 Oszukiwanie, manipulowanie i stawianie niepokojącego pytania: czy twój mózg mówi ci prawdę? To oferuje między innymi wystawa "Mózg" w Pałacu Kultury i Nauki, ale główną atrakcją tej wystawy jest to, że można myślami, samymi myślami, kierować robotem. Idę sprawdzić, czy to naprawdę działa.

 Brawo! Lata! Wprawdzie nie śpiewa, ale lata - i to lata tak, jak Karolina - no, nie tak, jak sobie pomyśli, ale tak, jak skoncentruje się, żeby przekazać komputerowi tę komendę. Tak ten dron lata sterowany tylko i wyłącznie falami mózgowymi.
 No dobrze, udało się, przeżyłam, nie bolało, w dodatku cały eksperyment działał, więc jeśli ktoś chce przeżyć coś podobnego, może to zrobić weekendami, na wystawie Mózg w Pałacu Kultury i Nauki, do piątego lipca będzie można sobie założyć takie seksi wdzianko.
+**Tłumaczenie EN:**
+Tricking, manipulating and posing an unsetting question: is your brain
+telling you the truth? These, among others, are offered at the "Brain"
+exposition at Palace of Culture and Science (in Warsaw); the main
+attraction there, though, is the possibility of using your thoughts -
+and thoughts only - to control a robot. I'm going to see if it's
+really working.
+Electrodes on the head utilise these cables to send signal to the
+amplifier (?), from there the signal goes to the computer which
+displays brainwaves on the fly. It's an electroencephalogram - a
+brain's electric activity imprint. However, it's not only brain that's
+working using electricity in our body. Muscles use it as well; an eye
+is a electric dipole. These other signals can (and do) impose a strong
+(static?) noise on the signals coming from the brain to electrodes
+(placed) on the head. E.g. if one would exercise a comical muscle
+action now, the EEG underneath would basically get invisible. The
+signal coming from brain dissolved in this big noise. Yet, we can also
+measure the real brain electric activity imprint - and first of those
+electric thought tracks was the alpha wave, still called a Berger's
+wave; a graceful Alpha shows up, with the frequency probably around 10
+Hz. But we can measure it, the computer will show us the spectrum, one
+can see a beautiful 10 Hz sharp peak in the spectrum. But when we open
+our eyes, the alpha wave disappears, alongside the sharp 10Hz peak
+from the spectrum.
+Yes, we can see the 10 Hz is gone now. It's regular, resting-state
+EEG. This here is definitely brain activity. On
+that what comes from the brain to the surface of the head, we base the
+real Brain-Computer Interfaces. Because a Brain-Computer Interface is
+a device that enables one to communicate with the outside world
+without muscle activity. Waves such as these, coming from the brain,
+are used. It would be much easier to base on such interferences like
+wide smile, or, or rolling one's eyes, but that wouldn't be a
+Brain-Computer Interface. Many of the devices advertised and dubbed as
+simple Brain-Computer Interfaces work using such signals. We are now
+trying to get a read on something improbable - one of the first few
+physical correlates of the conscioussness process, process of
+concentrating in the history of humankind. What we can see on the
+display here, are consecutive, blinking letters. The computer will
+guess at which of them Karolina is concentrating, that is is thinking
+about one, not about another.
+It's not about at which one she is looking, but about which one is she
+thinking about. Preferably by counting the times a letter blinked -
+and here, on the EEG, we have marked consecutive ticks in which the
+given letters blinked. The computer knows when and which letter
+blinked and the task now is to focus attention on a particular letter,
+so the computer knows. On that basis the computer learns
+the specific shapes of the brainwaves corresponding to focusing
+attention - so called Evoked Potentials (EP's). And, after such a
+calibration, computer will be able to anticipate what would happen
+when Karolina focuses on a particular, on a particular letter or on a
+particular button. Computer takes that data and transmits it to the
+robot with a camera that is riding through a labyrinth. It looks like
+a toy, matter of fact it is a toy, that robot with camera, but now
+imagine, that this EEG cap is placed on a patient with a
+neurodegenerative disease that turned off his or hers ability of
+controlling any muscles, any kind of contacting the outside world - a
+robot like this could secure his or her telepresence and therefore
+could provide the contact with the outside world.
+Um, on the screen here I have four buttons tagged as:
+left, forward, right, backward. And crazy scientists here tell me that
+if I just focus and stare at, e.g. the backward button, the drone will
+actually fly backward.
+Congratulations! It is flying! It doesn't sing, though, but it flies.
+And it flies like Karolina, well, not as she thinks, but it flies as
+she focuses her attention to tell the computer the command. Yes, the
+drone flies controlled exclusively by brainwaves.
+Okay, we've succeeded, I managed to live through, it didn't hurt and,
+in addition, the whole experiment worked, so if someone would like to
+experience something similar, one can do it during weekends, at the
+"Brain" exposition at Palace of Culture and Science (in Warsaw). Up to
+the 5th of July one can wear such a sexy cap there.
