Broca's area has been considered, for over a century, as the brain centre responsible speech production. Modern neuroimaging and neuropsychological evidence have suggested wider functional role is played by this area. In addition to that it involved in syntactical analysis, mathematical calculation music processing, recently shown may play some language comprehension and, more generally, understanding actions of other individuals. As magnetic resonance imaging, one cortical areas activated...
An important issue in motor control is understanding the basic principles underlying accomplishment of natural movements. According to optimal theory, problem can be stated these terms: what cost function do we optimize coordinate many more degrees freedom than necessary fulfill a specific goal? This question has not received final answer yet, since optimized partly depends on requirements task. Many functions were proposed past, and most them found agreement with experimental data....
An important question in the literature focusing on motor control is to determine which laws drive biological limb movements. This has prompted numerous investigations analyzing arm movements both humans and monkeys. Many theories assume that among all possible one actually performed satisfies an optimality criterion. In framework of optimal theory, a first approach choose cost function test whether proposed model fits with experimental data. A second (generally considered as more difficult)...
In the human brain, homologous regions of primary motor cortices (M1s) are connected through transcallosal fibers. Interhemispheric communication between two M1s plays a major role in control unimanual hand movements, and strength this connection seems to be dependent on arm activity. For instance, lesion M1 can induce an increase excitability intact abnormal high inhibitory influence onto damaged M1. This attributable either disuse affected limb or overuse unaffected one. Here, directly...
Motor resonance mechanisms are known to affect humans' ability interact with others, yielding the kind of "mutual understanding" that is basis social interaction. However, it remains unclear how partner's action features combine or compete promote prevent motor during To clarify this point, present study tested whether and nature visual stimulus properties observed actions influence observer's response, being contagion one behavioral manifestations resonance. Participants a humanoid robot...
Normal aging significantly influences motor and cognitive performance. Little is known about age-related changes in action simulation. Here, we investigated the influence of on implicit imagery.Twenty young (mean age: 23.9+/-2.8 years) nineteen elderly 78.3+/-4.5 subjects, all right-handed, were required to determine laterality hands presented various positions. To do so, they mentally rotated their match them with hand-stimuli. We showed that: (1) subjects affected ability implicitly...
Modularity in the central nervous system (CNS), i.e., brain capability to generate a wide repertoire of movements by combining small number building blocks ("modules"), is thought underlie control movement. Numerous studies reported evidence for such modular organization identifying invariant muscle activation patterns across various tasks. However, previous relied on decompositions differing both nature and dimensionality identified modules. Here, we derive single framework that encompasses...
Limb immobilization and nonuse are well-known causes of corticomotor depression. While physical training can drive the recovery from nonuse-dependent effects, it remains unclear if is possible to gain access motor cortex in alternative ways, such as through imagery (MI) or action observation (AO). Transcranial magnetic stimulation was used study excitability hand left normal subjects immediately before after 10 h right arm immobilization. During immobilization, were requested either imagine...
In the last decades, introduction of robotic devices in fields such as industries, dangerous environments, and medicine has notably improved working practices. The availability a new generation humanoid robots for everyday's activities human populated environments can entail an even wider revolution. Indeed, not only domestic but also social behaviors will adapt to continuous interaction with completely kind agents. light this scenario, it becomes crucial design suited natural cooperation...
The purpose of this study was to analyze and compare the features center mass (CoM) control along anterior/posterior axis in young elderly subjects during sit-to-stand (STS). From a sitting position, seven healthy were asked stand up from chair under different experimental conditions (visual conditions: normal blindfolded; speed: as fast possible). Analysis results based upon concept "dynamic equilibrium area" (DEA), which turn identified dynamic limits balance. showed that both maximal CoM...
