Francisco Varela's work on subjectivity and consciousness is reviewed, presenting a view of subjectivity as deeply intertwined with biological and physical roots. His theory of concrete, embodied dynamics, grounded in autonomous systems, posits that biological autonomy defines life and identity as emergent, circular self-producing processes. Embodiment explains how a cognitive self arises from an organism's internal regulation and sensorimotor coupling, with global subjective properties emerging from component interactions and constraining local processes through recursive morphodynamics. Neurophenomenology uses first-person methods to examine experience, creating mutual constraints between biophysical data and subjective accounts, aiming to ground disciplined insight in biophysical emergence. Varela's contribution is framed as a "biophysics of being."
Neurophenomenology aims to combine neuroscience with the study of conscious experience, but integrating first-person reports with brain data remains challenging. Neurofeedback, where people learn to regulate their own brain activity in real time, offers a practical way to braid together subjective experience and neural measurements. In this iterative closed-loop setup, conscious activities can directly influence neuronal patterns, illustrating downward causation. The paper discusses mechanisms that might mediate such effects and outlines future research directions.
A dynamic approach to epileptic seizure anticipation, combining neuro-dynamic analysis of brain activity with pheno-dynamic analysis of subjective experience, can guide and determine each other. This method consolidates the foundations for a cognitive, non-pharmacological therapy for epilepsy. The neuro-phenomenological co-determination demonstrated through this example offers new insight into the gap between subjective experience and neurophysiological activity.
