A free-energy principle has been proposed recently that accounts for action, perception and
learning. This Review looks at some key brain theories in the biological (for example, neural …

Motor learning encompasses a wide range of phenomena, ranging from relatively low-level
mechanisms for maintaining calibration of our movements, to making high-level cognitive …

Abstract Several models propose Motor Imagery, Action Observation, and Movement
Execution recruit the same brain regions. There is, however, no quantitative synthesis of the …

Motor control is the study of how organisms make accurate goal-directed movements. Here
we consider two problems that the motor system must solve in order to achieve such control …

While the cerebellum's role in motor function is well recognized, the nature of its concurrent
role in cognitive function remains considerably less clear. The current consensus paper …

Although familiar to each of us, the sensation of inhabiting a body is ineffable. Traditional
senses like vision and hearing monitor the external environment, allowing humans to have …

Motor skills can take weeks to months to acquire and can diminish over time in the absence
of continued practice. Thus, strategies that enhance skill acquisition or retention are of great …

Speech production has been studied predominantly from within two traditions,
psycholinguistics and motor control. These traditions have rarely interacted, and the …

Abstract Syntax, the structure of sentences, enables humans to express an infinite range of
meanings through finite means. The neurobiology of syntax has been intensely studied but …

We have previously tried to explain perceptual inference and learning under a free-energy
principle that pursues Helmholtz's agenda to understand the brain in terms of energy …
