The electroencephalograph (EEG) source imaging (ESI) method is a non-invasive that provides high temporal resolution of brain electrical activity on the cortex. However, because accuracy EEG often affected by unwanted signals such as noise or other source-irrelevant signals, results ESI are incongruous with real sources activities. This study presents novel (WPESI) based wavelet packet transfor...

People who report objects moving in their presence, unusual sounds, glows around other people, and multiple sensed presences but do not meet the criteria for psychiatric disorders have been shown to exhibit electrical anomalies over the right temporal lobes. This article reports the striking quantitative electroencephalography, sLORETA results, and experimental elicitation of similar subjective...

EEG/MEG source localization based on a "distributed solution" is severely underdetermined, because the number of sources is much larger than the number of measurements. In particular, this makes the solution strongly affected by sensor noise. A new way to constrain the problem is presented. By using the anatomical basis of spherical harmonics (or spherical splines) instead of single dipoles the...
