**Selfhood** refers to the cognitive and neural mechanisms that generate the continuous, integrated sense of being a distinct individual. It encompasses the representation of one’s body, agency, and continuity across time, and serves as a central construct in the study of [[Consciousness]] and [[Identity]]. Selfhood emerges from dynamic interactions between perceptual, mnemonic, and regulatory systems that maintain the stability of personal identity and agency. These neurocognitive mechanisms allow the organism to predict, interpret, and control its own behavior within an integrated model of the self. ## Core Dimensions - [[Minimal Self]] - The immediate, pre-reflective awareness of being an embodied subject - Characterized by [[Agency]], [[Ownership]], and moment-to-moment [[Interoception]] - [[Narrative Self]] - The temporally extended sense of identity built from [[Autobiographical Memory]] and social context - Supported by [[Language]] and higher-order reflective processes - [[Bodily Self]] - Grounded in multisensory integration of interoceptive, proprioceptive, and exteroceptive signals - Associated with activity in the [[Insula]], [[Somatosensory Cortex]], and [[Temporoparietal Junction]] ## Neural Basis - [[Default Mode Network (DMN)]] - Central to self-referential processing, autobiographical retrieval, and internal mentation - Involves the [[Medial Prefrontal Cortex (mPFC)]], [[Posterior Cingulate Cortex]], and [[Precuneus]] - [[Salience Network]] - Detects and integrates interoceptive and emotional salience of self-related stimuli - Coordinates with the DMN to regulate self-focus and context switching - [[Frontoparietal Control Network (FPCN)]] - Supports executive regulation and cognitive flexibility in self-related thought - Enables top-down modulation of internal and external attention ## Empirical Research - Behavioral and neuroimaging studies identify self-referential processing as a distinct cognitive domain involving medial cortical midline structures - Experimental paradigms investigate self-recognition, agency attribution, and self-other distinction through techniques such as mirror self-recognition, source monitoring, and [[Theory of Mind (ToM)|perspective-taking]] tasks - Disruptions in selfhood are associated with clinical conditions including [[Depersonalization Disorder]], [[Schizophrenia]], and [[Dissociative Identity Disorder]]
