 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. Oszukiwanie, manipulowanie i stawianie niepokojącego pytania: czy twój mózg mówi ci prawdę?

 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.

 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. 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.

 +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.
