“…Neuroimaging studies suggest that a frontal parietal network involved in task-rule implementation might be instrumental for the occurrence of IB-TRCEs (e.g. Hartstra, Kühn, Verguts, & Brass, 2011;Hartstra, Waszak, & Brass, 2012;Ruge & Wolfensteller, 2010). In this network, the inferior frontal sulcus appears to be implicated in the formation of S-R links, while a sizeable part of the network is responsible for the coding of responses in areas related to motor control such as the anterior IPS, premotor cortices and the pre-SMA (Hartstra et al 2012).…”

Our data suggest that this instruction-related activation in the fronto-parietal network can be sustained over time and even lead to automatic activation in the primary motor cortex during the performance of other tasks.…”

Previous behavioral studies have shown that instructions about stimulus-response (S-R) mappings can influence task performance even when these instructions are irrelevant for the current task. In the present study, we tested whether automatic effects of S-R instructions occur because the instructed stimuli automatically activate their corresponding responses. We registered the lateralized readiness potentials (LRPs) that were evoked by the instructed stimuli while participants were performing a task for which those mappings were irrelevant. Instructed S-R mappings clearly affected task performance in electrophysiological and behavioral measures. The LRP was found to deflect in the direction of the response tendency that corresponded with the instructed S-R mapping. Early activation of the instructed response was observed but occurred predominantly on slow trials. In contrast, response conflict evoked by instructed S-R mappings did not modulate the N2 amplitude. The results strongly suggest that, like experienced S-R mappings, instructed S-R mappings can lead to automatic response activation, but possibly via a different route

“…Nonetheless, emotion also modulated activity in the right SMA at 700 ms and therefore, this region is also a candidate for the representation of elapsed time. Our speculative hypothesis -based on separate evidence for the (pre-)SMA in response processing (e.g., Forstmann et al, 2008;Hartstra, Waszak, & Brass, 2012) -is that the right IFG/AI represents awareness of elapsed time whereas the SMA is responsible for preparing a response based on this information.…”

“…fMRI studies have also revealed left IFJ to be involved in the implementation of new verbal instructions in a cognitive control task (Hartstra et al, 2011). Therefore, IFJ is indeed important not only in the implementation of new stimulus response tasks, but it also has a more general function to guide brain areas needed to perform the upcoming task according to verbal instructions (Hartstra et al, 2012). The decrease in IFJ activation in EPM1 patients observed in this study could thus be associated with the difficulties in initiation or termination of motor execution, which is a typical clinical symptom in EPM1.…”
