Description: Distinguishing ongoing and past self-generated actions or thoughts from information actually perceived from the environment is important in our daily life. This process is classically studied by two experimental paradigms: self-monitoring and reality-monitoring which respectively evaluate online and memory-based self-agency of action or speech. In order to disentangle brain correlates underlying this process, we conducted a coordinate-based meta-analysis of 16 neuroimaging studies (369 healthy subjects) using seed-based d Mapping with permutation of subject images (SDM-PSI). Findings revealed robust meta-analytic hubs engaged in self-agency, including the left lobule VI of the cerebellum, right temporoparietal junction and left anterior cingulate cortex. The involvement of these regions is consistent with the previous models of both online and delayed self-agency. Yet, the current findings offer new insights into the common brain network underlying these two mechanisms by suggesting a neural signature of the self that may occur during self-productions and persist in memories.
