I am working with Dr. Bradley Postle on applications of Transcranial Magnetic Stimulation (TMS) in studying working memory function. TMS temporarily alters neural activity in a focused region of the brain using a reversible electric disturbance induced by a strong magnetic field. By having subjects perform tasks of spatial memory, I hope to use this technology, combined with electroencephalography, to clarify the functions of the various brain areas, specifically prefrontal cortex in various aspects of working memory.
