Karl Friston, theoretical neuroscientist and authority on brain imaging, invented statistical parametric mapping (SPM), voxel-based morphometry (VBM) and dynamic causal modelling (DCM). Mathematical contributions include variational Laplacian procedures and generalized filtering for hierarchical Bayesian model inversion. Friston currently works on models of functional integration in the human brain and the principles that underlie neuronal interactions. His main contribution to theoretical neurobiology is a free-energy principle for action and perception (active inference).

The “free energy principle” provides an account of sentience in terms of active inference. Physics studies the properties that self-organising systems require to distinguish themselves from their lived world. Neurobiology studies functional brain architectures. Biological self-organization is an inevitable emergent property of any dynamical system. If a system can be differentiated from its external milieu, its internal and external states must be conditionally independent, inducing a “Markov...
