the following abstract of interest. Granted, it's only a sample of
one, but it's an indication, at least, that some folks are giving the
issue some thought. I've kept an eye out for follow-up studies, but
have found none, so far. I'll certainly pipe in if I find something
> EEG AND SPECT DATA OF A SELECTED SUBJECT DURING PSI TASKS: THE DISCOVERY OF A NEUROPHYSIOLOGICAL CORRELATE
>>CHERYL H. ALEXANDER, MICHAEL A. PERSINGER, WILLIAM G. ROLL, AND DAVID L. WEBSTER
>>ABSTRACT: Electroencephalograph (EEG) and Single-Photon Emission Computerized Tomography (SPECT) data were collected from Sean Harribance, a well documented psychic who has previously
>participated in laboratory research, while he was engaged in psi tasks. This data was independently collected from 2 different laboratories during 1997.
>The primary goal of the EEG data collection was to determine the dominant electrocortical activity and its location while Sean participated in psi tasks. EEG data were collected from Sean in the following 5 psi tasks: 2 psychic readings from photographs, 2 runs of card guessing with standard ESP cards using the down through method, and 1 remote viewing trial. After removing any artifacts, the data for each condition were then spectrally averaged and topographic brain maps were computed which showed that while Sean was engaged in psi tasks, alpha was dominant bilaterally in the paraoccipital region, with alpha power being strongest in the right parietal lobe at electrode placement P4. A lack of alpha activity was seen in the frontal and temporal lobes.
> For subsequent data analysis, Dr. Robert Thatcher at Applied Neuroscience Laboratory in Redington Shores, Florida, edited and removed any artifacts from the raw EEG data collected from Sean during an eyes-closed baseline. He then analyzed the data for EEG coherence, phase, amplitude differences, and relative power, and compared these measures to the data in his Lifespan Reference EEG Database using the appropriate age-matched group. Results show deviations from the reference database that are primarily bilateral, involving the occipital, temporal, and frontal regions. Sub-optimal neural function is indicated, especially in the frontal and temporal cortical regions.
> Two Tc-99m SPECT ECD brain scans were completed with Sean in order to contrast a baseline resting condition with a psi task condition. The results indicate the areas of Sean's brain that were active while he was in the psi task condition and the baseline resting condition. The most pronounced finding was increased uptake of the tracer, relative to cerebellar uptake, in the paracentral lobule and in the superior parietal lobule of the right hemisphere only during the psi task condition. A mild decrease of function in the frontal,
>temporal, and thalamus regions is suggested by the lack of uptake of tracer in these areas during both conditions.
>The consistency of the results across laboratories, equipment, experimenters, and research protocols suggests the existence of a neurophysiological correlate which is stable across both time and conditions. It is hypothesized that the parietal cortex is activated while Sean is engaged in psi tasks as this part of the brain is attributed with visual search attention via the posterior attention network. Also, it is speculated that Sean's brain may be more highly developed or may function at a higher level in the parietal cortex to
>compensate for a lack of activity or sub-optimal neural function in the frontal and temporal cortical regions. The data presented is specific for Sean and may not be applicable to others. Further research with other selected subjects is needed in order to determine if these results can be replicated between subjects.
