Hypothesis on the Influence of Solar and Terrestrial Electromagnetic Fields on the Formation of Psychotypes

Abstract This article presents a hypothesis that electromagnetic fields (EMF) from the Sun and Earth, acting during the critical window of embryonic neurogenesis, play a determining role in the formation of stable human psychotypes. The core idea is that external EMFs influence the direction and structure of axonal growth in key subcortical brain regions, leading to long-lasting neurobehavioral patterns. The paper identifies candidate EMF-sensitive cells and describes mechanisms such as electrotropism, gene expression modulation, and cytoskeletal organization that may underlie this effect. This model offers a biophysical explanation for individual psychological differences and provides a new perspective on the phenomenon of astrological correlations and psychological compatibility.
