Previous studies have suggested that complex movements can be elicited by electrical stimulation of the motor cortex. Most recording studies in the motor cortex, however, have investigated the encoding of time-independent features of movement such as direction, velocity, position, or force. Here, we show that single motor cortical neurons encode temporally evolving movement trajectories and not...

The influence of oscillatory activity in the motor system on the generation of voluntary movement has been previously studied by revealing temporal coupling between voluntary movements and associated physiological or pathological tremor. The present study aims to investigate whether there is any temporal correlation between the onset of a rapid reactive movement and the action tremor at the wri...

We studied 10 subjects each with melancholic depression evidencing significant motor retardation (RM), Parkinson's disease (PD) with bradykinesia, and normal healthy controls (NC), matched closely for age and gender, on measurements of motor function and depression, and their performance of simple and complex ballistic movements. The simple movements involved the execution of 10 degrees, 20 deg...

photo-albums and video-clips are simple means for diagnosis of diverseneurologic disorders in children. most families either own or can borrow a still or video camera. even when a purchase is required, it is more costeffective than brain imaging as well as other sophisticated studies, and the family has something useful to show for expenditure. on the other hand many families have a photo-album...

Little is known of how reallocations time spent in different movement behaviors during preschool might relate to preschoolers’ fundamental skills (FMS), a key predictor later physical activity (PA). Thus, the aim this study was examine (a) whether school-time associated with their FMS and (b) effects on reallocating between PA sedentary behavior (SB). This cross-sectional study, using intervent...

We propose a model for memory-based movement of an individual. The dynamics are modeled by stochastic differential equation, coupled with eikonal whose potential depends on the individual’s memory and perception. Under simple periodic environment, we discover that both long short-term appropriate time scales essential producing expected migrations.

The cerebellum has long been thought to play a crucial role in the forming of graceful movements, and it is viewed as a set of modules, each of which can be added to a control system to improve smooth coordinated movement, with improvements continuing and improving over time. The present paper proposes a new feedback error learning scheme for tracing in motor control system. In the scheme, the ...

Elastic tissues in the human body can store and return mechanical energy passively, reducing the metabolic cost of cyclical movements. However, it is not clear whether humans prefer movement patterns that optimize this storage and return. We investigated the preferred movement pattern during a bouncing task for which non-invasive techniques can identify the resonant frequency, which is the leas...

Recognizing human actions from video has been a challenging problem in computer vision. Although human actions can be inferred from a wide range of data, it has been demonstrated that simple human actions can be inferred by tracking the movement of the head in 2D. This is a promising idea as detecting and tracking the head is expected to be simpler and faster because the head has lower shape va...
