Abstract

Being able to plan and select appropriate behavior to estimate the effects of an action is likely to have, is central to acting intentionally. Consequently, the establishment of so-called action-effect bindings has been deemed fundamental for enabling goal-directed behavior. Yet, the neurophysiological foundations of this ability are still largely enigmatic. In this electrophysiological study with N=31 healthy individuals, we focused on theta band activity. We examined how information between functional neuroanatomical structures is exchanged to enable action-effect response specification processes (action planning). This was done by concatenating EEG-beamforming methods and nonlinear causal relationship estimation by artificial neural networks. We show that theta band activity in a network encompassing the insular cortex (IC), the anterior temporal lobe (ATL), and the inferior frontal cortex (IFC) supports the establishment of action-effect bindings. All regions revealed bi-directional effective connectivities indicating information transfer between these regions. The IC and ATL create a loop for information integration and the conceptual abstraction of it. Both structures convey processed information to the IFC, which possibly merges this information to infer/predict upcoming events – that is to actively perform action-effect integration. The study broadens the functional relevance of theta band activity in an IC-ATL-IFC network showing that basic ideomotor principles are implemented through theta band activity and effective connectivities between temporo-frontal structures.
