🥳 BIG NEWS for the lab! 🥳 I'm excited to join the Göttingen neuroscience community and the excellence cluster
@MBExC_de as a tenure-track group leader at the European Neuroscience Institute (ENI-G), where we will continue neural circuit research in a great research environment!

Have you ever wondered how memories are processed downstream of the #hippocampus and how this is affected by #Alzheimer's? We believe we may find some answers by riding all the way down the fornix to the mammillary body. Apply here for a #PhD with us: https://ovgu.b-ite.careers/56yvk

Excited to say that our paper on #hippocampus-accumbens projection #neurons and their role in spatial reward navigation and appetitive behaviours is now published in @naturecomms :
https://www.nature.com/articles/s41467-024-47361-x
Please see preprint thread for our main findings: https://neuromatch.social/@obarnstedt/110026426575610133

In addition to what we’ve shown in our preprint, we now also show that optogenetic silencing of the dorsal hippocampus-accumbens pathway leads to reduced appetitive licking near the reward zone. Plus, a lot more analysis and statistics in the supplement!

We are now also sharing all our calcium trace and behavioural data with the community: https://zenodo.org/doi/10.5281/zenodo.10698564, along with Jupyter notebooks reproducing all our main figures based on this data: https://github.com/obarnstedt/dHPC-NAc – please write me if you have any questions or queries!

This was a massive team effort with huge help from my supervisor
Stefan Remy, my fantastic colleague @petra_moce, and feedback and encouragement from many friends and colleagues (esp. [email protected]) that have helped carry this through a pandemic, paternity leave, and a lab move.

A hippocampus-accumbens code guides goal-directed appetitive behavior - Nature Communications

The dorsal hippocampus plays an important role for spatial memory, but how its outputs guide behavior is not fully understood. Here, the authors show that nucleus accumbens-specific hippocampal projection neurons carry a highly conjunctive code of spatial and action information that directs spatial reward memory-guided appetitive behaviors.

I guess it's time to finelly do my #introduction !
I'm a PhD student in Michaël Zugaro's lab
I'm studying the interaction between spatial coding in the #hippocampus and reward representation by #dopamine signaling, especially the VTA - Nucleus Accumbens pathway.

The dying bird convinced me that mastodon was the way to go and I'm glad to see the neuroscience community growing!

I'm a bit shy on social media but I'll boost everything related to the brain that I find interesting 🧠

Our focus will be on teaching you how to do surgeries and successfully running your own single-photon head-mounted miniscope, two-photon head-fixed imaging, and freely moving optogenetics experiments, and being able to synchronise and analyse this data with behavioural tracking.

We are truly excited for a great line-up of speakers and instructors this year, including Karel Svoboda, @TrackingActions, Daniel Dombeck, @antihebbiann, Valentina Emiliani, Sabine Krabbe, Yunyun Han and more!

There will also be time for some fun and hanging out (see pics from 2021). Previous students had this to say: "honestly, LINdoscope blew my mind. I learned way more than I had even hoped, and formed amazing relationships [...] I would HIGHLY recommend this course to others"

LINdoscope 2023 organisers are Alessio Attardo, Oliver Barnstedt (@obarnstedt), Sanja Mikulovic, and Matthis Prigge from LIN Magdeburg, as well as Janelle Pakan (@PakanLab, OvGU Magdeburg) and Anne Petzold (@neuroadept, UKK)
