Scientific topicsResearch Staff Methods Projects Publications
The scientific activity of the department develops in three main directions, including studies of (1) brain neuroelectric mechanisms of cognitive processes and brain states, (2) regulation of posture and movements, and (3) visual-manual coordination and learning.
Research is conducted on humans with a focus on development and aging, normal and pathological conditions, individual characteristics, and environmental effects.
Specific topics and goals include research on: (1) neurophysiologic correlates of higher cognitive functions such as attention, memory, implicit and explicit learning; (2) neurophysiologic correlates of brain states and states of consciousness – sleep, wakefulness, internal and external concentration; (3) the stance and postural and motor coordination while maintaining static and dynamic balance of the body during quiet stance, stance under different environmental conditions, sensory conflict caused by stimulation (visual, auditory, proprioceptive); (4) physiology and pathophysiology of eye movements; (5) visual-manual coordination and adaptation; (6) learning and brain plasticity; (7) cognitive functions, motor functions, stance, postural control, and adaptation in the course of development and aging, and in pathological conditions (attention deficit / hyperactivity disorder, dyslexia, Parkinson's disease, vestibular disorders, diabetes, glaucoma, etc.); (8) individual differences (gender, psychological profiles, etc.), (9) physiology and neurophysiology of mental and physical stress (work stress, sports); (10) development and implementation of new advanced methods for registration and analysis of neuroelectric brain potentials, oscillations and their synchronization, oculographic and electromyographic potentials, and biomechanical indices.
