Supplementary Figure 6: Assessment of respiratory coupling when GC spiking is aligned to onset of breathing.
From: Broadly tuned and respiration-independent inhibition in the olfactory bulb of awake mice
a) Histogram (bin size = 0.1) of respiratory coupling strength (r) for anesthetized state awake state GCs. As with alignment to peak inspiration, GCs still show weak respiratory coupling. (b) Heatmap depicting baseline respiratory phase spike histograms for all awake state GCs (bin size = pi/10). Each row is a cell, and for each cell, spike count is normalized to the maximal bin for that cell. White dots denote the mean phase angle of firing for each cell. A representative breath trace is shown in black (top). Grey box in trace represents the inhalation period. (c) Histogram of mean firing phase for all cells during wakefulness (gray).
