A generic, rapid and robust platform for personalized functional circuit-guided neuromodulation targeting.

Abstract

Neuromodulation approaches can target specific brain functional circuits to treat various brain disorders, and resting-state functional magnetic resonance imaging is increasingly being used to map functional circuits in individual patients for target localization. However, this strategy faces three major hurdles for clinical translation: time-intensive resting-state functional magnetic resonance imaging processing, insufficient robustness for clinical use and a lack of automated targeting solutions. Here we cover the use of a generic, rapid, robust and automated platform for personalized functional circuit-guided target planning across different neuromodulation techniques, termed Unified Platform for Neuromodulation with Individualized Target Estimation (UNITE). UNITE is computationally efficiency and robust and uses DeepPrep, a recently developed end-to-end preprocessing pipeline that achieves a tenfold speedup and improved robustness compared with state-of-the-art clinical pipeline. Using DeepPrep's preprocessed data, UNITE maps functional circuits and localizes personalized targets through automated targeting algorithms. Currently, UNITE offers three built-in transcranial magnetic stimulation-targeting algorithms for post-stroke functional rehabilitation and one focused ultrasound stimulation-targeting algorithm for Parkinson's disease. Notably, it is designed to be adapted for other brain disorders and neuromodulation applications. To ensure quality and usability, UNITE generates a data quality control report and a visual verification report of the identified targets, with target coordinates exported in multiple formats for compatibility with different neuronavigation systems. Overall, this platform enables personalized neuromodulation target localization within 30 min on a local graphics processing unit-equipped workstation. A basic level of computer science proficiency, along with neuroimaging experience, is sufficient for its use.
