Detection of single action potential in multi-unit postganglionic sympathetic nerve recordings in humans: A matched wavelet approach
Bibliographic record
Abstract
Sympathetic nerve activity associated with blood pressure regulation can be recorded directly using microneurography. Action potentials (APs) in the sympathetic nerve signal are dominated by colored gaussian noise. This paper proposes a novel method for detecting APs from muscle sympathetic nerve activity (MSNA) in multi-unit postganglionic recordings. The new method is based on designing a new mother wavelet matched to an actual AP template extracted from a real raw MSNA signal. To detect action potentials, the new matched wavelet was applied to the MSNA signal using a continuous wavelet transform following a thresholding procedure and detecting local maxima to estimate AP arrival times. The performance of the proposed method was evaluated using real MSNA recorded from six healthy participants and compared with two previous wavelet-based methods using a simulated MSNA signal.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
