All good things have to come to an end. Sadly, our recess week passed by so quickly and suddenly we are back to work. In Week 9, our team started our experiments for data collection. There are two different experiments to be done, the Functional Magnetic Resonance Imaging (fMRI) and Electroencephalography (EEG).
On Monday, we headed down to the Huajiachi Campus which is equipped with the fMRI facilities to conduct our experiments. Some of us thought that it would be very easy and relaxing to do the experiment since we only had to lie down but NOOOO. We are not allowed to move once the experiment commences, even a slight nod may ruin the experimental data! Also, not everyone is able to participate as a test subject. Being left-handed would mean that you are unable to participate in both EEG and fMRI due to differences in the dominant brain hemisphere.
Before the fMRI Experiments
As for the EEG experiments, we used Yuquan Campus’ Neuro Lab. The EEG experiments were unfortunately very long (~ 5HRs!!!!!!!). However, this was mostly because of the long preparation time needed. Before putting on the EEG cap, the test subject has to wash and blow dry his/her hair. After the cap is on, conductive gel has to be inserted between the scalp and the cap to reduce electrical impedance.
That’s all from me for Week 9! BYE!!!!!!
