Rock climbing is a fast growing adventure sport that sees use in summer camps, university programs, and commercial recreation across the world. Because of its challenging nature, rock climbing is often perceived to be a scary experience for newcomers; but it also seems to have a huge potential for self-growth. In this study we examine if the type of ground school instruction provided to climber...

An important step towards understanding the function of olivo-cerebellar climbing fibres must be to clarify what they signal. We suggest that climbing fibres projecting to paravermal cerebellum mediate highly integrated sensorimotor information derived from activity in spinal withdrawal reflex modules acting on single forelimb muscles. To test this hypothesis, cutaneous nociceptive receptive fi...

Climbing fiber discharges within the rat cerebellar cortex have been shown to display synchrony, especially for climbing fibers terminating in the same parasagittal bands. In addition, Purkinje cells which have the smallest rostrocaudal separation also seem to have the highest degree of synchrony. But this has so far only been investigated for distances down to 250 mum. In the present study, we...

it is well established that the active continuous recovery is preferred to passive recovery. but the active period of this recovery is long (20-60 minutes) and the intensity is not controlled. furthermore, most severe trial exercises need short-term active recovery for better performance so that the athletes can return more rapidly to their normal state and more desirable performance. however, ...

1 Motivation Many large terrestrial structures—towers, bridges, construction scaffolds—are sparse assemblies of rigid bars connected together at structural nodes. This is also true of many in-space structures such as antennae, solar panel supports, and space-station members. A long-term application of truss climbing robots is automated assembly, repair, and inspection of such truss-like structu...

In the adult cerebellum, the glutamate receptor delta2 subunit (GluRdelta2) is selectively targeted to the spines of the distal Purkinje cell dendrites, the spiny branchlets, that are innervated by the parallel fibers. Although GluRdelta2 has no known channel function, it is presumed to be involved in the formation and stabilization of these synapses. After block of electrical activity by tetro...

Climbing robots work in a special vertical environment and use mobility against gravity (Zhang, 2007). They are a special potential sub-group of mobile technology. In the recent 15 years, there have been considerable achievements in climbing robot research worldwide by exploring potential applications in hazardous and unmanned environments (Virk, 2005). The typical application of climbing robot...

In this review of research on climbing expertise, we focus on different measures of climbing performance, including spatiotemporal measures related to fluency and activity states (i.e., discrete actions), adopted by climbers for achieving overall performance goals of getting to the end of a route efficiently and safely. Currently, a broad range of variables have been reported, however, many of ...

Mice devoid of glial fibrillary acidic protein (GFAP), an intermediate filament protein specifically expressed in astrocytes, develop normally and do not show any detectable abnormalities in the anatomy of the brain. In the cerebellum, excitatory synaptic transmission from parallel fibers (PFs) or climbing fibers (CFs) to Purkinje cells is unaltered, and these synapses display normal short-term...

Most of the cerebellar Purkinje cells (PCs) of an adult animal are innervated individually by a single climbing fiber (CF) that forms strong excitatory synapses with the PCs. This one-to-one relationship between a PC and a CF is a consequence of a developmentally regulated regression of the innervation of PCs by CFs. We found that, in mice deficient in the type 1 metabotropic glutamate receptor...
