[Eeglablist] [EXTERNAL] Re: Inquiry: Tool for measuring transient oscillatory events in continuous EEG

[Brian Harvey]

Thanks Cedric,

I have been reading and playing with this toolbox; however, I remain a bit confused on how this can convey information about individual events contributing to a clustered "micro-state" if at all. There is the "backfit microstate map to EEG" and this provides some quantifications of the microstates, but it is limited.  For example, I desire a way to verify that a "solution" map is reflecting the transient of interest. (i.e. mark the EEG record where the start and stop of the microstate events that are contributing to that particular solution.

Anyone out there with experience using this toolbox?

Thanks all in advance,
Brian

Hi Brian,

EEGLAB microstate plugin maybe?
https://urldefense.com/v3/__https://pubmed.ncbi.nlm.nih.gov/37697212/__;!!Mih3wA!B4yJhEtVblY9ZsZGsPASIS9k8gz_ZTstoScAuu7qwdwdXKoDXB9jb7dWO2IleSL8tqGYb2k3HvmYY5MlP-8sifKW8Q$

I am curious to hear more about this as well.

Cheers,
Cedric Cannard

I am hoping that I am not alone in the community and some tools already exist to investigate such types of events (like sleep spindles but, during wakefulness). I am uncertain if images translate well through this email list so a link below will bring up an image example of such an EEG record (120 sec snippet) - Note the transient events are in the high delta-low theta frequencies. I have ideas on how to estimate these features but always try to avoid re-inventing wheels, when possible, especially if published or pressure tested.
