Kinga Tóth, PhD
Research Associate
Kinga works on surgically removed human neocortical tissues from epileptic and non-epileptic patients. She studies the spontaneous synchronous population activity which is generated in the slice-preparations of these specimens. By applying electrophysiological and anatomical methods, she examines the role of perisomatic inhibition in generating physiological and pathological activities. CV
