Using quantitative EEG, BM-Science researchers examined the reproducibility of functional integrity within three operational modules of the brain’s self‑referential network - each corresponding to one of the core phenomenological aspects of the Selfhood triumvirate: ‘Self’, ‘Me’, and ‘I’.

The study is reported in the article “Trait-like stability of selfhood triumvirate and its constituent aspects: A qEEG intra-individual test–retest reliability study,” now available in Consciousness and Cognition journal.

A few highlights from the findings:

• Each individual aspect of selfhood showed moderate-to-high meaningful intraindividual stability.
• The overall configuration (the relative expression of ‘Self’, ‘Me’, and ‘I’) was exceptionally stable, suggesting a robust trait-like pattern.
• Importantly, age, time between assessments, and the presence of somatic or psychopathological conditions did not significantly influence these stability measures.

Together, the results point to the Selfhood triumvirate as a trait-like neurocognitive architecture, with varying degrees of stability across its components.
