Eeg

I'll take your EEG.

Davide Valeriani, senior research officer at University of Essex’s BCI-NE Lab, is using an electroencephalogram (EEG)-based BCI to tap into the unconscious minds of people as they make decisions. “Everyone who makes decisions wears the EEG cap, which is part of a BCI, a tool to help measure EEG activity ... it measures electrical activity to gather patterns associated with confident or non-confident decisions,” says Valeriani.

Indeed, while many philosophers of language in the 20th century proposed that we think in sentence-like strings of language, use of brain imaging technology like electroencephalography (EEG) and electrocorticography (ECoG) has since revealed that thinking more probably happens in a complex combination of images and associations.
