Although there is converging experimental and clinical evidences suggesting that mental training with motor imagery can improve performance, it unclear how humans learn movements through despite the lack of sensory feedback from body environment. In a first experiment, we measured trial-by-trial decrease in durations executed (physical group) mentally simulated (motor-imagery group), by means on multiple-target arm-pointing task requiring high accuracy speed. Movement were significantly...
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)...
Several investigations suggest that actual and mental actions trigger similar neural substrates. Motor learning via physical practice results in long-term potentiation (LTP)-like plasticity processes, namely of M1 a temporary occlusion additional LTP-like plasticity. However, whether this neuroplasticity process contributes to improve motor performance through remains be determined. Here, we tested skill learning-dependent changes primary cortex (M1) excitability by means transcranial...
Key points While a consensus has now been reached on the effect of motor imagery (MI) – mental simulation an action cortical areas, less is known about its impact spinal structures. The current study, using H‐reflex conditioning paradigms, examined 20 min MI practice several mechanisms plantar flexor muscles. We observed modulations presynaptic circuitry while imagining, which was even more pronounced following acute session practice. suggested that small output generated during may reach...
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...
The brain has evolved an internal model of gravity to cope with life in the Earth's gravitational environment. How this benefits implementation skilled movement remained unsolved. One prevailing theory assumed that is used compensate for gravity's mechanical effects on body, such as maintain invariant motor trajectories. Alternatively, force could be purposely and efficiently planning execution voluntary movements, thereby resulting direction-depending kinematics. Here we experimentally...
Motor imagery (MI) is the mental simulation of movement, without corresponding muscle contraction. Whereas activation cortical motor areas during MI established, involvement spinal structures still under debate. We used original and complementary techniques to probe influence on structures. Amplitude motor-evoked potentials (MEPs), cervico-medullary-evoked (CMEPs), Hoffmann (H)-reflexes flexor carpi radialis (FCR) triceps surae muscles was measured in young, healthy subjects at rest MI....
Abstract Individuals with aphantasia report having difficulties or an inability to generate visual images of objects events. So far, there is no evidence showing that this condition also impacts the motor system and generation simulations. We probed neurophysiological marker during explicit implicit forms simulation, i.e. imagery action observation, respectively. tested a group individuals without any reported deficits (phantasics) as well self-reporting mentally simulate movements...
