Unresponsive wakefulness syndrome: a new name for the vegetative state or apallic syndrome
BackgroundSome patients awaken from coma (that is, open the eyes) but remain unresponsive (that is, only showing reflex movements without response to command). This syndrome has been coinedExpand
Stochastic resonance and sensory information processing: a tutorial and review of application
OBJECTIVE To review the stochastic resonance phenomena observed in sensory systems and to describe how a random process ('noise') added to a subthreshold stimulus can enhance sensory informationExpand
Brain Function and Effects of Shift Work: Implications for Clinical Neuropharmacology
Night or shift work is to a relevant extent unavoidable, suits a growing preference for flexibility and is predicted to spread. However, a significant percentage of shift workers report discomfort orExpand
Magnetically recorded oscillatory responses to luminance stimulation in man.
Fast-frequency (ca. 100-110 Hz) oscillatory potentials superimposed on waves N2 and P2 of conventional broad-band VEP were magnetically recorded in man from occipital locations in response toExpand
Adrenocorticotropin-related modulation of the human EEG and individual variability
During a 6-h period in resting conditions, the blood concentrations at rest of cortisol, glucose and the adrenocorticotropic hormone (ACTH) varied spontaneously within physiological ranges in eightExpand
Scalp-recorded oscillatory potentials evoked by transient pattern-reversal visual stimulation in man.
Replicable oscillatory potentials, time-locked to pattern stimuli (9.0 degrees central; counterphase reversal at 2.13 Hz) were dissociated from conventional, broad-band VEPs recorded in healthyExpand
Visual pursuit in the severe disorder of consciousness.
Visual pursuit is a key descriptor of the minimally conscious state (above 80% of cases). It is also observable in about 20% of subjects in vegetative state. Its reappearance after severe brainExpand
Phosphenes in low earth orbit: survey responses from 59 astronauts.
INTRODUCTION It has long been known that many people in space experience sudden phosphenes, or light flashes. Although it is clear that they are related to high-energy particles in the spaceExpand
Effects of scopolamine (0.25-0.75 mg i.m.) on the quantitative EEG and the neuropsychological status of healthy volunteers.
There has been clinical and experimental evidence that cholinergic compounds and precursors of choline are potentially useful in the treatment of dementia. Anticholinergic compounds have also beenExpand
Human flash-VEP and quantitative EEG are independently affected by acute scopolamine.
Scopolamine in acute intramuscular doses of 0.25-0.75 mg reduced the P2-N3 flash-VEP amplitude and, in the quantitative EEG, the 8.5-12.0 Hz power and total power in 8 healthy young male volunteers.Expand
