Influence of TMS-Coil Position on the Lateralization of Phosphenes Elicited by Magnetic Stimulation of the Visual Cortex

This study examines the dependence of phosphene position in the visual field on the site of transcranial magnetic stimulation (TMS). We found a strong negative correlation between the x-coordinate of the phosphene position in the visual area and horizontal position of the stimulation coil. It demonstrates the presence of a stable relationship between phosphene lateralization and TMS coil displacement in the horizontal plane. Obtained results can be valuable for the development of brain-computer interfaces (BCIs) with direct feedback including virtual reality applications.
