Human neurocognitive laboratories

Facilities_EEG

 

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

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

The fourth laboratory uses a 32-electrode EEG-recording system from Brain Products with BrainVision recording software. This laboratory is mainly dedicated for measuring infants.

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).

Additional equipment include SOMNOMedics ambulatory polysomnography device, SMI portable eye-tracking set, breathing and electro dermal activity (EDA/GSR) sensors, etc. All the laboratories can be flexibly modified according to researchers' needs and requests.
