conclusions these open-label data show trends toward normalization of eeg and concomitant clinical improvement using magnetic stimulation for ptsd. results of the 21 patients who initiated therapy, 16 completed treatment. clinical improvements on the pcl-m were seen in these 16 patients, with an average pre-treatment score of 54.9 and post-treatment score of 31.8 (p < 0.001). in addition, relat...

Orgasm is a subjective experience accompanied by involuntary muscle contractions. We hypothesized that orgasm in women would be distinguishable by frequency analysis of a perineal muscle-derived signal. Rectal pressure, an index of perineal muscle activity, was measured continuously in 23 healthy women during different sexual tasks: receiving clitoral stimulation, imitation of orgasm, and attem...

Symptoms of Major Depressive Disorder (MDD) are hypothesized to arise from dysfunction in brain networks linking the limbic system and cortical regions. Alterations in brain functional cortical connectivity in resting-state networks have been detected with functional imaging techniques, but neurophysiologic connectivity measures have not been systematically examined. We used weighted network an...

In this study, it was aimed to find out whether electroencephalographic (EEG) frequency bands can be used distinguish people with obstructive sleep apnea (OSA) from those who do not have it. 11842 different cases taken 121 patients suffering OSA were combined the case study of 30-person control group without apnea. Apneas highlighted at respiration-record channels and EEG records which are conc...

Our recent event-related potential (ERP) studies showed that phase-locked electrophysiological activities mediate both early emotional sharing and late cognitive evaluation during empathy for pain. However, whether non-phase-locked neural oscillations are involved in empathic responses remains unknown. To investigate the functional role of non-phase-locked theta (3-8 Hz) and alpha (9-14 Hz) osc...

The cortical processing of consciously perceived and unperceived somatosensory stimuli is thought to be identical during the first 100-120 ms after stimulus onset. Thereafter, the electrophysiological correlates of conscious perception have been shown to be reflected in the N1 component of the evoked response as well as in later (>200 ms) nonstimulus-locked gamma-band (28-50 Hz) oscillatory act...

OBJECTIVE The purpose of this study was to identify the regions of the brain associated with recurrent nocturnal chronic hypoxic episodes in patients with untreated obstructive sleep apnea syndrome (OSAS) using low-resolution electromagnetic tomography (LORETA) and quantitative electroencephalography (QEEG). METHODS Nocturnal polysomnograph (NPSG) and subsequent morning electroencephalograph ...

Physical properties of visual stimuli affect electrophysiological markers of perception. One important stimulus property is spatial frequency (SF). Therefore, we studied the influence of SF on human alpha (8-13 Hz) and gamma (>30 Hz) electroencephalographic (EEG) responses in a choice reaction task. Since real world images contain multiple SFs, an SF mixture was also examined. Event related pot...

Many behavioral measures of visual perception fluctuate continually in a rhythmic manner, reflecting the influence of endogenous brain oscillations, particularly theta (∼4-7 Hz) and alpha (∼8-12 Hz) rhythms [1-3]. However, it is unclear whether these oscillations are unique to vision or whether auditory performance also oscillates [4, 5]. Several studies report no oscillatory modulation in audi...
