TDE-207XX Lead for dry EEG electrodes / hard to snap in

zfmeng

Hello!
We bought the TDE-207XX Lead for dry EEG electrodes. But it's really difficult to connect with dry electrodes. After connecting with electrodes, could the electrode be taken down to change a new one?
By the way, could Ultra-Mark Ⅳ be used for emotion detection?
Thank you very much.

Did you use the suggestions posted on this page?

The spikey electrodes are particularly difficult to insert. To attach them to the headband: (1) Loop the metal wire part of the connector around the neck of the electrode. (2) Press down the plastic part to snap it into place around the neck of the electrode.

re: emotion detection, the larger term for this is "affective BCI". Yes any EEG cap, electrodes or headset could be used.

Thank you for your explanation. I'd like to try your suggestions.
About the affective BCI, how to get the scalp projection image from EEG data?
Thank you very much.

Affective BCI is a huge field, choose your focus and look at relevant papers.
