Developmentally transient amygdala function could account for the findings observed inside the present study: The amygdala may perhaps properly be required early in improvement to acquire regular ToM skills but develop into inessential when this function has been offloaded to the mature cortical network for falsebelief reasoning. The view that amygdala function might be most important for ToM early in development is supported by evidence suggesting that it plays a critical part in the early expression of joint focus (50, five), which can be thought to be a developmental precursor to ToM (52). Sadly, we do not know the age of onset of amygdala lesions in our sufferers, while we’ve got surmised that their illnesses calcified the amygdala around age 0 y (53). Other patients with amygdala lesions, a few of them children and adolescents, are accessible, so in future research it may be possible to probe ToM abilities across development in such a group (46). Ultimately, it needs to be emphasized that the FalseBelief Localizer engages ToM beneath the demands of a distinct experimental job and depends strongly on language. When explicit cues are absent, as is definitely the case in most natural social environments, evidence suggests that patients with amygdala lesions fail to exhibit the spontaneous use of ToM (four). Furthermore, you’ll find a number of ToM tasks that don’t rely on language. As a result it could be vital to test each efficiency and brain activation patterns in sufferers who have amygdala lesions on such a larger battery of ToM tasks. It remains probable that, even in adulthood, the amygdala plays a crucial part in the bottomup control of cortical networks for ToM use, but this part can be revealed only on tasks which can be reasonably implicit in their cognitive demands, which include nonverbal tasks. This suggestion highlights the more basic theme that ToM is really heterogeneous in its behavioral expression, operational definition, and neural correlates (28, 35, 36). A far more complete investigation, for example the a single in the present paper but over a larger battery of ToM tasks, could help parse that heterogeneity into kinds that do not rely on the amygdala and sorts that may well. Conclusion We’ve shown that the amygdala will not be a essential component or modulator of your cortical network for falsebelief reasoning assessed using the FalseBelief Localizer. Conditional around the caveats we enumerated above, this conclusion was pretty robust in our data: It held clearly for wholebrain and ROIbased analyses, and it was replicated across two diverse sufferers and across two experimental sessions in every single patient. We also documented that the amygdala is indeed Dehydroxymethylepoxyquinomicin web activated in healthful participants in the FalseBelief Localizer, but that statistical power for detecting its activation needs unusually significant sample sizes.
