Brain Imaging

770
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Neuromodulation

Background:

  • Directional deep brain stimulation (DBS) offers improved control over stimulation fields.
  • Programming directional DBS systems is a complex and time-consuming process.

Purpose of the Study:

  • To validate local field potentials (LFPs) from directional DBS contacts as predictors of stimulation efficiency.
  • To assess the utility of LFPs in identifying optimal stimulation contacts for Parkinson's disease (PD) patients.

Main Methods:

  • Intraoperative LFPs were recorded from directional contacts in the subthalamic nucleus (STN) of 12 PD patients.
  • Beta activity from LFPs was compared with clinical outcomes assessed months later.

Main Results:

  • Normalized beta activity showed a positive correlation with clinical efficacy of stimulation contacts.
  • The top two contacts by beta activity identified the most efficient stimulation contact in 92% of cases.
  • These contacts also identified the widest therapeutic window in 74% of cases.

Conclusions:

  • LFPs recorded from directional DBS contacts can predict the most effective stimulation contacts.
  • This LFP-based approach may expedite the selection of optimal contacts for directional DBS, improving patient outcomes.
