BACKGROUND Depersonalisation is a subjective experience of unreality and detachment from the self often accompanied by derealisation; the experience of the external world appearing to be strange or unreal. Feelings of unreality can be evoked by disorienting vestibular stimulation. OBJECTIVE To identify the prevalence of depersonalisation/derealisation… (More)
Walking onto a stationary sled previously experienced as moving induces locomotor aftereffects (LAE, or "broken escalator phenomenon"). This particular form of aftereffect can develop after a single adaptation trial and occurs despite subjects being fully aware that the sled will not move. Here, we investigate whether such strong LAE expression may relate… (More)
A catalogue of 231 Galactic supernova remnants (SNRs) is presented, and the selection effects applicable to the identification of remnants at radio wavelengths are discussed. In addition to missing low surface brightness remnants, small angular size – i.e. young but distant – remnants are also missing from the current catalogue of Galactic SNRs. Several… (More)
Please cite the following paper for the summary data from this catalogue: This catalogue of Galactic supernova remnants (SNRs) is an updated version of those presented in detail in Green (which is 20 more than in the previous version; 21 remnants have been added, and one object removed), with over fifteen hundred references in the detailed listings, plus… (More)
A revised catalogue of 274 Galactic supernova remnants (SNRs) is presented , along with some simple statistics of their parameters. It is shown that the remnants that have recently been identified are generally faint, as is expected from the selection effects that apply to the identification of remnants.
INTRODUCTION We investigated the effect of postural changes on various cardiovascular parameters across gender. Twenty-eight healthy subjects (16 male, 12 female) were observed at rest (supine) and subjected to 3 interventions; head-down tilt (HDT), HDT with lower body negative pressure (HDT+ LBNP at -30 mm Hg), and head-up tilt (HUT), each for 10 minutes… (More)
BACKGROUND Patients with vestibular disease have an increased rate of reporting symptoms of depersonalisation/derealisation (DD) and similar symptoms can be provoked in healthy subjects during caloric vestibular stimulation. OBJECTIVE To assess the relationship between DD symptoms in patients with peripheral vestibular disease and their ability to update… (More)
Unpleasant visual symptoms including oscillopsia and dizziness may occur when there is unexpected motion of the visual world across the subject's retina ("retinal slip") as in an acute spontaneous nystagmus or on head movement with an acute ophthalmoplegia. In contrast, subjects with chronic ocular dysmotility, e.g., congenital nystagmus or chronic… (More)
