Marilyn Monroe-triggered Brain-Machine-Interface and the Dream-Recorder

Wissenschaftler haben ein Gehirn-Computer-Interface entwickelt, das auf Bildern von Marilyn Monroe basiert. Klingt abgefahrener, als es tatsächlich ist: Bislang griffen Interfaces auf Brain-Basis (hach!) vor allem eindeutige Richtungssignale (hoch, runter, links, rechts) ab, hier machen sie dasselbe mit den neuronalen Mustern, die von einigen Promis (Marilyn, Josh Brolin, Jennifer Aniston) hervorgerufen werden, im Grunde also dasselbe Prinzip.

Trotzdem: „Marilyn Monroe-triggered Brain-Machine-Interface“ wollte ich schon immer mal schreiben, tolles Dings.

Deep in your brain there are probably several thousand neurons that will respond only to the sight of Lady Gaga. Several thousand others probably only crackle to the sight of Justin Bieber. It might be nice to reassign those neurons to loftier thoughts. For now, though, neurology can’t help you. What neurology can do for you (if you’re up for a little invasive brain surgery) is let you use those Gaga and Bieber neurons to control a computer.

In a flash of mad genius, Koch and his colleagues wondered if people could use biofeedback to control the strength of these neurons. They interviewed twelve patients, and in each case they identified four celebrities who triggered particularly strong responses from their individual neurons. Then they superimposed two of those celebrities–in one case, Josh Brolin and Marylyn Monroe–on a computer screen.

In other Brainfuck-News wollen Wissenschaftler Träume aufzeichnen. Dazu nehmen sie obiges Phänomen (Neuronen, die bei bestimmten Bildern feuern [zum Beispiel bei Marilyn]), basteln dazu eine Datenbank und können dann anhand dieser Datenbank das Bilderfeuerwerk im Hirn beim Träumen aufzeichnen. Befindet sich natürlich alles noch im Anfangsstadium.

Writing in the journal Nature, researchers said they have developed a system capable of recording higher-level brain activity. "We would like to read people's dreams," says the lead scientist Dr Moran Cerf. […]

Dr Cerf makes his bold claim based on an initial study that he says suggests that the activity of individual brain cells, or neurons, are associated with specific objects or concepts. He found, for example, that when a volunteer was thinking of Marilyn Monroe, a particular neuron lit up.

So by observing which brain cell lit up and when, Dr Cerf says he was effectively able to "read the subjects' minds". He admits that there is a very long way to go before this simple observation can be translated into a device to record dreams - a "dream catcher". But he thinks it is a possibility - and he said he would like to try.
