“…Physiologically, error detection is accompanied by skin conductance responses and changes in heart rate (Hajcak et al, 2003(Hajcak et al, , 2004, and both ACC and (especially) the insula are implicated in such responses (Kuniecki et al, 2003), as well as in cortisol and energy (glucose) regulation (Allport et al, 2004;Christensen et al, 2004;Ottowitz et al, 2004) and errorrelated processes (Menon et al, 2001). Additionally, both ACC and insula have a necessary role in the normal occurrence of the ERN (Ullsperger et al, 2002;Ullsperger and Cramon, in press) and are implicated by neuroimaging studies in depersonalization (Lanius et al, 2005;Phillips et al, 2001) and in risk-avoidance and punishment in relation to neuroticism (Paulus et al, 2003). Interestingly, administration of the anxiolytic benzodiazepine lorazepam has been related to decreased cortisol mobilization (Collomp et al, 1994;Hellhammer et al, 1988), decreased ERN amplitude (De Bruijn et al, 2004) and decreased insula activity (Paulus et al, 2005).…”
