Background and aims: Sound is one of the most effective exogenous factors affecting brain processing mechanisms, including attention that affecting human error and occupational accidents. The purpose of this study was to investigate the effect of sound frequency on noise annoiance, selective attention and human response time. Methods: This research is an interventional study that was con...
We describe the unilateral occurrence of 14 and 6 Hz positive bursts in successive EEGs in a 25-year-old woman following surgical resection of a left parietal arteriovenous malformation which had caused a left parieto-temporal intracerebral hematoma. This is only the second reported case of unilateral 14 and 6 Hz positive bursts. This could represent either a normal pattern seen unilaterally be...
background: in previous investigations, it has been clarified that electromagnetic fields (elf) can cause some changes in cellular behavior. the aim of this prospective study was to investigate the effect of magnetic field (mf) on human sperm parameters of motility, morphology, and viability. materials and methods: semen samples were collected from 12 fertile men, and were allowed to liquefy fo...
introduction increase in alpha band is observed when blood perfusion in frontal area of head decreases. the present study evaluated some changes in the alpha band particularly, alpha-1 of frontal and central areas of the head, when several areas were exposed simultaneously to magnetic field. materials and methods five points of head (f3, f4, cz, t3, and t4) of twenty healthy male participants w...
Introduction: Neural stimulation is a promising new technology for the treatment of medically-intractable seizures. Transcranial Magnetic Stimulation (TMS) is a simple, non-invasive, low cost technique which is widely used in neurophysiology. In a few studies that have been performed at different frequencies the therapeutic effects of this technique were not obvious. Repetition of low frequen...
