The investigation of the static and dynamic features involved in the cognitive processes

The objective: to investigate cognitive processes in encoding, storing and processing of information.

Areas of research: color constancy, temporal discrimination of flashing stimuli, audio visual integration in temporal processing, the influence of attention and expectations on temporal discrimination of flashing stimuli, the influence of eye movement on processing of visual information, cognitive functions.

Methods: psychophysical experiments with visual and auditory stimulus, mathematical modeling, psychophysiological experiments.

Equipment: stimulus generation system ViSaGe (CRS), custom build LED lamps capable of creating different colour environments and stimuli with various timing profiles, multichannel maxwellian view system, eye tracking system RED250 (SMI), eyetracker for microsacade eye movement and image stabilization on retina DPI (Fourward), audiometer AD629 (Tomatis), spektroradiometer PR-680L (Photo Research), Physiological data acquisition systems MP150 (Biopac), MP36 (Biopac), functional near infrared optical brain imaging system FNIR100, behavioral experiment software E-Prime

Keywords: Colour perception, colour constancy, visual adaptation, subjective colours, temporal processes, eye movement, audiovisual interaction, cognitive functions.

Brain-computer interface research

The goal of this investigation is to investigate brain signals and develop methods that could be effective for Brain-Computer Interface (BCI). BCI is a fast-growing technology in which researchers aim to build a direct channel between the human brain and the computer. The BCI can lead to many applications especially for disabled persons. Most of these applications are related to disable persons in which they can help them in living as normal people.

Methods: psychophysiological experiments. Equipment: Physiological data acquisition systems MP150 (Biopac), MP36 (Biopac), Mobilab (G.tec), functional near infrared optical brain imaging system FNIR100, behavioral experiment software E-Prime.

Keywords: Brain computer interface (BCI), electroencephalography (EEG), P300 wave
