NNL News

Mia Kellman and Alana Lieske each received "Top 5" poster awards at the MINDS Post-Baccalaureate Poster Symposium on June 13th!

Find the story featured on the MIDB Synapse/Newspage here. This was a wonderful event where post-bac research technicians in the neurosciences had a chance to present work, make new connections, and appreciate one another.

Name the TMS Robot Contest

Two NNL facilities dedicated to pediatric neuromodulation research have been established at the Masonic Institute for the Developing Brain. One of these labs includes a robotized TMS system, of which there are only a handful in the U.S. and 40 in the world! We invited the community to celebrate with us by sponsoring a “Name the TMS Robot Contest,” inspired by the Minnesota Department of Transportation’s annual Name a Snowplow contest. We've narrowed the name submissions to our top selections and invite you to vote now on your favorite name!

Welcoming Undergraduate Research Assistants

This Fall semester, we have two Undergraduate Research Assistants (RA) joining the NNL team: Adam Behun and Shreya Srinivasan! These RAs will soon be available to assist our lab users with data collection, entry, and analysis. Please join us in extending a warm welcome to them!

Coming Soon: NNL Website

The NNL is actively working on creating a distinct website to provide information for researchers and community members alike! Once launched, laboratory guidelines, documents, photos, and virtual tours will be accessible there. In the meantime, you can find additional information about our pediatric laboratories on the Neuromodulation Hub webpage on the MIDB website.

The Non-invasive Neuromodulation Laboratories (NNL) celebrated their 10th anniversary on Friday, January 10th over lunch at the Tea House, reflecting on a decade of research support and growth. Approximately 50 studies using non-invasive brain stimulation have been supported by the NNL since its establishment in December 2014. Last year over 532 experiment visits took place in the NNL, totalling more than 1,600 hours of data collection.
