Elimination of cerebellar granule cells early during postnatal development produces abnormal neural organization that retains immature characteristics in the adult, including innervation of each Purkinje cell by multiple climbing fibers from the inferior olive. To elucidate mechanisms underlying development of the olivocerebellar projection, we studied light-microscopic morphology of single oli...

OBJECTIVE To examine using surface electromyography whether stair climbing with abdominal hollowing (AH) is better at facilitating local trunk muscle activity than stair climbing without AH. METHODS Twenty healthy men with no history of low back pain participated in the study. Surface electrodes were attached to the multifidus (MF), lumbar erector spinae, thoracic erector spinae, transverse a...

The "negrito" and African "pygmy" phenotypes are predominately exhibited by hunter-gatherers living in rainforest habitats. Foraging within such habitats is associated with a unique set of locomotor behaviors, most notably habitual vertical climbing during the pursuit of honey, fruit, and game. When performed frequently, this behavior is expected to correlate with developmentally plastic skelet...

A three dimensional force measurement system was integrated in a climbing hold. The force measurement system consisted of three orthogonally mounted platform load cells. Data acquisition and power supply of the load cells was performed by a wireless data acquisition system ViFDAQ. Data was transferred by ViFDAQ to a nearby laptop by a wireless Bluetooth connection. Measurements were done during...

The goal of modular robots is to achieve versatility in the field, while satisfying any number of traditional robot tasks. We chose the task of traversing terrain by climbing, and present various methods of climbing with modular robots. In particular, we focus on the tasks of climbing across a horizontal rope, climbing up a vertical rope, and climbing up stairs using the Superbot modular robot....

This paper presents a family of climbing robots that are using a track-wheel mechanism for locomotion mechanism. There are three robots: High speed vertical climbing robot, Flexible caterpillar robot, and Multi-linked climbing robot. The high speed vertical climbing robot uses suction pads to be attached on walls, and the robot has an advantage of high climbing speed of 14 m/min. The flexible c...

Whether early hominins were adept tree climbers is unclear. Although some researchers have argued that bipedality maladapts the hominin skeleton for climbing, others have argued that early hominin fossils display an amalgamation of features consistent with both locomotor strategies. Although chimpanzees have featured prominently in these arguments, there are no published data on the kinematics ...

Climbing over chasms larger than step size is vital to fruit flies, since foraging and mating are achieved while walking. Flies avoid futile climbing attempts by processing parallax-motion vision to estimate gap width. To identify neuronal substrates of climbing control, we screened a large collection of fly lines with temporarily inactivated neuronal populations in a novel high-throughput assa...

Interactive systems have been used successfully in sports to assist people in achieving their performance goals, however, we believe that some aspects are often overlooked. In this paper we focus on rock climbing and we examine existing work on climbing from varying fields, including sports science, psychology, and climbing literary works, in order to identify recurring motivational themes. In ...

Juveniles of three species of Hawaiian gobiid fishes climb waterfalls during migration to adult habitats using two kinematically distinct patterns: Awaous guamensis and Lentipes concolor use rapid, intermittent bouts of axial undulation (‘powerbursts’), whereas Sicyopterus stimpsoni inches up waterfalls by alternately attaching oral and pelvic suckers to the substrate. Despite the differing kin...
