Elevations of complex partial epileptic-like experiences during increased geomagnetic activity for women reporting "premenstrual syndrome"

Geophysical variables and behavior: XCVIII. Ambient geomagnetic activity and experiences of "memories": interactions with sex and implications for receptive psi experiences

During 96 nonsequential days over a 3-yr. period, a total of 53 men and 86 women were exposed only once for 30 min. to transcerebral, weak complex magnetic fields while they sat alone within a quiet chamber. They were asked to record the frequency of specific experiences after the exposure was completed. There was a significant interaction between sex and global geomagnetic activity for the incidence of experiences attributed to memories. Women reported more experiences attributed to "childhood memories" when geomagnetic activity was less than 20 nT, while men reported more of these experiences when the activity was more than 20 nT. Re-analyses of a database of "paranormal experiences" reported by 395 separate individuals over a 100-yr. period indicated that more men than women reported "precognitive experiences" on days the geomagnetic activity was above 20 nT while women reported such experiences if the geomagnetic activity was below 20 nT. These results suggest that these experiences, be they veridical or illusory, may be influenced by global geomagnetic activity that affect the neuroelectrical or neurochemical processes associated with memory consolidation or the attribution of the serial order of experiences during retrieval.

Geophysical variables and behavior: LXXXVI. Geomagnetic activity as a partial parturitional trigger--are male babies more affected than female babies?

The birth dates of 163 men and 245 women who were born between the years 1958 and 1969 were extracted from our data base for first-year university students. Daily aa values, measures of the amplitude of global geomagnetic activity, were obtained for the birthdays and for each of the seven days before and after the birthdays. Analyses of variance indicated no significant differences in the magnitudes of the geomagnetic activity during these 15 days; however, men were born when the geomagnetic activity was significantly higher than when the women were born. The effect, which was equivalent to a correlation coefficient of about .20, was largest for the day of birth and for the two or three days before birth. The means of the aa values for the day of birth and the day before birth for the men were about 7 nanoTesla higher than the values for the women.

Premenstrual syndromes: closing the 20th century chapters

The need to re-evaluate premenstrual syndromes became apparent in 1997-1998 and early 1999. The success stories of some symptomatic treatment modalities and more sophisticated studies of pathobiology chart the pathways for future progress: the shift from a descriptive diagnosis to diagnoses based on etiology, the recognition of diversified vulnerabilities and their expression in particular situations, and specific treatment modalities.
