Abstract

Higher cognitive functions depend upon dynamically unfolding brain network interactions. Autobiographical recollection – the autonoetic re-experiencing of context rich, emotionally laden, personally experienced episodes – is an excellent example of such a process. Autobiographical recollection unfolds over time, with different cognitive processes engaged at different times throughout. In this paper we apply a recently developed analysis technique – event related independent components analysis (eICA) – to study the spatiotemporal dynamics of neural activity supporting autobiographical recollection. Participants completed an in-scanner autobiographical recollection paradigm in which the recal..
