Prenatal Origins of Predictive Organization: The Custom Multiscale Oscillatory Organization Hypothesis

Prediction is widely considered a fundamental principle of brain function, yet its developmental origin remains poorly understood. Existing theories typically place the emergence of predictive architecture in postnatal cortical learning. Here we propose an earlier developmental substrate in which predictive organization begins to form prenatally through multiscale temporal coordination within the maternal–fetal system. We introduce the Custom Multiscale Oscillatory Organization Hypothesis (CMOOH), which suggests that the fetus develops within a structured oscillatory environment generated by interacting maternal physiological rhythms, including cardiac, respiratory, mechanical, acoustic, and endocrine processes. Repeated exposure to these temporally structured signals may gradually align fetal neural–autonomic dynamics through a mechanism termed Prenatal Predictive Resonance (PPR). Over time, this interaction stabilizes an individualized coordination architecture referred to as Custom Multiscale Oscillatory Organization (CMOO). Within this framework, prediction initially emerges not as representational inference but as phase-based temporal anticipation that reduces organism-level uncertainty across interacting biological systems.
