Lower thresholds in <i>A-as-dev</i> are a consequence of lower <i>A-as-dev</i> non-target response magnitude.

A: in the sample network, with each neuron shown in its spatial location. Left and middle column, raw averages in the A-as-dev sequence () and A-in-con sequence (), respectively; right column, contrast between these two (). A and B stimulus locations are highlighted in the left plot; see Fig 1 for the locations of the remaining stimuli used in the A-in-con sequence. B: Average response (in spikes per trial) to non-target trials (, with N meaning B in A-as-dev, and B, C, D, and E in A-in-con). Columns are arranged as in panel A. C: Relationship across excitatory neurons of the sample network between and , and associated linear regression. D: Pearson correlation coefficients ρ of the relationship shown in the previous panel ( vs across excitatory neurons), plotted against the corresponding across data sets. Each marker corresponds to one network and target stimulus. Red markers indicate a significant positive correlation (one-sided Wald test, significance level 0.05). Inset histograms show the distribution of the corresponding values, with orange portions indicating the 95% confidence interval of the median, calculated by bootstrap with 10000 iterations.
