The elec­trical out­puts of the brain con­tain mas­sive amounts of infor­ma­tion that could be a pow­erful resource if we could fully tap into it. Our brain processes things we see before any con­scious recog­ni­tion of those images comes to bear. While we can already mea­sure elec­tro­mag­netic activity with EEGand MEG, both of these tech­niques are limited.

A new method devel­oped in the lab of physics pro­fessor Srinivas Sridhar could mea­sure the brain’s activity to, for example, detect threat­ening pat­terns in a drone pilot’s field of vision or track the brain’s response to neu­ro­log­ical drugs. Other pos­sible appli­ca­tions range from emo­tion analysis to neu­ro­mar­keting, whereby researchers examine the uncon­scious response to advertisements.
