neuralib.locomotion.spatial.place_field(signal, baseline, threshold, window=100, track_length=150)[source]

Detect place fields from position-binned calcium activity.

Bins where the trial-averaged activity exceeds threshold fraction of the (peak − baseline) range are labelled as place field regions. Four boundary cases (NN / NP / PN / PP) handle fields that start or end at the track edges.
