Neural Correlates of the Unconscious and Their Role in Immune Modulation

Psychoneuroimmunology (PNI) explores the intricate relationships between the brain, immune system, and psychological processes. Emerging evidence highlights the critical role of unconscious neural mechanisms in modulating immune responses, yet this connection remains underexplored. This conceptual review synthesizes findings from neuroscience and immunology to propose an integrative model illustrating how unconscious emotion regulation—mediated by key brain regions such as the amygdala, insula, and prefrontal cortex—affects systemic immunity via neuroendocrine and autonomic pathways. Understanding these implicit processes offers promising avenues for novel interventions targeting immune-related disorders. Future research should integrate neuroimaging and immunological assessments to further validate these pathways.
