While the prospect of EEG technology being widely used in gaming and VR—predicted to be only around 20 years away—will thrill gamers, the truly exciting possibility for scientists and ...

EEG has previously been used to study dementia, but only in small numbers of patients and using a multi-channel EEG which requires multiple electrodes placed over the scalp and long measurement times.

EEG measurements are made non-invasively through the scalp, and they are relatively limited in terms of what they show about where in the brain activity has increased or decreased at any given moment.

E-tattoos adhered to participants' heads and successfully recorded brain activity for a full day, whereas EEG electrodes started to loosen after six hours. Once measurements were completed ...
