TLDR
Modelling of the heart, and its experimental basis, is used to show that downward causation is necessary and that this form of causation can be represented as the influences of initial and boundary conditions on the solutions of the differential equations used to represent the lower level processes.
Abstract
Must higher level biological processes always be derivable from lower level data and mechanisms, as assumed by the idea that an organism is completely defined by its genome? Or are higher level properties necessarily also causes of lower level behaviour, involving actions and interactions both ways? This article uses modelling of the heart, and its experimental basis, to show that downward causation is necessary and that this form of causation can be represented as the influences of initial and boundary conditions on the solutions of the differential equations used to represent the lower level processes. These insights are then generalized. A priori, there is no privileged level of causation. The relations between this form of ‘biological relativity’ and forms of relativity in physics are discussed. Biological relativity can be seen as an extension of the relativity principle by avoiding the assumption that there is a privileged scale at which biological functions are determined.

Neuroscience Needs Behavior: Correcting a Reductionist Bias

TL;DR: A more pluralistic notion of neuroscience is advocated when it comes to the brain-behavior relationship: behavioral work provides understanding, whereas neural interventions test causality.

Introduction à l'étude de la médecine expérimentale

Fabrice Gzil
TL;DR: Gzil met en relief les enjeux contemporains of cette demarche as discussed by the authors : de fait, les reflexions de Claude Bernard sur les interets and les limites des modeles animaux, son analyse des problemes lies a l'experimentation sur les sujets humains, and encore son plaidoyer en faveur de l'articulation entre la clinique and la recherche medicale, font de l" Introduction une reference fondatrice pour aborder les questions que rencontre la

The roles of microclimatic diversity and of behavior in mediating the responses of ectotherms to climate change.

TL;DR: A set of models that simulate ectotherms moving on a thermal landscape according to simple sets of diffusion-based rules indicate that both simple behavioral rules and interactions between body size and spatial patterns of thermal variation can profoundly affect the distribution of realized body temperatures experienced by ectotherm.

The algorithmic origins of life.

TL;DR: It is proposed that the emergence of life may correspond to a physical transition associated with a shift in the causal structure, where information gains direct and context-dependent causal efficacy over the matter in which it is instantiated.

Knowing one's place: a free-energy approach to pattern regulation

TL;DR: This work offers a proof of principle that self-assembly is an emergent property of cells that share a common (genetic and epigenetic) model of organismal form and suggests an interpretation of genetic codes as parametrizing a generative model—predicting the signals sensed by cells in the target morphology—and epigenetic processes as the subsequent inversion of that model.

A quantitative description of membrane current and its application to conduction and excitation in nerve

TL;DR: This article concludes a series of papers concerned with the flow of electric current through the surface membrane of a giant nerve fibre by putting them into mathematical form and showing that they will account for conduction and excitation in quantitative terms.
