Understanding Motor Awareness Through Normal and Pathological Behavior
TLDR
It is shown that normal motor control depends on the functionality of a chain of neurobiological events that contribute to the construction of conscious knowledge of voluntary actions and to self-awareness.
Implicit Visuomotor Controls and Motor Behavior in Sports
TLDR
This review summarizes recent advances in the understanding of implicit visuomotor controls and may lead to a better understanding of the mechanism of motor control in sports.
Motor cognition: a new paradigm to study self–other interactions
Altered awareness of voluntary action after damage to the parietal cortex
TLDR
It is proposed that when a movement is planned, activity in the parietal cortex, as part of a cortico-cortical sensorimotor processing loop, generates a predictive internal model of the upcoming movement that might form the neural correlate of motor awareness.
The Sources of Human Volition
TLDR
A study by Desmurget et al. (1) on page 811 of this issue reveals how the brain may produce the authors' experience of initiating voluntary action.
Disrupting the experience of control in the human brain: pre-supplementary motor area contributes to the sense of agency
TLDR
Theta-burst stimulation is used to provide the first direct evidence of a pre-SMA contribution to ‘sense of agency’ (SoA) and shows the temporal linkage between voluntary actions and their external effects is reduced.
The natural philosophy of agency
A review of several theories and brain-imaging experiments shows that there is no consensus about how to define the sense of agency. In some cases the sense of agency is construed in terms of bodily
Reduced transfer of visuomotor adaptation is associated with aberrant sense of agency in schizophrenia
TLDR
Generalization was associated with subjective measures of SoA across both SZP and HC, emphasizing the major role action awareness plays in motor behavior, and suggesting that tendencies to misattribute agency, even in HC, manifest in abnormal motor performance.

Abnormalities in the awareness and control of action.
TLDR
The location of the neural damage associated with these disorders suggests that representations of the current and predicted state of the motor system are in parietal cortex, while representations of intended actions are found in prefrontal and premotor cortex.
An internal model for sensorimotor integration.
TLDR
A sensorimotor integration task was investigated in which participants estimated the location of one of their hands at the end of movements made in the dark and under externally imposed forces, providing direct support for the existence of an internal model.
Computational principles of movement neuroscience
TLDR
This goal is to demonstrate how specific models emerging from the computational approach provide a theoretical framework for movement neuroscience.
Perspectives and problems in motor learning
Maintaining internal representations: the role of the human superior parietal lobe
TLDR
This work reports a patient with a lesion of the superior parietal lobe who shows both sensory and motor deficits consistent with an inability to maintain such an internal representation of the body's state between updates, and suggests that the superior Parietal lobe is critical for sensorimotor integration.
Experiences of alien control in schizophrenia reflect a disorder in the central monitoring of action
TLDR
Patients with experiences of alien control of their thoughts and actions who formed a subgroup of those classified as schizophrenic, were significantly less likely to make error corrections in the absence of visual feedback.
Perceptual correlates of massive cortical reorganization.
TLDR
Patients after upper limb amputation are studied to explore the phenomenon of cortical areas corresponding to that limb becoming responsive to stimuli applied to the face following long-term deafferentation of one upper limb.
Is the cerebellum a smith predictor?
TLDR
This article suggests that the cerebellum forms two types of internal model, a forward predictive model of the motor apparatus and a time delays in the control loop, which delays a copy of the rapid prediction so that it can be compared in temporal register with actual sensory feedback from the movement.
Optic ataxia: a specific disruption in visuomotor mechanisms. I. Different aspects of the deficit in reaching for objects.
TLDR
The findings suggest that the 2 types of visuomotor mechanisms responsible for the proximal and distal components of visually-directed arm movements are controlled by the parietal cortex and that there should exist a hemisphere asymmetry in the functional organization of these mechanisms.
