[Eeglablist] Cognitive Neuroscience Group Study

[Abbas Braina Live]

Hello Jazmin.

It is an interesting observation, however, I can't recall clearly the
reason behind this. Perhaps you should ask the same on NeuroTechX community
forum. They have a huge network of researchers, scientists and engineers
working on bio-signals. I hope you would be able to find your answer there.
As a humble request, I would like to remain posted by you, so that I myself
might learn the reason behind this behaviour.

Warm regards,
