Abstract
Modern techniques for measuring neuronal activity using fluorescent biosensors and ultra-fast microscopy have allowed neuroscientists unprecedented access to neural information processing in vivo.The time series datasets generated from experiments sampling somatic action potentials from populations of neurons, or full-dendritic arbor sampling of populations of synapses, are becoming increasingly larger as new technologies allow for faster acquisition rates and higher temporal resolution of neural signals.Neuronal activities are sourced from an ever-expanding library of fluorescent indicators of distinct measures, including detectors of calcium, membrane voltage, and a range of neurotransmitters and neuromodulators.These biosensors are impacted by their unique molecular kinetics and inherent signal-to-noise properties.The quality of neural signal data sets are also impacted by acquisition instruments, which differ in sensitivity and sampling rate.All of these features, including underlying neural signals, biosensor properties, and microscope capabilities, must be considered during post-imaging signal processing with techniques that can scale to the size of modern neural datasets.To address this problem, here, we describe pyNeuroTrace, an open-source Python library developed to aid in processing neuronal signals from large fluorescent biosensor data sets, which allows dynamic control of filtering and signal processing with these unique aspects in mind before analyses of the underlying neuronal activity can be conducted.

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 it
