چکیده
|
Social interactions fill our everyday life and put strong demands on our brain function. however,the possibilities for studying the brain basis of social interaction are still technically limited,and even modern brain imaging studies of social cognition typically monitor just one participant at a time. we present here a novel method to connect and synchronize two faraway neuromagnetometers. with this method,two participants at two separate sites can interact with each other through a stable real-time audio connection with minimal delay and jitter. the magnetoencephalographic (meg) and audio recordings of both laboratories are accurately synchronized for offline analysis. the concept can be extended to connecting multiple meg devices around the world. as a proof of concept of the meg-to-meg link,we report the results of time-sensitive recordings of cortical evoked responses to sounds delivered at laboratories separated by 5 km. © 2012 baess,zhdanov,mandel,parkkonen,hirvenkari,mäkelä,jousmäki and hari.
