Welcome to the FieldTrip website

FieldTrip is the MATLAB software toolbox for MEG, EEG and iEEG analysis, which is released free of charge as open source software under the GNU general public license. FieldTrip is developed by members and collaborators of the Donders Institute for Brain, Cognition and Behaviour at Radboud University, Nijmegen, the Netherlands.

Registration for the 2024 FieldTrip MEG/EEG toolkit course is now open!

Please cite the reference paper when you have used FieldTrip in your study.

The Neuro – Irv and Helga Cooper Foundation Open Science Prizes 2024

The Montreal Neurological Institute-Hospital has launched the 2024 edition for the Open Science Prizes! These prestigious awards celebrate groundbreaking projects that promote Open Science in the field of neuroscience. Check out the details on how you can apply.

Last year the Brain Imaging Data Structure (BIDS) steering group was awarded the International Prize, perhaps this year your Open Science project gets selected!

We will present a tutorial at the Workshop on Intracranial Recordings in humans, Epilepsy, DBS (WIRED) at ICM in Paris from 13th to the 15th of March 2024. The FieldTrip tutorial will happen in the afternoon of the 13th.

To attend the hands-on tutorials, participants will have to register here and bring their own laptops.

From about 2009 we used a locally hosted Bugzilla server as “issue tracker” to maintain and distribute to-do lists and supports the follow-up communication between developers and users. Since about 2016 we moved on to GitHub for project management and issue tracking. We would occasionally still look up some old Bugzilla discussion regarding features, code design choices and bugs.

However, due to resource limitations and security concerns we decided to discontinue the Bugzilla server. As of now, https://bugzilla.fieldtriptoolbox.org contains a read-only archived copy of the bug reports and discussions. All links from the website and from the email archive to bugs on Bugzilla should still work, so the details of past work are not lost.

EEG100 Image Competition - $500 USD Prize - Closing 29th February 2024

One hundred years ago Hans Berger undertook the first ever recording of electrical activity from a human brain. The discovery of a “brain script”, offered to revolutionise our understanding of mind and brain…

As we celebrate a century of this ground-breaking moment for the neurosciences, the EEG100 consortium invites you to submit creative visual images that provide a homage to the legacy of Berger’s discovery and/or present a glimpse into the future possibilities EEG holds. The winning visual will be used by the EEG100 consortium throughout 2024 as part of the centenary year celebrations. The work will for example be included in a scientific commentary article and presented at various conferences (with full acknowledgment).

This competition is open to everyone – whether you’re a hobbyist, a professional artist/designer, or simply a neuroscientist with a creative side. We have no specific demands on visual style or content; we’re looking for originality and creativity – surprise us! We do however ask that you avoid designs like a brain with ‘100’ superimposed on it. Ideally the work would adapt well to various formats, from print to digital display, but we welcome all forms of submissions (image, film, animation etc)! Please be aware that by submitting your design, you agree to release the image to the public domain under a CC license of your choice.

The winner will be determined by vote within the EEG100 consortium based on originality, relevance, and overall visual impact of the submissions. The winning creator will be awarded a $500 USD gift voucher.

You may submit any common file format (like .jpg, .png, .pdf for images or .mp4 for video) but if your design is chosen, we will ask you to supply your artwork in a production ready format. Please email your submission to century.of.eeg@gmail.com with the subject title “#EEG100 Image Competition” by the end of 29th February 2024 (on the last time zone on earth!).

You will receive a confirmation email upon successful submission.

Decisions will be announced by the end of March 2024.

We are coming up to the 100-year anniversary of the discovery of human EEG.

In celebration of this seminal moment for human neuroscience, we are asking the FieldTrip, the EEG, and the neuroscience community at large, to document the impact this discovery has had on our understanding of the brain and to share thoughts on the short, medium, and long-term future of human non-invasive scalp EEG through this online survey. Importantly, this survey will also help in defining our collective perspectives on future research priorities.

I hope you will be able to spare the 10-15 minutes it will take to complete the survey and make your views heard about the past and future of EEG.

Thank you for your time.

From May 22-26 we will host our annual MEG/EEG toolkit course at the Donders in Nijmegen. In this 5-day course we will teach you advanced MEG and EEG data analysis skills. Pre-processing, frequency analysis, source reconstruction, connectivity analysis and various statistical methods will be covered. The toolkit consists of a number of lectures, followed by hands-on sessions in which you will be tutored through the analysis of a MEG data set using the FieldTrip toolbox. Furthermore, you have the opportunity to work on your own data with the guidance of experienced tutors.

Preregistration is now open, see here.
