This field of study has its historical roots in numerous disciplines including machine learning, experimental psychology and Bayesian statistics.As early as the 1860s, with the work of Hermann Helmholtz in experimental psychology, the brain's ability to extract perceptual information from sensory data was modeled in terms of probabilistic estimation.
Predictive coding was initially developed as a model of the sensory system, where the brain solves the problem of modelling distal causes of sensory input through a version of Bayesian inference. It assumes that the brain maintains an active internal representations of the distal causes, which enable it to predict the sensory inputs. [5]
Bayesian search theory is used to search for lost objects. Bayesian inference in phylogeny; Bayesian tool for methylation analysis; Bayesian approaches to brain function investigate the brain as a Bayesian mechanism. Bayesian inference in ecological studies [49] [50] Bayesian inference is used to estimate parameters in stochastic chemical ...
The principle is used especially in Bayesian approaches to brain function, but also some approaches to artificial intelligence; it is formally related to variational Bayesian methods and was originally introduced by Karl Friston as an explanation for embodied perception-action loops in neuroscience.
Bayesian cognitive science, also known as computational cognitive science, is an approach to cognitive science concerned with the rational analysis [1] of cognition through the use of Bayesian inference and cognitive modeling. The term "computational" refers to the computational level of analysis as put forth by David Marr. [2]

Using Bayesian inference to combine prior and sensory information to estimate the position of a tennis ball. A person uses Bayesian inference to create an estimate that is a weighted combination of his current sensory information and his previous knowledge, or prior. This can be illustrated by decisions made in a tennis match. [1]
Bayesian model reduction is a method for computing the evidence and posterior over the parameters of Bayesian models that differ in their priors. [1] [2] A full model is fitted to data using standard approaches. Hypotheses are then tested by defining one or more 'reduced' models with alternative (and usually more restrictive) priors, which ...
