Persistent homology offers a powerful tool for extracting hidden topological signals from brain networks. It captures the evolution of topological structures across multiple scales, known as filtrations, thereby revealing topological features that persist over these scales. These features are summarized in persistence diagrams, and their dissimilarity is quantified using the Wasserstein distance.

- Deep brain stimulation (DBS) is effective for treating neurological diseases, but its mechanisms are not fully understood; research on nonhuman primates (NHPs) can help uncover these mechanisms and improve therapy.
- The study involved implanting DBS electrodes in seven NHPs using a microTargeting platform, with imaging studies pre-surgery to evaluate electrode placement accuracy.
- Results showed a small electrode placement error, indicating that the microTargeting system is more effective than traditional methods, allowing for more accessible and precise DBS procedures in primates.
