A specific brain region develops over time to become the seat of the self
Neuroscientific evidence supports the view that specific cortical midline structures, particularly regions of the medial prefrontal cortex, develop and function as key neural substrates underlying self-referential processing and the seat of the self.
The retrieved papers consistently demonstrate that self-referential processing and self-appraisal rely heavily on specific brain regions, most notably the medial prefrontal cortex (MPFC) and cortical midline structures (CMS). Studies like those by Northoff, Gusnard, and others point to these areas as anatomical correlates of the self, and developmental/fMRI studies show how these functional networks evolve and organize from childhood to adulthood. None of the provided papers refute the localization of self-referential processing to these structures, leading to a verdict of SUPPORTED.

Distinct Regions of the Medial Prefrontal Cortex Are Associated with Self-referential Processing and Perspective Taking. 2007. https://doi.org/10.1162/jocn.2007.19.6.935
Identifies specific subregions of the medial prefrontal cortex as being explicitly associated with self-referential processing.
