Fig. 1: Ultraslow oscillations in MEC neurons.
From: Minute-scale oscillatory sequences in medial entorhinal cortex
a, Neural activity was recorded through a prism from GCaMP6m-expressing neurons of the MEC in head-fixed mice running in darkness on a non-motorized wheel. Cartoon of a running mouse on the right created with BioRender.com. b, Stacked z-scored autocorrelations of single-cell calcium activity for one example session (484 neurons), plotted as a function of time lag. Neurons are sorted according to the maximum power of the PSD calculated on each autocorrelation separately, in descending order. c, PSD (left) calculated on the autocorrelation (right) of one example cell’s calcium activity. The dashed red line indicates the frequency at which the PSD peaks (0.0066 Hz). d, As in c but for another example cell. The PSD peaks at 0.0066 Hz and has harmonics at 0.0132, 0.0207 and 0.0273 Hz. e,f, As in c,d but for two example cells recorded using Neuropixels probes. The PSDs peak at 0.016 Hz (e) and 0.015 Hz (f).
