The PLAE lab (Psychophysiology of Learning, Attention, & Expertise) provides equipment for state-of-the-art two-person studies. The dyadic setups can include:
Dyadic infrastructure is developed in PLAE lab in collaboration with the CELLS group, PI Docent Ilona Södervik, UH; the Electromagnetics in Health Technology group, PI asst. prof. Ilkka Laakso, Aalto University; and prof. Riikka Möttönen, Cognitive Science, UH. We also collaborate extensively with Cognitive Brain Research Unit, Medical Faculty, UH.
For recording, we use two Tobii Pro Spectrum 600Hz desktop eyetrackers, plus synchronised Shimmer GSR+ 3 biosignal sensors, and two 20 channel EEG amplifiers. The lab space is designed to control ambient sound and light, so we can conduct sensitive measurements of, e.g. pupillometry.
For brain stimulation, we use transcranial direct/alternating current stimulation (tDCS/tACS), using two unpaired Neuroelectrics Starstim tACS/EEG devices with 20 channel amplifiers, or a pair of linked Neuroconn bipolar devices for dyadic stimulations. In our brain stimulation work, we also use Transcranial Magnetic Stimulation (TMS) in the project led by Dr. Andrei Rodionov, sited at CBRU.
