Electromagnetic fields, such as those from mobile phones, alter regional cerebral blood flow and sleep and waking EEG
Usage of mobile phones is rapidly increasing, but there is limited data on the possible effects of electromagnetic field (EMF) exposure on brain physiology. We investigated the effect of EMF vs. shamExpand
Effect of age on the sleep EEG: slow-wave activity and spindle frequency activity in young and middle-aged men
The effect of age on sleep and the sleep EEG was investigated in middle-aged men (mean age: 62.0 years) and in young men (mean age: 22.4 years). Even though the older men reported a higher number ofExpand
A functional genetic variation of adenosine deaminase affects the duration and intensity of deep sleep in humans
Slow, rhythmic oscillations (<5 Hz) in the sleep electroencephalogram may be a sign of synaptic plasticity occurring during sleep. The oscillations, referred to as slow-wave activity (SWA), reflectExpand
A Genetic Variation in the Adenosine A2A Receptor Gene (ADORA2A) Contributes to Individual Sensitivity to Caffeine Effects on Sleep
Caffeine is the most widely used stimulant in Western countries. Some people voluntarily reduce caffeine consumption because it impairs the quality of their sleep. Studies in mice revealed that theExpand
Clinical and Physiological Consequences of Rapid Tryptophan Depletion
We review here the rapid tryptophan depletion (RTD) methodology and its controversial association with depressive relapse. RTD has been used over the past decade to deplete serotoninExpand
Pulsed radio frequency radiation affects cognitive performance and the waking electroencephalogram
We investigated the effects of radio frequency electromagnetic fields on brain physiology. Twenty-four healthy young men were exposed for 30 min to pulse-modulated or continuous-wave radio frequencyExpand
Age-dependent changes in sleep EEG topography
OBJECTIVE To assess age-related topographic changes in the sleep electroencephalogram (EEG). METHODS The sleep EEG records of young (mean age, 22.3 years) and middle-aged (mean age, 62.0 years)Expand
Pulsed radio‐frequency electromagnetic fields: dose‐dependent effects on sleep, the sleep EEG and cognitive performance
To establish a dose–response relationship between the strength of electromagnetic fields (EMF) and previously reported effects on the brain, we investigated the influence of EMF exposure by varyingExpand
Exposure to pulse‐modulated radio frequency electromagnetic fields affects regional cerebral blood flow
We investigated the effects of radio frequency electromagnetic fields (RF EMF) similar to those emitted by mobile phones on waking regional cerebral blood flow (rCBF) in 12 healthy young men. TwoExpand
Caffeine intake (200 mg) in the morning affects human sleep and EEG power spectra at night
Adenosine has been implicated in the physiological regulation of sleep propensity. The adenosine-receptor-antagonist, caffeine (100 mg), administered immediately prior to a nocturnal sleep episode,Expand
