Los Angeles, CA, USA: December 5th, 2024
Register Now: seats are very limited!
This full-day workshop will take place at the University of Southern California on Dec 5th, immediately prior to the American Epilepsy Society Meeting (AES 2024). This session will highlight Brainstorm's unique features for multimodal scalp electrophysiology data analysis (EEG/MEG), with a second focus on intracranial recordings (iEEG).
Participants are invited to their personal laptops for a unique hands-on experience (data will be provided).

Requirements
In order to make the workshop as efficient as possible, we ask all the attendees to: download, install and test the software and download the workshop dataset on their laptops prior to the workshop.
We highly recommend bringing an external mouse on the day of the workshop. Most of the manipulations are done with the mouse, and some involve an intense use of the scrolling operation.
Installing Brainstorm
Please read carefully the following instructions on:
preparing your laptop for the training
Workshop dataset
In this workshop, we will be working on a multimodal data. In the morning session we will work on combined EEG/MEG data sets. In the afternoon we will use SEEG dataset recorded at the Epilepsy Monitoring Unit at UTHealth Houston.
Morning Session (EEG and MEG Analysis)
The workshop dataset for this session is a pre-processed version of the dataset used in the Brainstorm tutorial on median nerve stimulation. It consists of simultaneous EEG and MEG recordings during a median nerve stimulation experiment (right arm). A full description of the dataset can be found here.
Once you have successfully installed and tested Brainstorm (see previous section), proceed to download the dataset for the workshop.
- Download the tutorial dataset (1.5 GB):
Unzip the downloaded file on your desktop: it will create a new folder named workshopLaxMorning
- Final check: after following the steps above, you should have 3 folders on your desktop:
brainstorm3: the software folder, containing the source code and the compiled executable
brainstorm_db: your Brainstorm database (which should be empty for now)
workshopLaxMorning.zip: Dataset used during the workshop session
Afternoon Session (SEEG Analysis)
In this session of the workshop, we will be working on a SEEG dataset recorded at the Epilepsy Monitoring Unit at UTHealth Houston.
The data is distributed as raw and pre-processed data.
raw data is located in the file workshopLaxAfternoon_raw.zip which contains raw SEEG recordings (in EDF format), T1 MRI and CT scan (both in NIfTI format). The raw SEEG recordings correspond to:
- Two files containing seizure onset:
- Seizure onset with Low-voltage-fast-activity
- Seizure with Ictal repetitive spiking
- One file with interictal spike, and
- One file containing baseline recordings
- Two files containing seizure onset:
pre-processed data is located in the file workshopLaxAfternoon_precomputed.zip, which contains a Brainstorm protocol with the raw data already pre-processed.
Once you have successfully installed and tested Brainstorm (see previous section), proceed to download the data to be used in the workshop.
Download the raw data (500 MB):
Unzip the downloaded raw data on your desktop: it will create a new folder named workshopLaxAfternoon_raw
Download the pre-processed data (3 GB). Do not unzip this file:
- Final check: after following the steps above, you should have 3 folders on your desktop:
brainstorm3: the software folder, containing the source code and the compiled executable
brainstorm_db: your Brainstorm database (which should be empty for now)
