Is the free-energy principle neurocentric? [PDF]

open access: yesNature Reviews Neuroscience, 2010
Recently, a free-energy formulation of brain function was reviewed in relation to several other neurobiological theories (The freeenergy principle: a unified brain theory? Nature Rev. Neurosci. 11, 127–138 (2010))1. Fiorillo raises some interesting questions about the formulation from a neurocentric perspective (A neurocentric approach to Bayesian ...

Predictive coding under the free-energy principle [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2009
This paper considers prediction and perceptual categorization as an inference problem that is solved by the brain. We assume that the brain models the world as a hierarchy or cascade of dynamical systems that encode causal structure in the sensorium. Perception is equated with the optimization or inversion of these internal models, to explain sensory ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Knowing one's place: a free-energy approach to pattern regulation. [PDF]

open access: yes, 2015
Understanding how organisms establish their form during embryogenesis and regeneration represents a major knowledge gap in biological pattern formation.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Free-Energy-Based Gene Mutation Detection Using LNA Probes

open access: yes, 2019
We have developed a label-free approach for direct detection of gene mutations using free-energy values that are derived from single-molecule force spectroscopy (SMFS)-based nucleic acid unbinding experiments.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Osteopathic Care as (En)active Inference: A Theoretical Framework for Developing an Integrative Hypothesis in Osteopathy

open access: yesFrontiers in Psychology, 2022
Osteopathy is a person-centred healthcare discipline that emphasizes the body’s structure-function interrelationship—and its self-regulatory mechanisms—to inform a whole-person approach to health and wellbeing.

Discerning protein pools by selective staining with self‐labeling tags

open access: yesFEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.
