                   Alterations in Imaginings and Suggestibility

                       During Brief Magnetic Field Exposures


                    by Christine F. DeSano and M. A. Persinger

                             at Laurentian University


                    originally in Perceptual Motor Skills, 1987

       --------------------------------------------------------------------


       Male and female subjects were exposed to alternating magnetic fields

       of 1 and  4  Hertz  which  were  applied  across  their mid-superior

       Temporal lobes.


       In addition, a green light was pulsed  in  phase  with  the magnetic

       field while the participant was instructed to imagine  an  encounter

       with an alien.


       --------------------------------------------------------------------


       Rostral (at nose  level)  to  the upper half of the ear, retractable

       arms were placed, each containing  a 25 CM (1 CM diameter) soft iron

       nail wrapped (1050 turns) with insulated wire (20 gauge).


       A function generator was used to drive the solenoids  with sine wave

       current at either 1 HZ or 4 HZ.


       Magnetic field intensity was about 15 GAUSS at the skull surface.


       Field strength measured at the temporal cortex was 2 GAUSS.


       Maximum field strength as measured at the level of the frontal lobes

       was 200 MGAUSS (a 10 factor decrease).


       At the level of the hippocampus, field strength was 500 MGAUSS.


       All subjects generated  elaborate imaginings when exposed to a green

       light flashing in sync with the driven solenoids.



                                      Page 1






       4 HZ field imaginings included a sensation of rising or floating.


       The end result  of  the  experiment was that hypnotic susceptibility

       may be increased following magnetic-field exposure but that the most

       effective frequency is different for each sex.


       The quantity of   imagery   generated   (particular   the   floating

       sensations) INCREASED if  the  person observed a light  flashing  in

       sync with a 4 HZ applied magnetic field.


       Most interesting of  all  was that the magnetic field strengths were

       MUCH LESS than those expected to occur in NATURAL SETTINGS.

       Vangard Notes..


             OMNI writer  Dennis  Stacy   did  an  article  on  Persinger's

             research in December of 1988 (I think).  It  relates  the  UFO

             encounter phenomen  and how it could quite possibly be INDUCED

             by alternating magnetic fields of relatively low intensity.


             As I remember the article, Persinger was using a football with

             multiple solenoids placed in  a  grid  and  supported over the

             skull.


             When the  helmet  was  driven  by a computer as  a  peripheral

             device (a  printer),  various  patterns  (characters) could be

             projected onto the brain of  the  subject  to  induce  various

             effects.


             If any of our KeelyNet associates come across this article, we

             would appreciate a copy or uploading of the text that we might

             annotate and included it in a text file.
