This paper describes a psychological experiment which was conducted to evaluate the influence of haptic feedback on the perception of self-motion in virtual reality. Participants were asked to estimate the angle of one turn made during a passive visual navigation. Sometimes, during the turn, a haptic feedback was sent to the dominant hand of the participants. This haptic feedback consisted in r...

The impressive precision of mammalian limb movements relies on internal feedback pathways that convey information about ongoing motor output to cerebellar circuits. The spino-cerebellar tracts (SCT) in the cervical, thoracic and lumbar spinal cord have long been considered canonical neural substrates for the conveyance of internal feedback signals. Here we consider the distinct features of an i...

The electrosensory lateral line lobe (ELL) of weakly electric fish is the only nucleus that receives direct input from peripheral electroreceptor afferents. This review summarises the neurotransmitters, receptors and second messengers identified in the intrinsic circuitry of the ELL and the extrinsic descending direct and indirect feedback pathways, as revealed by recent in vitro and in vivo st...

The cumulative harvest pressure exerted by recreational anglers can be intense in some locations. Sustainable management and conservation of inland fisheries requires an understanding the spatial ecology fish-angler interactions (e.g., direct, indirect, feedback). Advancement towards this goal study complex interdependencies human natural systems, which achieved, part, looking beyond wetted con...

this study aimed at identifying components of the household health costs.this study was a qualitative research conducted in two main phases. the first phase consisted of interviews with sample households selected in eight provinces of iran. they were to identify components of the household health costs. in the second phase, components were determined as direct, indirect and intangible based on ...

background: multiple sclerosis is a common and chronic neurologic disorder. this disorder imposes physical, economic, and psychosocial burden on individuals, their families and society. this study aims to analyze the costs of multiple sclerosis disease based on the severity of disability. methods: we performed a cross‑sectional cost of illness study. this study was conducted in 332 patients of ...

introduction: the restoration of endodontically treated teeth is a topic that has been studied extensively but it is still a challenge for dental practitioners. the aim of this study was to evaluate fracture resistance, fracture patterns and fracture location of endodontically treated human maxillary premolars restored with direct and indirect composite resin and ceramic restoration. methods: e...

conclusions accidents resulting in death, total disability and partial disability impose huge costs that are borne by society, and employers bear relatively low costs due to the health, treatment and welfare systems provided by society for the treatment and rehabilitation of injured workers and their families. also, the results of this study show that investment in the hse-ms is effective and a...
