In order to resolve an emotional conflict the rostal[[ACC]] inhibits the [[amygdala]] (or [[FFFF]] mechanism)<ref>[http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.126.1555&rep=rep1&type=pdf Amit Etkin, Tobias Egner, Daniel M.

This is strengthing by the findings that in panic disorder, the volume of the the ACC is reduced, <ref>[https://www.slicer.org/slicerWeb/images/2/2c/Asami-PsychiatryClinNeurosci2008.pdf Takeshi et al., Anterior cingulate cortex volume reduction in patients with panic disorder, Psychiatry and Clinical Neurosciences 2008; 62: 322–330]</ref> .

==Liberals and ACC==[[Conservatives and Liberals|Liberals]] have higher [[ACC]] gray volume<ref>Kanai R, Feilden T, Firth C, Rees G (2011) Political orientations are correlated with brain structure in young adults. Curr Biol 21: 677–680.</ref>. ACC is connected to conflict resultion (rACC to social conflict and dACC to non-social conflict). Reward valence modulates conflict-driven attentional adaptation in the ACC<ref>[http://bernhard-hommel.eu/Van%20Steenbergen%20et%20al.%20(2012).%20Reward%20valence%20modulates%20conflict-driven%20attentional%20adaptation.pdf van Steenbergen, Guido P.H.

ACC appear to encode negatively-valenced components, such as cost or effort<ref>Walton ME, Bannerman DM, Alterescu K, Rushworth MFS.

Greater liberalism was associated with stronger conflict-related [[ACC|anterior cingulate activity]], suggesting greater neurocognitive sensitivity to cues for altering a habitual response pattern<ref>[http://www.psych.nyu.edu/amodiolab/Publications_files/Amodio_etal_2007_NatureNeuro.pdf Amodio, D.

As well as more avodience of doing, due to the highten percived costs that the higher volume of the ACC can cause<ref>Suggestion: ~~~~Tal Yaron, 29/6/2014</ref>.
The ACC is important for responce time, therefore it was suggested that the ACC is related to "global energizing factor"<ref>Stuss, Donald T., Michael P. Alexander, Tim Shallice, Terence W.
