(A) Spatial footprint (top) and signal (bottom) extracted from an
in vivo voltage imaging recording (mouse cortex L1
expressing Voltron) with simultaneous patch clamp.
(B) Inset of signal shown in (A) with patch-clamp ground truth recording
overlaid. Further insets are marked in green and magenta and shown to the
right.
(C) RMS differences between electrophysiological ground truth and
voltage imaging signal extracted by SGPMD-NMF (2.6 mV) and PMD-NMF (3.3 mV; mean
displayed by bar, n = 5 independent recordings). p = 0.038, paired 1-sided t
test.
