Input from all sensory modalities: ventromedial prefrontal cortex (vmpfc) 10, 14, 25, medial 11, 12, 13, emotional behaviour, anterior cingulate cortex, area 24 and part of 32.

Salience network active when behavioural change is needed. Asymmetry of function: left = verbal and speech, right = nonverbal (ie. facial expression, note that bilateral damage cannot be replicated from lesions to either side. Heterogeneity of function: low correlation between injuries maybe because different cognitive processes are involved depending on the task. Premotor cortex selects the movements from its lexicon. Supplementary motor region involved in selecting/direction motor sequences. Limb movements or eye movements (job of frontal eye field)
