State-Space Algorithms for Estimating Spike Rate Functions
Figure 8
(a) Firing rates with 95% confidence limits in delay period (black) and baseline period (blue). Raw count data is shown as dots for delay (black) and baseline (blue). BARS (splines) results for delay and baseline are red (green). (b) Probability of the two firing rates estimated using the state-space method in panel A being different as a function of trial. By trial 21, the ideal observer can be confident that the firing rate in the delay period is significantly different from the firing rate in the baseline period. Line colors indicate (blue), (green), and (red). (c) Trial-to-trial comparisons for the delay period firing rate showing Pr(trial (-axis) greater than trial (-axis)). The magnitude of the probabilities is represented with using the grayscale shown. Red pixels indicate where this probability is greater than 0.99. Blue pixels indicate where the probability surface falls below 0.01. From around trial 20 onwards and for the rest of the experiment, the firing rate is above the firing rate at earlier trials.
