Markov Blanket

The gap between the Markov blanket and ontological boundaries arises from the former’s inability to capture the dynamic process through which biological and cognitive agents actively generate their own boundaries with the environment. Active inference in the FEP framework presupposes the existence of a Markov blanket, but it is not a process that actively generates the latter.

This hypothesis paper explores the current Covid-19 pandemic against the background of destructive climate change. Based on recent published theoretical findings on active inference and hierarchical Markov blanket systems, the outermost Planetary-Societal Markov blanket system is considered in terms of fractal patterns of information transfer between climate change processes at the planetary superordinate level, and the Covid-19 pandemic at the inner global societal level. It is hypothesised that this "Gaia" Markov blanket system has become unstable due to conflicted agendas on the part of global societies that undermine constructive self-evidencing active inference processes. In effect, a fractal crisis.

The Way

This work addresses the autonomous organization of biological systems. It does so by considering the boundaries of biological systems, from individual cells to Home sapiens , in terms of the presence of Markov blankets under the active inference scheme—a corollary of the free energy principle. A Markov blanket defines the boundaries of a system in a statistical sense. Here we consider how a collective of Markov blankets can self-assemble into a global system that itself has a Markov blanket; thereby providing an illustration of how autonomous systems can be understood as having layers of nested and self-sustaining boundaries. This allows us to show that: (i) any living system is a Markov blanketed system and (ii) the boundaries of such systems need not be co-extensive with the biophysical boundaries of a living organism. In other words, autonomous systems are hierarchically composed of Markov blankets of Markov blankets—all the way down to individual cells, all the way up to you and me, and all the way out to include elements of the local environment.

The Relationship

Abstract This commentary focuses upon the relationship between two themes in the target article: the ways in which a Markov blanket may be defined and the role of precision and salience in mediating the interactions between what is internal and external to a system. These each rest upon the different perspectives we might take while “choosing” a Markov blanket.

The Relationship

Abstract Cognitive Gadgets offers a new, convincing perspective on the origins of our distinctive cognitive faculties, coupled with a clear, innovative research program. Although we broadly endorse Heyes’ ideas, we raise some concerns about her characterisation of evolutionary psychology and the relationship between biology and culture, before discussing the potential fruits of examining cognitive gadgets through the lens of active inference.

To ensure optimal auditory development for the acquisition of spoken language, children with hearing loss require early diagnosis, effective ongoing audiological management, well fit and maintained hearing technology, and appropriate family-centered early intervention. When these elements are in place, children with hearing loss can achieve developmental and communicative outcomes that are comparable to their hearing peers. However, for these outcomes to occur, clinicians—early interventionists, speech-language pathologists, and pediatric audiologists—must participate in a dynamic process that requires careful monitoring of countless variables that could impact the child's skill acquisition. This paper addresses some of these variables or “red flags,” which often are indicators of both minor and major issues that clinicians may encounter when delivering services to young children with hearing loss and their families.

Catheter Directed Thrombolysis

Summary: COVID-19 is a recently identified illness that is associated with thromboembolic events. We report a case of pulmonary embolism in a patient with COVID-19, treated by catheter directed thrombectomy. A 57 year old patient presented to the emergency center with severe COVID-19 symptoms and developed massive pulmonary embolism. The patient was treated with catheter directed thrombolysis (CDT) and recovered completely. Coagulopathy associated with COVID-19 is present in all severe cases and is a dynamic process. We describe a case of massive/high risk pulmonary embolism, in a patient with COVID-19 receiving full anticoagulation, who was treated by percutaneous intervention. CDT can be an additional therapeutic option in patients with COVID-19 and pulmonary embolism that present with rapid clinical collapse.
