In this week we had two EEG studies in Aalto Behavioral Laboratory (ABL) at Otaniemi. Both studies were carried out with same test protocol. The test protocol included different variations of reaction times (sound and visual inputs). The test subject was sitting in a room which was sealed from outside noise and electrical currents. The test lasted about twelve minutes and included different sets of inputs for testing reaction times. It was actually really interesting to take part of preparing the EEG electrodes and see from the screen how different movements caused the EEG to change. For instance, how closing eyes or use of the face muscles caused changes.
