Inter-individual differences in cognitive performance are based on an efficient use of task-related brain resources. However, little is known yet on how these differences might be reflected on resting-state brain networks. Here we used Magnetoencephalography resting-state recordings to assess the relationship between a behavioral measurement of verbal working memory and functional connectivity ...

Subjective sleepiness is part of the system controlling the decision to go to sleep in humans. Extended periods of waking lead to increased sleepiness, as well as to changes in cortical electroencephalogram (EEG) during waking. We investigated the association of sleepiness and awake EEG spectra during 40 h of wakefulness using multi-electrode EEG recordings for full coverage of the scalp. We fo...

Mechanical stimulation is critical for bone architecture and bone mass. The aim of this study was to examine the effects of mechanical loads applied to the knee. The specific question was whether loads applied to the tibial epiphysis would enhance bone formation in the tibial diaphysis. In C57/BL/6 mice, loads of 0.5 N were applied for 3 min per day for 3 days at 5, 10, or 15 Hz. Bone samples w...

electromagnetic field (emf) radiation affects cellular and brain chemistry and function, resulting in deleterious effects such as free radicals formation, impaired dna repair, reduced melatonin and blood brain barrier protection, and defects on learning and memory and other higher brain functions. in this paper the effects of low frequency emf of 50- and 217 hz, ranges often associated with com...
