Associative account of self-cognition: extended forward model and multi-layer structure.

Sugiura M - Front Hum Neurosci (2013)

Bottom Line: The interpersonal self, representing the attention or intentions of others directed at the self, is supported by several amodal association cortices in the dorsomedial frontal and lateral posterior cortices.Additionally, these three categories exist within a hierarchical layer structure based on developmental processes that updates the schema through the attribution of prediction error.In this account, most of the association cortices critically contribute to some aspect of the self through associative learning while the primary regions involved shift from the lateral to the medial cortices in a sequence from the physical to the interpersonal to the social self.

ABSTRACT
The neural correlates of "self" identified by neuroimaging studies differ depending on which aspects of self are addressed. Here, three categories of self are proposed based on neuroimaging findings and an evaluation of the likely underlying cognitive processes. The physical self, representing self-agency of action, body-ownership, and bodily self-recognition, is supported by the sensory and motor association cortices located primarily in the right hemisphere. The interpersonal self, representing the attention or intentions of others directed at the self, is supported by several amodal association cortices in the dorsomedial frontal and lateral posterior cortices. The social self, representing the self as a collection of context-dependent social-values, is supported by the ventral aspect of the medial prefrontal cortex and the posterior cingulate cortex. Despite differences in the underlying cognitive processes and neural substrates, all three categories of self are likely to share the computational characteristics of the forward model, which is underpinned by internal schema or learned associations between one's behavioral output and the consequential input. Additionally, these three categories exist within a hierarchical layer structure based on developmental processes that updates the schema through the attribution of prediction error. In this account, most of the association cortices critically contribute to some aspect of the self through associative learning while the primary regions involved shift from the lateral to the medial cortices in a sequence from the physical to the interpersonal to the social self.

Neural correlates of interpersonal self. Relevant cortical areas are schematically illustrated on the lateral (top panel) and medial (bottom panel) surface of the right hemisphere (A). TPJ: temporoparietal junction, pSTS: posterior part of the superior temporal sulcus, ATC: anterior temporal cortex, dMPFC: dorsal part of the medial prefrontal cortex, and ACC: anterior cingulate cortex. Examples of neuroimaging data: activation during the perception of self-directed eye-gaze or the hearing of one’s own name [(B); (Kampe et al., 2003)], and activation during real communication relative to non-real condition [(C); (Jeong et al., 2011)].

Examples of neuroimaging data: activation during the perception of self-directed eye-gaze or the hearing of one’s own name [(B); (Kampe et al., 2003)], and activation during real communication relative to non-real condition [(C); (Jeong et al., 2011)].

Mentions: The activation related to this awareness is observed in several amodal association cortices in the medial frontal and lateral posterior cortices (Figure 2A). Although varying widely across studies, activation has been identified in the MPFC encompassing the adjacent anterior cingulate cortex (ACC) (Kampe et al., 2003; Schilbach et al., 2006; Steuwe et al., 2012), the TPJ/pSTS (Pelphrey et al., 2004a; Schilbach et al., 2006; Steuwe et al., 2012), the anterior temporal cortex (ATC) (Kawashima et al., 1999; Calder et al., 2002; Kampe et al., 2003; Wicker et al., 2003), the insula (Kawashima et al., 1999; Calder et al., 2002; Schilbach et al., 2006), and the cerebellum (George et al., 2001; Wicker et al., 2003; Schilbach et al., 2006) during the perception of directed, rather than averted, eye-gaze. Activation of the MPFC/ACC, TPJ/pSTS, and ATC has also been reported in studies that compare activation during the hearing of one’s own name with the hearing of others’ names (Figure 2B) (Kampe et al., 2003; Perrin et al., 2005; Tacikowski et al., 2011). Activation is also observed in these regions when subjects believe that they are interacting with a real person rather than engaging in a similar but non-real interaction (Figure 2C) (Rilling et al., 2004; Jeong et al., 2011). Additionally, subjects who score higher on the Self-Consciousness Scale (Fenigstein et al., 1975) show a larger degree of activation in the dorsal part of the MPFC (dMPFC) during a simple sensorimotor (deviant letter detection) task (Eisenberger et al., 2005).
