What happens when reality exceeds the brain’s ability to predict it?

In this interlude of The Observable Unknown, Dr. Juan Carlos Rey examines the neuroscience of awe and the moment when perception no longer resolves cleanly. This episode focuses on how awe states disrupt predictive processing, weaken the brain’s internal model of reality, and temporarily loosen the structure that maintains identity and continuity.

Drawing on the research of Dacher Keltner at the University of California, Berkeley, this episode defines awe as a state triggered by perceived vastness and the need for cognitive accommodation. When an experience cannot be contained within existing expectations, the mind is forced to reorganize. The result is not only emotional intensity, but a structural shift in how perception operates.

The discussion deepens through the work of Robin Carhart-Harris at Imperial College London in the 2010s, with particular attention to the default mode network. This network includes the medial prefrontal cortex, posterior cingulate cortex, precuneus, and angular gyrus, regions that support self-referential thinking, autobiographical memory, and narrative identity. When activity across this system decreases, the brain’s predictive grip weakens, and the sense of self becomes less fixed.

This episode introduces Dr. Rey’s concept of GERO from Chance As a Cultural Language: Toward a New Vocabulary of Play, Meaning, and Fate. GERO describes the condition in which meaning has not yet formed but must still be carried. In moments of awe, when perception exceeds the available model, interpretation does not arrive immediately. The observer remains in a state where experience is present but unresolved.

The episode examines how predictive processing shapes perception, how the default mode network maintains cognitive stability, and what occurs when these systems loosen under conditions of scale, novelty, or complexity. It also addresses the psychological pressure created when meaning is delayed, and the implications this has for how individuals process overwhelming or unfamiliar experiences.

This interlude challenges the assumption that perception is stable or direct. It presents a more precise view: reality is organized through internal models that can fail under certain conditions. Awe is not only an emotional state. It is a disruption of the system that makes the world intelligible.

The Observable Unknown continues its exploration at the intersection of neuroscience, philosophy, and human perception, examining not only what is experienced, but what happens when experience exceeds the mind’s capacity to explain it.

The Observable Unknown is a podcast exploring consciousness at the intersection of neuroscience, culture, and lived experience. It is written and hosted by Dr. Juan Carlos Rey of drjuancarlosrey.com and crowscupboard.com, an interdisciplinary scholar whose work bridges neuroscience, philosophy, and the interior dimensions of human experience. https://squareup.com/outreach/nyD7vi/subscribe
