3. June 4-8, 2012Space Weather Effects on Humans..., Moscow, Russia3  To study the relationships between geomagnetic activity (GMA) and meteorology factors and cerebral activity  Duration 2011 – 2015  Why geomagnetic activity and human brain?  A subset of the human population (10-15%) is a bona fide hypersensitive and predisposed to adverse health problems due to geomagnetic variations  Extremely high as well as extremely low values of GMA seem to affect the health status  Experimental studies support the hypothesis for a possible correlation between mental health and solar activity, i.e. correlations between geomagnetic intensity and  The number of persons admitted to a psychiatric hospital  The suicide attempts  The traffic accidents  The number of suicidal terroristic acts  The occurrence of acute neurological vascular accidents In order to demonstrate the potential correlations a large scale research, including hundreds or even thousands of subjects, has to be performed

4. June 4-8, 2012Space Weather Effects on Humans..., Moscow, Russia4  To study: The effects of GMA and meteorology on behavior of healthy volunteers; The effects of preliminary advertisement of possible magnetic storms on the wellbeing of health volunteers (well-being surveys); The link between geomagnetic activity and the occurrence of cerebral pathology; The lag, if any, between the time of manifestation of cerebral vascular accidents and the geomagnetic indexes; The relation between the cerebral vascular pathology (ischemic or hemorrhagic cerebral infarction) and the stages of magnetic storms, i.e. to confirm or reject the theory that during geomagnetic disturbances the microcirculation parameters of human brain may undergo rapid changes from increased coagulation (i.e. increased probability of thromboses) to decreased viscosity (i.e. increased probability of hemorrhages)
