Figure 1

Power spectra of single-cell data. Panels (a), (b) and (c) show time courses of the ratio of nuclear-to-cytoplasmic fluorescence recorded from single cells while panels (d), (e) and (f) show the corresponding power spectral densities, normalized to have unit area beneath the curve. Note that the frequencies in panels (d)-(f) are measured in units of the stimulus frequency and so the horizontal scale varies from panel to panel.
