The instant you hear a cellphone pack , your brain reacts in a unique way – if the ringtone matches that of your own speech sound .
Anja Royeof the University of Leipzig in Germany and colleagues record the text - alert tones of 12 volunteers , then play them all the tones , at the same mass and in a random order , while recording their neural activity via scalp electrode .
In the first trial , Tennessean watched a tone down , subtitle pic while listen to the note . In the next trial there was no film to distract the unpaid worker , but they were told to press a button when they try their own ringtone . In the final trial , they were asked to pick out an assign ringtone belonging to another participant .
As you might gestate , genius areas linked to audition and memory retrieval light up when player learn their own ringtone or the one they were assigned . However , after just 40 msec , more neurons were fighting when volunteers heard their own ringtone than someone else ’s , even if this was the one they were assigned ( The Journal of Neuroscience , DOI : 10.1523 / jneurosci.1113 - 10.2010 ) .
Roye says this propose that our brains store “ template ” for our own ringtones , provide it to signalise quickly between intimate and unfamiliar tincture .
