Our research group is a part of the Department of Neurobiology and Biophysics at the Institute of Biosciences.
Our group investigates human brain responses that may serve as potential biomarkers for various neurological and psychiatric disorders. We aim to determine how different states (such as alertness, activity level, and hormone levels), the nature of the task being performed, and the properties of the presented stimuli affect brain activity. We use electroencephalography (EEG) to assess the brain’s electrical activity at rest and during the presentation of various external stimuli. Additionally, we employ behavioural and subjective evaluation tests.
In our EEG studies, we apply classical event-related potential (ERP) methodologies (such as P300, P50, Go/NoGo, MMN). Still, we focus primarily on the brain's ability to engage with external stimulation, as reflected in steady-state responses (SSRs). We investigate how different stimuli (auditory, visual, somatosensory), their variations, and other factors (gender, dominant hand, fatigue, personality traits, etc.) modulate the parameters of SSRs. This knowledge is essential for understanding the processes occurring in the brain and their alterations in various disorders. Only by identifying the modulating factors can we ensure objective data collection and evaluation, which is crucial when using brain responses as biomarkers in clinical practice.
