Motor cognition and its role in the phylogeny and ontogeny of action understanding

by Vittorio Gallese, Magali Rochat, Corrado Sinigaglia - Trends in Cognitive Science , 2009
"... Social life rests in large part on the capacity to understand the intentions behind the behavior of others. What are the origins of this capacity? How is one to construe its development in ontogenesis? By assuming that action understanding can be explained only in terms of the ability to read the mi ..."
Abstract - Cited by 29 (3 self) - Add to MetaCart
. In particular, the functional properties of the mirror neuron system and its direct matching mechanism indicate that action understanding may be primarily based on the motor cognition that underpins one’s own capacity to act. This article aims to elaborate and motivate the pivotal role of such motor cognition

Early Postnatal Death and Motor Disorders in Mice Congenitally Deficient in Calnexin Expression

by Sue Brown, Gordon Stamp, Michael J. Owen , 2002
"... Calnexin is a ubiquitously expressed type I membrane protein which is exclusively localized in the endo-plasmic reticulum (ER). In mammalian cells, calnexin functions as a chaperone molecule and plays a key role in glycoprotein folding and quality control within the ER by interacting with folding in ..."
Abstract - Add to MetaCart
mice were carried to full term, although 50 % died within 48 h and the majority of the remaining mice had to be sacrificed within 4 weeks, with only a very few mice surviving to 3 months. Calnexin gene-deficient mice were smaller than their littermates and showed very obvious motor disorders

Development of Motor System Dysfunction Following Whiplash Injury

by Michele Sterling Gwendolen, Michele Sterling A, Gwendolen Jull A, Bill Vicenzino A, Justin Kenardy B, Ross Darnell C , 2002
"... Dysfunction in the motor system is a feature of persistent whiplash associated disorders. Little is known about motor dysfunction in the early stages following injury and of its progress in those persons who recover and those who develop persistent symptoms. This study measured prospectively, motor ..."

"... set about tracing the more subtle symptoms of aphasia... to factors of localization. In this way they arrived at the hypothesis of conduction aphasia, with subcortical and transcortical, and motor and sensory forms. This critical study is directed against this view of speech disorders and it seeks t ..."

Recovery of motor function in stroke survivors and parameters of its assessment

by Elza Tataradze, Naira Chabashvili
"... Motor disorders conditioned by acute disturbance of brain circulation represent the most frequent cause of severe disability. It has been suggested, that since active repetitive exercise facilitates restoration of motor function, repetitive movements induced by neuromuscular electrical stimulation ( ..."

AJ: Amyotrophic lateral sclerosis and its association with dementia, parkinsonism and other neurological disorders: a review. Brain

by Arthur J. Hudson , 1981
"... AMYOTROPHIC lateral sclerosis (ALS) is widely regarded as a disease that is confined to the voluntary motor system with progressive degeneration of the corticospinal tracts and alpha motor neurons leading to extreme muscular weakness and wasting (Munsat and Bradley, 1979). Amyotrophic lateral sclero ..."

Design of a Modular and Low-Latency Virtual-Environment Platform for Applications in Motor Adaptation Research, Neurological Disorders, and

by Daniel J. Myall, Michael R. Macaskill, Paul R. Davidson, Tim J. Anderson, Richard D. Jones, Senior Member , 2007
"... Abstract—We have developed a modular virtual environment platform for movement research and rehabilitation. The system uses several networked computers running Linux to share compu-tation. An electromagnetic tracker is the primary position tracker and both a head-mounted display and stereo goggles a ..."

Preliminary applications have confirmed that the system is a powerful tool for sensory-motor investigation and has considerable potential as a tool for neu-rorehabilitation. Its primary

Motor representation of actions in children with autism

by Sonia Boria, Cristiana Copioli, Roberta Bracceschi, Virginia Giuberti, Erica Santelli, Vittorio Gallese - PLoS ONE 7, e44779. doi: 10.1371/journal.pone.0044779 , 2012
"... Background: Children with Autistic Spectrum Disorders (ASD) are frequently hampered by motor impairment, with difficulties ranging from imitation of actions to recognition of motor intentions. Such a widespread inefficiency of the motor system is likely to interfere on the ontogeny of both motor pla ..."

Behavioral/Systems/Cognitive Temporal Discounting of Reward and the Cost of Time in Motor Control

by Reza Shadmehr, Jean Jacques, Orban Xivry, Minnan Xu-wilson, Ting-yu Shih , 2010
"... Why do movements take a characteristic amount of time, and why do diseases that affect the reward system alter control of movements? Suppose that the purpose of any movement is to position our body in a more rewarding state. People and other animals discount future reward as a hyperbolic function of ..."
Abstract - Add to MetaCart
. Therefore, each voluntary movement carries a cost because its duration delays acquisition of reward. The cost depends on the value that the brain assigns to stimuli, and the rate at which it discounts this value in time. The motor commands that move our eyes reflect this cost of time.
