Effects of different averaging window sizes. (A) 1 × 1; (B) 3 × 3; (C) 7 × 7. The histograms of the signals resulting from these three averaging windows are shown in (D). Bar: 500 μm. (E) Non-averaged OCT raw signal (normalized to baseline) trace showing functional responses (blue curve) corresponding to the stimulation trial (beginning of each trial is indicated by the red curve). (F) The Fourier transform of the signal trace revealing the stimulation frequency (0.05 Hz, indicated by the red arrow) and its harmonics. The inset shows an enlarged view (For interpretation of the references to color in this figure legend, the reader is referred to the web version of the article).
