Ictal source localization

Sorry for the inconvenience, I'm a neurologist at an epilepsy center and I'm trying to do a research with EEG ictal source localization, and even reading all the tutorials I'm having difficulty doing it. If anyone can give me a hand on how to proceed. Thank you very much for your attention.

I am not an expert, but I am interested in learning more from the neurologist's perspective. You can email me at alain.de.cheveigne@ens.fr.

Please see with Alain indeed but if you could please post specific issues here, that would be helpful to the community as well. Maybe get started with trying to get your data loaded into Brainstorm?

Hi @alain @leoallves

The Brainstorm just released a new workshop for SEEG data analysis.

You can find all the data and the walkthrough on this page: https://neuroimage.usc.edu/brainstorm/WorkshopParkCity2024

It can be a good starting point for what you are looking for.

Thanks! This is very helpful.

I don't know if it is feasible, but the following would be nice to have in the dataset:

  • a bit more background information about the patient, recording, etc.
  • a bit more data (for example a few interictal spikes)
  • some data paired with speech (active and/or passive) to see if it's possible to locate eloquent cortex from the SEEG recordings.

early onset of interictal spike:

@alain, thank you for the feedback.

A new tutorial with more material and data will be released from this workshop.
However, I'm not sure if the data has any task related to speech.
