Yes! 

Many signals have sometimes been thrown out at artifacts when actually they
are pointing to very interesting phenomena.


slow Cortical Potentials are one example.


I was informed that these were in many cases considered to be from body
movements that are irrelevant to the test and screened out as side noise.


 


Some new studies (and old) , have shown that many of these Slow Cortical
Potentials are indicators of interesting things and was like throwing the
baby out with the bathwater type analogy.


 


Go Light Ears!

The induced artifact from photic stim cable being close to an EEG lead is
very different from induced brainwaves.

The artifact is very spikey, whereas induced brainwaves are sinewave in
appearance.

this is cool, if the proposed method realy works
without opening up the skull.

keep in mind, that any electronic equipment,
near, or even in electrical contact with the body,
especially electronic pwm pulses, etc.
will create noise signal artefacts
that the eeg-amplifiers will pickup.

i don't discard the possibility though,
that something like this is theoretically possible.
