Supplementary Figure 1: Rate model captures variance in spike counts.
From: Encoding and decoding in parietal cortex during sensorimotor decision-making
(a) Peri-stimulus time variance (PSTV) histogram (thin line), and PSTH (think line) plotted simultaneously. These are targets-ON trials conditioned on coherence and decision. Both traces are computed with 50 ms boxcar moving average and smoothed with a Gaussian of 50 ms standard deviation. Note that the estimated mean and variance are close to each other, consistent with Poisson variability. (b) Population summary of PSTV power explained analogous to Fig. 3b. On average, 84.1% of the power is captured by the rate model.
