Figure 5.

The mean fold change in beta frequency oscillatory power from baseline across all four training stages extracted from the analyses shown in Fig.4 for pre-trial initiation, odour sampling and decision/reward phases of trials

Note the transient asymmetry between left and right aPCX activity during early stages of training and the return to symmetry in Stage 4. This pattern is expressed both during odour sampling and during decision/reward phases of the trials. The standard error of the mean are displayed, although it is too small to be observed.
