration.
