MEG–EEG REPORTING MEG–EEG reporting guidelines are not meant to represent rigid rules but general recommendations for reporting MEG–EEG results. They are intended for standard MEG–EEG recordings rather than for special procedures. When reporting on more specialized types of records, description of technical details should be more complete than in the case of standard recordings. The MEG–EEG rep...

There is not yet a formal definition of magnetoencephalography (MEG) spike. This study provides a parametric description and definition of clear-cut MEG spikes recorded simultaneously by MEG and depth electrodes (iEEG). A total number of 367 simultaneous MEG/iEEG spikes were selected for analysis. Distribution of morphologic spike parameters and detailed quantitative analysis of the basic morph...

An object oriented programming approach for the design of complex systems in hardware is presented. The paper describes how the usage of object oriented techniques resolves some major obstacles for systemon-chip design. The design of a 10 Mbit/s upstream cable modem is used as a driving example.

PURPOSE To investigate institutional and individual practices and attitudes in clinical magnetoencephalography (MEG) in the United States. METHODS An MEG Center Director Survey (20 questions) and an MEG Center Doctoral-Level Staff Survey (6 questions) were e-mailed to all clinically active MEG centers in the United States (21) in 2008. RESULTS Fifteen centers declared to be in operation an ...

INTRODUCTION Magnetoencephalography (MEG) measures magnetic fields generated by neuronal currents. MEG is complementary to EEG. Considerable body of evidence indicates that ictal MEG recordings can provide useful information for pre-surgical evaluation of epilepsy patients alongside the more established long-term ictal video-EEG. Ictal MEG is recorded in some epilepsy surgery centers. However, ...

a r t i c l e i n f o Keywords: Software and hardware quality assurance Airborne software and hardware Safety certification DO-178B DO-254 To ensure the safety of avionic systems, civil avionic software and hardware regulated by certification authorities must be certified based on applicable standards (e.g., DO-178B and DO-254). The overall safety integrity of an avi-onic system, comprising sof...

although response to intranasal steroid therapy has been reported in pa¬tients with allergic rhinitis, efficacy of some nasal steroids is noteworthy. this study was undertaken to evaluate the efficacy of a two-week course of fluticasone (flixonase) nasal spray vs. beclomethasone (beconase) nasal spray in patients with symptoms of allergic rhinitis referred to our clinic. this study reviewed six...

Although magnetoencephalography (MEG) and electroencephalography (EEG) have been available for decades, their relative merits are still debated. We examined regional differences in signal-to-noise-ratios (SNRs) of cortical sources in MEG and EEG. Data from four subjects were used to simulate focal and extended sources located on the cortical surface reconstructed from high-resolution magnetic r...

fMRI-constrained EEG/MEG source imaging can be a powerful tool in studying human brain functions with enhanced spatial and temporal resolutions. Recent studies on the combination of fMRI and EEG/MEG have suggested that fMRI prior information could be readily implemented by simply imposing different weighting factors to cortical sources overlapping with the fMRI activations. It has been also rep...
