The parietal cortex receives both visual- and motor-related information and is believed to be one of the sites of visuo-motor coordination. This study for the first time characterizes integration of visual and motor information in activity of neurons of parietal area 5 during locomotion under conditions that require visuo-motor coordination. The activity of neurons was recorded in cats during w...

The paper discusses the state-of-the-art of locomotion systems for ground mobile robots comprising tracks. Tracked locomotion, due to large contact surface with ground, is particularly suitable tackling soft, yielding, and irregular terrains, but characterized by lower speed energy efficiency than wheeled obstacle-climbing capability legged locomotion. Therefore, in recent years academic indust...

Introduction: Effects of stress on nervous system activity and development are well defined. In the present study, the effects of maternal stress on dopamine-related behavior in the offspring were studied. Methods: Female pregnant Wistar rats (200 g) were randomly exposed to the noise pollution stress (125 db) for 14 days (5 min/day). The time of exposure was random in order to avoid adaptat...

Muscle activity occurring during human locomotion can be accounted for by five basic temporal activation patterns in a variety of locomotion conditions. Here, we examined how these activation patterns interact with muscle activity required for a voluntary movement. Subjects produced a voluntary movement during locomotion, and we examined the resulting kinematics, kinetics, and EMG activity in 1...

This thesis presents a novel locomotion technique, called legless locomotion, for convex-bodied legged robots. The motivation for studying legless locomotion stems from the mobile robot recovery problem, stated simply as what should a robot do when trapped? Legless locomotion is the technique of locomotion for a legged robot which has no leg-ground contact, but can use the swinging legs to exci...

Caenorhabditis elegans nematodes are broadly used to investigate the impact of environmental factors on animal physiology and behavior. Here, C. with internalized paramagnetic nanoparticles were placed inside a magnetic field (MF) explore its effects locomotion. We hypothesized that combined external MF affect elegans’ locomotion machinery. To test our hypothesis, we adult fed bacteria mixed 1 ...

Multifunctional motoneurons and muscles, which are active during forward and backward locomotion are ubiquitous in animal models. However, studies in the nematode Caenorhabditis elegans suggest that some locomotor motoneurons are necessary only for forward locomotion (dorsal B-motoneurons, DB), while others (dorsal A-motoneurons, DA) are necessary only for backward locomotion. We tested this hy...

Contact inhibition of locomotion (CIL) occurs when a cell stops migrating in a particular direction upon contact with another cell. Many cancer cells show Contact inhibition of locomotion when contacting one another but display contact-unimpeded migration following collision with noncancer cells. Here we review current understanding of Contact inhibition of locomotion, from Abercrombie's histor...
