Tion, including stopsignal, gonogo, Stroop and flanker tasks (Wager et al. 2005; Nee et al. 2007; Levy and Wagner, 20). Based on these similarities, manage of imitation might involve interactions amongst common cognitive manage mechanisms in addition to a additional distinct imitationrelevant network. The ACC and aINS could possibly be involved in detecting and resolving conflict irrespective of the supply from the conflict, but interact with unique networks depending on the nature of conflict. In the context of imitation and action observation, the mPFC would be responsible for determining agency and thereby indicate for the aINS which representation reflects the intended action; the MNSwhere conflict first ariseswould be the target of topdown mechanisms of conflict resolution. This model is in line with a parsimonious and generalizable framework whereby a common conflict resolution program interacts using the system in which the conflicting representations happen. Certainly this is consistent with numerous previous research aiming to dissociate conflict processes. Egner and other folks have demonstrated modulation of your visual technique in tasks involving stimulus conflict (Egner and Hirsch, 2005; Egner et al. 2007), modulation of the amygdala in tasks with emotional conflict (Etkin et al. 2006; Egner et al. 2008), and motor modulation in tasks with response conflict (Egner et al. 2007; St mer et al. 2002). Ultimately, we need to note that our model of imitation handle differs somewhat from a recent study that also utilised DCM to examine imitation manage mechanisms, albeit inside the context of direct and averted gaze (Wang et al. 20b). That study was motivated by the observation that imitation interference effects have been lowered when a video showed an individual looking at the SCD inhibitor 1 site participant as in comparison with when somebody was looking away in the participant. This behavioral impact was proposed to reflect reduced topdown handle on automatic imitation in response for the social gaze stimulus (Wang et al. 20a). Results from their DCM suggested that the interaction amongst imitation handle and gaze was resulting from mPFCmediated modulation of visual inputs towards the frontal node of the MNS.

Author manuscript; offered in PMC 204 December 0.Cross et al.Pagebe the frontal MNS was identified in an interaction involving imitative congruency and eye gaze and was very far anterior. On the other hand, a much more intriguing explanation for potentially distinctive handle mechanisms in the two studies would be the distinction within the timing of imitative control. In the gaze experiment, gaze was directed toward or away from the participant ahead of the imitative task. Therefore, the effect of gaze on imitative manage is probably to take place in advance in the imitative stimulus, in a preparatory manner. In contrast, within the present study congruency effects have to reflect manage exerted in response to the imitative conflict instead of in preparation for conflict, since the require for control was unpredictable. Variations involving preparatory and reactive control mechanisms happen to be observed in other domains (Braver et al. 2007; Boy et al. 200; Braver, 202) and are plausible within this context at the same time. For example, in a scenario where imitation manage is usually implemented ahead of time (e.g. Cross and Iacoboni, 20), it could happen by changing motor system sensitivity to a.
