Extended Data Figure 3-1
Heterogeneity of glomerular output responses measured using two-photon and wide-field epifluorescence imaging. The glomerular mitral/tufted cell output exhibited diverse response types not seen in the olfactory sensory neuron input. A–H, Two-photon imaging: traces are from single trial measurements. The traces in A, B; C, D; and E, F are different glomeruli from the same imaging trial, but in three different preparations. H, Percentage response types across all two-photon output measurements. I–K, Wide-field epifluorescence imaging: glomerulus J exhibits a slow rise, and early suppression to the later odor pulses (similar to B, D). Glomerulus K exhibits a suppressed response to the odor (similar to F, G). The traces in I–K data are from the preparation shown in Figure 1. However, qualitatively similar observations were made in multiple preparations. Download Figure 3-1, TIF file.
