Figure 7: Cholinergic synaptic neuromodulation impacts bump tuning and diffusion, while cholinergic input decorrelation decreases bump diffusion.

A-D Top, Population tuning curves (averaged over 8 cues after recentering, with 20 trials per cue) at the end of the delay period. Bottom, Endpoint deviation (mean corrected endpoint). Blue: NB OFF condition ($J_{E0}=1.95mSc{m}^{-2}$). Orange: NB ON condition ($J_{E0}=2.24mSc{m}^{-2}$). The NB ON condition has additional modulations in B-D: in B $J_{EE}$ and $J_{IE}$ are doubled; in C $J_{EI}$ and $J_{II}$ are decreased by 20%; in D FF correlation modulation, $C_{E0}$, is divided by half. Inset, response Std in the two conditions. Error bars are 95% bootstrapped confidence intervals.
