ON THE SAME WAVELENGTH
crowd-sourcing neuroimaging research | interactive brain-art installations <<
How do our brains interact which each other and with the environment? What does it mean to be 'on the same wavelength' with another person? And: what are the conditions that may help us synchronize our brains?

I address these questions in a series of real-time interactive brain/art installations, developed with Matthias Oostrik and varying collaborators, such as Marina Abramovic. These installations use custom-software that collects, cross-correlates and visualizes participants' brain activity in real time. In addition to art projects, they are crowd-sourcing neuroscience experiments aimed at investigating what makes us 'click.' As such, the audience takes on the role of performer and scientific subject at once.

NEUROSCIENCE EXPERIMENT I: MEASURING THE MAGIC OF MUTUAL GAZE is an experiment/art installation/performance investigating neural synchrony between two people as a function of prolonged mutual gaze. Volunteers engage in silent mutual gaze while their brain activity is displayed in real time, giving insight into their evolving internal experience as well as moments of neural synchrony. Following Marina Abramovic' durational performance The Artist is Present (MoMA 2010), it investigates the transfer of energy between performer, public, and participant.

COMPATIBILITY RACER is a competitive, interactive brain-robotics installation. Participants are outfitted with EEG headsets, pair up, and sit facing each other on the “bull.” Exploring the underlying brain mechanisms of interpersonal communication through transportation, the “bull” moves as a direct result of increasingly shared brain activity. Conversely, movement slows or halts as a function of participants’ lack of (brainwave) alignment. Thus, the participants’ movement is literally fueled by successful communication and collaboration.

BRAINS MUTUAL WAVE MACHINE introduces a neurofeedback environment to questions about interaction: two people are immersed in an enclosed capsule, surrounded by an audio-visual environment that reflects and influences their brain synchronization.

INSIDE THE LAB, we use fMRI to ask whether the ability to predict a speaker's intentions might increase the similarity, or neural coupling, between a speaker and her listeners' brain activity, a possible index of enhanced mutual understanding. We find increased speaker-listener neural coupling in areas that have previously been implicated in (predictive) language processing (posterior superior temporal gyrus specifically).

PREDICTING AND PARSING LANGUAGE IN TIME AND SPACE
effects of prediction on sensory processing and language comprehension | working memory in language processing <<
How is it possible that it takes the brain only a few hundred milliseconds to know that a sentence like the grass was blue is strange?
Using MEG, we found that brain regions dedicated to low-level sensory analysis are sensitive to seemingly high-level language properties (syntax and lexical-semantics) as early as 100 ms after the presentation of a word. We propose a Sensory Hypothesis to explain this finding: Sensory cortices do not perform linguistic analysis; rather, they are sensitive to linguistic predictions that have been 'translated' into form features before the onset of a predicted word or syntactic category. We have tested this predictive account of rapid and efficient language processing in a series of MEG experiments.
