More recently, however, it has become apparent that the medial prefrontal cortex (mPFC) might not have a unitary function in social cognition, but instead that there are several anatomical areas that comprise mPFC and that make dissociable contributions. Prominently, in monkeys, lesions of the gyral part of anterior cingulate cortex (ACCg; areas 24a/b) decrease interest in conspecifics (Rudebeck et al., 2006) and in humans ACCg signals track information related to other people (Reviewed elsewhere, Apps et al., 2016, 2013; Behrens et al., 2008; Lockwood, 2016; Wittmann et al., 2018). It has been proposed that ACCg signals may reflect the motivational state of others (Apps et al., 2016; Lockwood, 2016) whereas the ACC sulcus dorsal to the gyrus may play a domain-general role in coding motivation of both self and others (Apps et al., 2016; Wittmann et al., 2018). In contrast to the ACCg and the above-mentioned dorsomedial parts of prefrontal cortex (Schurz et al., 2014), recent studies shed light on the role of more ventral portions of anterior cingulate cortex in social cognition, the perigenual anterior cingulate cortex (pgACC) and
