Róbert Bódizs, PhD
    Our scientific interests are mainly, but not exclusively related to sleep research, more specifically to the relationship between sleep, behavior and psychological phenomena. Sleep is an ancient component of the mammalian behavioral repertoire which has been being preserved in its original form during the course of evolution. According to our opinion sleep provides a perfect insight so as to understand human behavior. One of the defining characteristics of sleep is the widespread synchronization of individual neurons and networks, which leads to the appearance of specific low frequency EEG patterns. As synchronization needs connectivity, the neuroanatomical condition of efficient synchronization lies in intracortical and corticothalamic synaptic infrastructure. Stable individual differences in sleep-EEG are called individual fingerprints and are supposed to reflect functional neuroanatomy of underlying brain tissue. Based on this idea we focus our research on sleep-EEG correlates of aging, general and specific cognitive abilities, personality and of trait-like affective styles in normal and pathological conditions such as autism spectrum disorders and borderline personality disorder. The hitherto hidden aspects of the latter traits and conditions are being unraveled by newly developed quantitative EEG methods and the parallel use of volumetric MRI assessed brain morphology. We consider that sleep-EEG combined with brain morphology and complex psychological examination offers the appropriate multidisciplinary approach towards a more exhaustive understanding of the neurobiology of normal and pathological mental conditions. Besides significantly enriching our factual knowledge of the composite relationship between brain function, structure and behavior, this approach also hides expectedly multiple possibilities for developing new diagnostic tools in different psychiatric disease.
