Human neurocognitive laboratories



The EEG laboratories with separate control/observation rooms are located at Department of Psychology (Building Y33, ground floor).

Two laboratories have high density 128-electrode EEG-recording systems (EGI, Electrical Geodesics Inc.) with NetStation software. Individual sensor locations coordinates can be recorded using EGI Geodesic Photogrammetry System (GPS) or Polhemus Fastrak system.

The third laboratory uses a 32-electrode EEG-recording system from Brain Products with BrainVision recording software. The system can be also used with a Static Charge Sensitive Bed (SCSB) for EEG-recording during sleep in sleep research.

For the experiment control and presentation of stimuli E-Prime software (Psychology Software Tools Inc.), MatLab, and Experiment Builder (SR-research) are used. The laboratories have equipment for experimental design with auditory, visual and somatosensory stimuli.

Brain data are analysed using, in addition to traditional peak-based analyses, temporal and spatial principal component analyses (PCA), independent component analyses (ICA), current source density analyses, distributed and discrete source modelling, as well as time-frequency analyses. The programs used include BESA Research, BrainVision Analyzer, BrainVoyager QX, EEGLAB.

Eye-Link 1000 eye tracker system (SR-research) is used both for traditional eye movement studies as well as for synchronous recording with EEG.

Behavioural labs include sound attenuated testing rooms for studying psychophysical responses and cognitive processes with behavioral methods, including audiometry, standard psychological and neuropsychological test batteries as well as a variety of experimental approaches (including computerized tests).
