Recent advances in functional magnetic resonance imaging (fMRI) have been used to reconstruct cognitive states based on brain activity evoked by sensory or cognitive stimuli. To date, such decoding paradigms were mostly used for visual modalities. On the other hand, reconstructing functional brain activity in motor areas was primarily achieved through more invasive electrophysiological techniqu...

The bioorganic basis of plant movement in two plant systems is described in this article: the circadian rhythmic leaf movement known as nyctinasty and trap movement in the Venus flytrap. The bioactive substances responsible for plant movement, the chemical mechanism of the rhythm, and studies on the key protein controlling nyctinasty are presented. The nyctinastic leaf movement is induced by a ...

BACKGROUND Hyperactivity is one of the core symptoms in attention deficit hyperactivity disorder (ADHD). However, it remains unclear in which way the motor system itself and its development are affected by the disorder. Movement-related potentials (MRP) can separate different stages of movement execution, from the programming of a movement to motor post-processing and memory traces. Pre-movemen...

objective the purpose of this study was to determine the prevalence and the most common risk factors of motor developmental delay in infants. materials & methods following ethical approval, a study was carried out on the prevalence and risk factors of infants with motor developmental delay. the first stage was conducted through a cross-sectional study to determine the prevalence of motor develo...

In motor learning, our brain uses movement errors to adjust planning of future movements. This process has traditionally been studied by examining how motor planning is adjusted in response to visuomotor or dynamic perturbations. Here, I show that the learning strategy can be better identified from the statistics of movements made in the absence of perturbations. The strategy identified this wa...

Motor learning in unimanual and bimanual planar reaching movements has been intensively investigated. Although distinct theoretical frameworks have been proposed for each of these reaching movements, the relationship between these movements remains unclear. In particular, the generalization of motor learning effects (transfer of learning effects) between unimanual and bimanual movements has yet...

motor imagery is the ability to imagine performing a movement without any action. the time a movement is mentally rehearsed highly correlates with the actual time of motor action. in this study, the effect of voluntary changes in imagery speed on the duration of the actual performance and learning a complex unfamiliar skill, and also the difference between the effects of real-time and fast imag...

What is it about movement in cells that commands our atten-tion? What biologist has not enjoyed turning a microscope on a cell, almost any cell, really, and watching all the commo-tion? When vesicles, mitochondria, chloroplasts, nuclei, or chromosomes move, we are being treated to an elegant, easily observable manifestation of molecular events. Decades of effort to understand intracellular move...

Motoneurons establish a critical link between the CNS and muscles. If motoneurons do not develop correctly, they cannot form the required connections, resulting in movement defects or paralysis. Compromised development can also lead to degeneration because the motoneuron is not set up to function properly. Little is known, however, regarding the mechanisms that control vertebrate motoneuron dev...

Recent studies suggest that a night of sleep may play a similar functional role following motor imagery (MI) practice. Here we examined whether offline gains following MI of a finger tapping sequence depends on the degree of complexity of the motor sequence, and whether this improvement differentially affects the individual transitions of the motor-sequence pattern being learned. The data revea...
