We studied the effect of locomotor activity on the ultrastructure of cerebellar neurons, neurological disturbances, and survival rate in Krushinsky-Molodkina rats during the development of hemorrhagic induced by acoustic stress. In animals with high spontaneous locomotor activity, severe edema of cerebellar neurons (resulting in the destruction of surrounding structures) and swelling of the synapses (terminals of mossy fibers on granule cell dendrites) were observed. By contrast, the areas of intracerebral, subdural, and subarachnoid hemorrhages were lower in rats under conditions of forced rest.

This four-year longitudinal study investigated whether the cross-sectional and longitudinal associations of inflammation-related and neurodegenerative-related blood biomarkers with intrinsic capacity differ according to sex. The sample comprised 1117 older adults (<70 years, 63.8 % females) from the Multidomain Alzheimer's Prevention Trial (MAPT).

Reconfigurable modular robots can be used in application domains such as exploration, logistics, and outer space. The robots should be able to assemble and work as a single entity to perform a task that requires high throughput. Selecting an optimum assembly position with minimum distance traveled by robots in an obstacle surrounding the environment is challenging.

Humans exploit motor synergies for motor control; however, how they emerge during motor learning is not clearly understood. Few studies have dealt with the computational mechanism for generating synergies. Previously, optimal control generated synergistic motion for the upper limb; however, it has not yet been applied to the high-dimensional whole-body system.

The study of fish swimming behaviours and locomotion mechanisms holds significant scientific and engineering value. With the rapid advancements in artificial intelligence, a new method combining deep reinforcement learning (DRL) with computational fluid dynamics (CFD) has emerged and been applied to simulate the autonomous behavior of higher organisms like fish. However, the scale of this cross-disciplinary method is directly affected by the efficiency of the DRL model.
