Motor-Free Contractility in Active Gels [PDF]
Physical Review Letters, 2020 Animal cells form contractile structures to promote various functions, from cell motility to cell division. Force generation in these structures is often due to molecular motors such as myosin that require polar substrates for their function. Here, we propose a motor-free mechanism that can generate contraction in biopolymer networks without the need ...

“Fitness and Fatness” in Children and Adolescents: An Italian Cross-Sectional Study
Children, 2021 Children with obesity tend to have lower level of physical activity compared to non-obese peers. In fact, sedentary behaviors are prevalent in obese children causing difficulties to perform motor tasks and engaging in sport activities. This, in turn, has

Attention-dependent modulation of neural activity in primary sensorimotor cortex [PDF]
, 2013 Although motor tasks at most times do not require much attention, there are findings that attention can alter neuronal activity not only in higher motor areas but also within the primary sensorimotor cortex.

Motor Activity Improves Temporal Expectancy [PDF]
PLOS ONE, 2015 Certain brain areas involved in interval timing are also important in motor activity. This raises the possibility that motor activity might influence interval timing. To test this hypothesis, we assessed interval timing in healthy adults following different types of training.

Metachronal propagation of motor activity
Frontiers in Bioscience, 2013 A diverse array of biomechanical systems has evolved to satisfy locomotor requirements (reptation, swimming, walking, etc.) and in all cases, successful behabior achievement requires the integrated functioning of various segments, to ensure the appropriate positioning of the different body regions.

THE MOTOR ACTIVITY OF THE VENAE CAVAE [PDF]
JAMA: The Journal of the American Medical Association, 1922 The question as to whether the establishment of a definite peripheral resistance requires active variations in the size of the venous blood-bed has been discussed repeatedly. In general, it may be stated that the resistance encountered by the arterial blood in its passage through the vascular system depends on: ( a ) the size of the arteriocapillary ...
