Research interest

The group has a general interest in non-invasively studying higher order human brain functions and in-vivo basic and applied research of endemic central nervous system disorders.

The lab is focused on

1, Human brain mapping of cognitive functions: language network and its lateralization; brain correlates of behavioral and psychological measures

2, Brain reward system: common biomarkers and pathomechanisms of different addictions (e.g. smoking, problematic internet use, obesity)

3, Traumatic brain injury: role of microbleeds; mechanisms of cerebrovascular functional disturbances; translation of results from animal studies to clinical practice

4, Parkinson’s disease (PD): early diagnosis; deep brain stimulation; neuroimaging based biomarkers of neurocognitive disorder in PD; neurostructural basis of anxiety in PD; brain functions of PD patients with good cognitive skills

5, Subcortical iron accumulation in healthy and diseased brains

6, Brain morphometric changes in migraine

7, Epilepsy research: identifying brain changes (focus) with advanced neuroimaging methods; association between hippocampal sclerosis, febrile seizure and temporal lobe epilepsy

Over the last 6 years we have built an arsenal of skills in scientific methods, including behavioral and psychological testing, statistics and different MR modalities that are useful for evaluating brain in-vivo. Our long term goal is to use advanced neuroimaging techniques to facilitate the better understanding of healthy brain and clinically relevant central nervous system disorders. The multidisciplinar nature of our staff (neuro physician, radiologist, informatics expert, biologist, physicist, radiographer, psychologist), advanced MR (1.5T and 3T) systems and wide range of MR compatible accessories significantly supports the research objectives of our group.

Clinical relevance

Using MRI for human brain mapping, our research group concentrates on understanding the normal functional anatomy of human brain and the brain correlates of human behavior, as well as those nervous system diseases, which are quite common in the modern society (addictions, traumatic brain injury, Parkinson’s disease, obesity), but their pathomechanisms are not entirely understood, and reliable biomarkers are missing. By identifying brain structures and changes underlying these conditions we may better understand their pathophysiology, anatomical background, clinical picture and therapeutical options.
