Figure 5. Correlation between TMS-induced changes in information bonus, $A$, and TMS-induced changes in the prior mean, $R_0$.

(A, B) Samples from the posterior distributions over the TMS-related changes in prior mean, $R_0$, and TMS-related change in information bonus in horizon 1 (A) and horizon 6 (B). In both cases we see a negative correlation between the change in $R_0$ and the change in $A$ consistent with a tradeoff between these variables in the model. (C) Samples from the posterior over the effect of TMS stimulation on the horizon-related change in information bonus, $\mathrm{\Delta }A=A(h=6)-A(h=1)$ plotted against samples from the TMS-related change in prior mean. Here we see no correlation between variables and the majority of ${\displaystyle \mathrm{\Delta }A(\mathrm{v}\mathrm{e}\mathrm{r}\mathrm{t}\mathrm{e}\mathrm{x})-\mathrm{\Delta }A(\mathrm{R}\mathrm{F}\mathrm{P}\mathrm{C})}$ samples below zero consistent with an effect of RFPC stimulation on directed exploration.
