Stress is complicated, right?

@USkupio @ampolter & I had a hard think about the way acute & chronic stress impacts the different neural populations in the VTA & I’m really pleased with what we came up with.

Just published in TINS. Check it out!

Grateful to share the sequel to the first paper from my PhD, just out in Nature Communications! A big team effort where we uncover how distinct VTA ensembles encode rewarding vs. stressful experiences.

Huge thanks to everyone involved!

[Frank Meye @fjmeye]

Excited that this is out! Two distinct neuronal ensembles in VTA, comprising comparable cell types, promote stress vs reward behaviors. Plus, these small sets are indispensable for approach/avoidance. Thanks to indispensable @IKoutlas and other authors!

@FlyBottleEscape Looks good! I would be also curious to see how the Cre-ERT2 profile compares to the Fos protein profile.

New research from our group on differences between VTA glutamate neuron subtypes in their signaling of rewarding and aversive experiences

[Frank Meye @fjmeye]

Excited to share a preprint for a project driven by the talented @IKoutlas! Two distinct ventral tegmental area neuronal ensembles, one for opioid reward one for social stress, are indispensable for stimulus-driven approach/avoidance behavior in mice.👇

We're excited to share a new preprint on how, in mice, stress-driven increased fat intake involves altered control by the prefrontal cortex over the lateral hypothalamus. 👇

[Onur Basak @OnurBasak5]

We are recruiting a PhD student embedded in @fjmeye's and my lab to search for cell types critical for the function of Brains reward system and relevant to psychiatric disorders.
If you are passionate about #science, ePhys and molecular work, apply!

Excited to share our findings probing how engram ensembles are formed endogenously! tldr? Both neuronal excitability in min-h before an event & pre-existing functional connectivity help determine which neurons are allocated to an engram ensemble. https://t.co/eL9yA8rySm 1/6

How does the brain enable the learning we need to make adaptive decisions?
Is dopamine involved?

Dr. Ana Sias & team discovered answers. Read on to find out. 🧵👇🏻

Everyone going apoplectic about someone publishing Midjourney hallucinations in a @frontiersin paper, but they're totally fine with people publishing T-SNE hallucinations in @nature.

A tale of two neurotransmitters (glutamate and dopamine). We show how VTA glutamate projections to NAc paradoxically promote reward and aversion. What we found may surprise you!

Excited to share my first preprint with @TomRBeckers and @luyten_laura! 🤩 We investigated if the opportunity to avoid during fear acquisition training had an effect on extinction learning. The three experiments were preregistered & all the data is on OSF
