EEG measurements


This is my brain teacher. And if it were my Facebook post, this would be definitely already enough to get about 100 likes and at least 20 comments. But here I probably still need to write something else.

That’s very sad that we had only one subject,  I wish we could at least compare our data with the eeg of a watermelon, for instance. How fast do vegetables react on visual stimuli? On aural stimuli? Did anybody study that? If not I’m already writing my phd application.

Technical part of the experiment was fun and it was quite easy. I love all this medical stuff, cute cap with electrodes and diods (might be useful as well for Halloween), needles, syringes.. Just the gel perfume could be a bit more pleasant.

Since we are lamers preparations took about 40 minutes, but should be faster of course. Then we just run the presentation (it was kindly given by Marko, so we didn’t have to write the stimuli), then we recorded the data, washed the dishes, and then it was done. I suppose that the whole thing with writing the presentation and scripts for analysis would be way more tricky and time consuming task, but unfortunately that was not part of the course.

That’s really sad that the course has ended, it was one of the best I’ve been taking in Aalto. I wish it could be longer.

Institute of occupational sleep

I think that’s really great, that there are some certain things you always can be sure about. Like Earth goes around Sun, engineers are lazy, managers are in a hurry, architects are always late. (And neuroscientists are snobs, btw)

So, my a bit late reflections on the excursion in the Institute of Occupational Helth.

It was a quiet surrealistic experience, actually. First of all, Institute of occupational health studies almost only sleep. I can see some kind of logic here: the better you sleep the better you (can) work. Even though I know a lot of architects who sleep perfectly well, but I strongly doubt you might like to live in their projects. These architects might be healthy, but this fact has nothing in common with their occupation then. And on the opposite, I’ve never seen a good architect who says he sleeps enough. I don’t try to argue with the fact that sleep is important and affects our brain capacity. But studying sleep as the main criterion of occupational health sounds as weird as that Labor Day is a holiday. I’d like to learn something from studies on how do different types of interiors, traditional and coworking office spaces, affect on our effectiveness, what are the effects of artificial lightening, materials, textures, colours, sounds and noises, how do fixed and flexible working schedules affect the results, studies about group work vs independent work, leadership, psychological climate in teams, etc. I suppose these research topics could be more relative to the contemporary working environment and occupational health.

Next, the building. Let me find a propper word.. Mm, terrible? No, I really wonder why people who are supposed to study occupational health have to work in that ugly depressive environment? In dark spaces somewhere under ground, without windows and normal lightening, with long corridors painted in weird colours, which are furthermore sometimes a bit of a maze, and staircases like from the horror movies? How do they manage to work there without falling into deep-deep-depression?! They definitely have some secret knowledge they don’t share with us.

And finally, the research. I’m not from the field and know nothing very little about science and scientific research. But what’s the point in studying obvious things? During several months they were running research on men in army, collecting eeg data, analysing it, and all this to find what? To come up with the idea that people after physical loads and high stresses need more rest. Really? Really?! Very surprising. I would never guess. That sounds like “two years scientists were studying water in Baltic sea and  finally came up with the conclusion that it is wet”.

Don’t you know why does he need a gear wheel?
