Our group investigates human brain responses that are potential biomarkers for various neurological and psychiatric disorders. We aim to determine how different states (such as alertness, activity level, hormone levels in the body, etc.), the nature of the task being performed, and the properties of presented stimuli affect brain activity. We use the electroencephalography (EEG) method to assess the brain’s electrical activity both at rest and during the presentation of various external sensory stimuli. Additionally, we employ behavioral and subjective evaluation tests.
In our EEG studies, we apply classical event-related potential (ERP) methodologies (such as P300, P50, Go/NoGo, MMN), but we focus primarily on the brain's ability to engage with external stimulation, known as 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 especially important 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.
