There’s a cool new paper on brain-to-brain interfaces, and I’m sure it will be misinterpreted in the media, just like every other paper of this genre. :)
There have been a couple of demonstrations of brain-to-brain interfaces before, and I’ve written about one of the previous papers in Finnish. The idea of BBI is that information about one participant’s brain state is read (typically using EEG), and then the brain state of another participant is manipulated, typically using TMS. At least in the press, these demonstrations are often termed as “telepathy” or “mind-reading”, and illustrated by images from Star Trek, X-Men or just people in tinfoil hats. Often the implications of these studies is posed as a question: will we soon be able to communicate with each other directly, without language? Will all our brains be connected together to form a giant common consciousness?
Aalto Brain Centre (ABC) organised yesterday a panel discussion to answer frequently asked questions about magnetoencephalography (MEG), a brain research method that is based on detecting the minute magnetic fields that brain activity generates. The panel was livestreamed, and the stream is now available online, and embedded below.
Kävimme esittelemässä Koneen säätiön rahoittamaa Social eMotions -projektiamme Oulussa, OuDance-festivaalilla. Kerroimme Jarkko Lehmuksen kanssa projektin tavoitteista ja siitä, mitä olemme tähän mennessä tehneet. Tiivistetysti: tutkimme tunteita kehollisina, sosiaalisina ja dynaamisina ilmiöinä. Videolla Jarkko ja Johanna Nuutinen demonstroivat tutkimusta varten luotua liikemateriaalia, lisäksi näytämme pari liikedata-animaatiota ja kerromme muutenkin projektin etenemisestä. Esittelimme tutkimusta Oulun kulttuuritalo Valven aulassa juuri ennen illan tanssiesityksiä.
After 10-year hiatus, I attended the Rhythm Perception and Production Workshop (RPPW), that this time was organised in Amsterdam. Since the last time, this conference series has changed a lot: the range of topics and approaches was huge, spanning from animal rhythmic abilities to gait, from Parkinson’s to language, from music and dance to rowing, with lots of neuroscience papers presented.

This picture depicts the relative timing of the pairs’ words. In the absence of any influence from the partner, the distribution would follow the red dashed line. Instead, the distribution is strongly concentrated on 180 degrees, which means the partners are in anti-phase entrainment – the words of one occur close to half way between the words of the other.
Now that we have recorded the approximately 450MB of movement data, it’s time to start processing and analysing it, and getting it ready for the next stages of the project. This, and probably the next couple of posts are about movement data: in this post I’ll explain briefly how optical motion capture works, and in the next ones what we can do with the data.

What a day! Yesterday we completed an important phase in the project: we have now recorded the movement data we are going to use in the next phases. This phase posed challenges for everyone in the project, as the artistic team, Jarkko and Johanna, had to create a choreography that could then be performed in different emotional scenarios, and then perfect those different scenarios to make them into convincing short stories, where the dynamic, social emotional processes are conveyed through body movements alone. The scientific team (me, Klaus and Maija) were racking our brains trying to figure out which combinations of emotions we should include (and crucially, which ones we could exclude), trying to make sure we have enough and correct data for the following phases (kinematic analysis, movement synthesis, and perceptual experiments).
