From autopoiesis to neurophenomenology: Francisco Varela's exploration of the biophysics of being.

Biological research January 1, 2003 David Rudrauf, Antoine Lutz, Diego Cosmelli et al. 194 citations

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."

Microcognitive science: bridging experiential and neuronal microdynamics.

Frontiers in human neuroscience January 1, 2013 Claire Petitmengin, Jean-Philippe Lachaux 90 citations

Neurophenomenology aims to combine neural and experiential descriptions of cognitive processes, but faces a practical difficulty: neural measures typically have coarser functional selectivity than the micro-dynamics of brief mental events. A new approach is proposed, using human intra-cerebral EEG (iEEG) to capture neural micro-dynamics with millimetric and millisecond precision, alongside disciplined elicitation techniques for accessing experiential micro-dynamics. This lays the foundation for a microcognitive science that practically implements neurophenomenology to investigate human cognition at the subsecond level.
