Research on human navigation by psychologists and neuroscientists has come mainly from
a limited range of environments and participants inhabiting western countries. By contrast …

Given that sleep deprivation studies consistently show that short sleep causes
neurocognitive deficits, the effects of insufficient sleep on brain health and cognition are of …

Most animals require sleep, and sleep loss induces serious pathophysiological
consequences, including death. Previous experimental approaches for investigating sleep …

Study objectives Country or regional differences in sleep duration are well-known, but few
large-scale studies have specifically evaluated sleep variability, either across the work …

Importance Sleep disturbances and clinical sleep disorders are associated with all-cause
dementia and neurodegenerative conditions, but it remains unclear how longitudinal …

Objective Short sleep and insomnia are each associated with a greater risk of age-related
disease, which suggests that insufficient sleep may accelerate biological aging. We examine …

Recent evidence suggests that greater reliance on GPS-assisted devices is associated with
poorer navigation ability. Studies have also shown that video gaming may be associated …

Short sleep is held to cause poorer brain health, but is short sleep associated with higher
rates of brain structural decline? Analysing 8,153 longitudinal MRIs from 3,893 healthy …

Watchkeeping schedules are essential for maintaining submarine operations, but come with
human risk factors including, disrupted sleep, circadian misalignment, and cognitive deficits …

Despite extensive research on navigation, it remains unclear which features of an
environment predict how difficult it will be to navigate. We analysed 478,170 trajectories from …
