This study examined the visual and motor components of pseudoneglect as expressed on horizontal bisection tasks. Ten participants were tested on bisection of lines and elliptical shapes and judgement of pretransected lines. Results showed the same magnitude of leftward error on all three tasks, in contrast to previous findings for patients with visuospatial(More)
INTRODUCTION Mental impairments, including deterioration of mood and cognitive performance, are known to occur during isolation and space missions, but have been insufficiently investigated. Appropriate countermeasures are required, such as exercise, which is known to prevent mood disorders for prolonged space and isolation missions. Based on the(More)
BACKGROUND This study investigates the effects of seasonality and altitude on sleep in extreme Antarctic conditions. METHODS During summer and winter periods, 24 h of actimetric recordings were obtained at two different research stations, Dumont d'Urville (sea level altitude) and Concordia (corrected altitude 12,467 ft or 3800 m). RESULTS During(More)
At altitudes above 2,500 m, ventilation in healthy subjects commonly shows periodic breathing: an oscillatory behavior with alternating periods of hyperventilation followed by central apneas or hypopneas (1–3). Although an increase in altitude is correlated with an increase in the occurrence of periodic breathing (1, 4), the magnitude, the time course, and(More)
Normal participants display a leftward bias when bisecting horizontal lines. It has been proposed that bisection errors can be affected by representational biases. We investigated the possibility that this effect could also be explained as the result of perceptual cueing. Participants bisected horizontal lines with identical arrows arranged around the(More)
STUDY OBJECTIVES Exposure to hypoxia elevates chemosensitivity, which can lead to periodic breathing. Exercise impacts gas exchange, altering chemosensitivity; however, interactions between sleep, exercise and chronic hypoxic exposure have not been examined. This study investigated whether exercise exacerbates sleep-related periodic breathing in hypoxia. (More)
