Extended Data Fig. 10: Orientation and phase sensitive responses.
From: Fast optical recording of neuronal activity by three-dimensional custom-access serial holography

(a) Orientation sensitivity index (OSI) for four example neurons with orientation preferences (Θpref) 178°, 78°, 171° and 12° (top to bottom). Experimental (black) with biphasic fit (red). Error bars indicate SEM. (b) Stacked peristimulus time histograms (PSTH) obtained for the neurons in (a) from 80 (# 1, #2, #4) or 50 (# 3) trials with 80 ms binning width resulting in R1/R0 ratios ranging from 1.2 to 0.04 (top to bottom). (c) Harmonic spike Rate R1 as function of the mean rate R0 in response to the preferred stimulus orientation and preferred direction for 155 neurons in layer 2/3. Responses classified according to R1/R0 larger (red) or lower (blue) than the R1/R0 ensemble mean. Linear fits to the data given as dashed lines. (d) Same as (a) for the counterpropagating direction of the preferred stimulus.
