Extended Data Fig. 4: EE signal in hippocampal regions (n = 88), frontal- (n = 109), and sensory-motor (n = 63) cortices.
From: Rate and noise in human amygdala drive increased exploration in aversive learning
(a) Mean and SE of the normalized FR across neurons in exploration and exploitation trials (red and green, respectively) as a function of the time from the choice. While there seems to be an exploration signal in hippocampal regions, it was not significant during the pre-choice epoch, and it was not correlated with behaviour (see main text). (b) Proportion of units with a significant effect for exploration and exploitation trials (as in Fig. 3e, ANOVA model, accounting for EE, choice identity and the sign of the prediction error). The proportion in the hippocampus was not significantly above chance (FDR corrected as in Fig. 3e). (c) The difference between explained variability (R2) in models with and without the EE predictor.
