Benchmarking spike source localization algorithms in high density probes

SSL algorithm robustness on simulated data (MEArec).
A: Template localization performance metrics at varying levels of electrode degradation. Performance is assessed as (i) percentage of estimated locations within 30µm of true locations (accuracy), (ii) median Euclidean distance between estimated and true locations (localization error), and (iii) estimated drift from original location. Estimated drift is the Euclidean distance between the estimated template location without degradation v. the estimated template location with degradation; i.e., a measure of how unstable the localization algorithm is against degradation. B: Spike localization performance metrics at varying levels of electrode degradation. Performance is assessed via accuracy and localization error. C: Visualization of template and spike localization estimates at varying levels of electrode degradation. Left panel is zoomed-in view of visualization outlined in red.
