Ilustration for FOR5807 showing sketches of c. elegans and its neuronal networks and molecular form of serotonin and dopamin

🚀 Big news from our @monikakscholz.bsky.social lab! We’re part of DynOrg, a new @dfg.de-funded Research Unit exploring how #GPCR signaling coordinates organ function & animal behavior — from heartbeat to foraging. 🧠💓
#FOR #neurotransmitters

Led by @simwieg.bsky.social from @uniheidelberg.bsky.social, DynOrg is one of 7 new DFG Research Units, supported for up to 8 years. We're thrilled to be on board! 🔬🇩🇪

A must-read (in my humble opinion :)) if you plan to target the locus coeruleus in the rodent system. Selectivity and specificity strongly vary between strategies and mouse lines. But no need to worry: we provide tools and strategies to overcome those limitations.

Die DFG richtet 7 neue Forschungsgruppen ein Das Fördervolumen für die Neueinrichtungen beträgt insgesamt 33,4 Mio. Euro für die erste Förderperiode inkl. je 22 % Programmpauschale für indirekte Projektausgaben. 3 Forschungsgruppen werden um eine weitere Förderperiode von vier Jahren verlängert.

Förderentscheidungen zu #Forschungsgruppen durch den Hauptausschuss der DFG im Rahmen der Jahresversammlung: 7 Neueinrichtungen, 3 Verlängerungen. Die neuen Forschungsgruppen erhalten insges. rund 33 Mio. € für die erste Förderperiode. Mehr zu den Themen / Institutionen: www.dfg.de/de/service/p...

Lab outing 2025. Beautiful weather, beautiful wine, beautiful people

🎉Congratulations Heidelberg University!👏
📣With three successful Clusters of Excellence applications, Heidelberg can compete again for the status as a University of Excellence‼️
The existing cluster 3DMM2O will receive further funding, plus the new initiatives SynthImmune & GreenRobust.
#Excellence

Every lab should have a Bell of Glory. Here is ours and it sounds great

Functional Connectivity Shapes Spine Stability in the Hippocampus https://www.biorxiv.org/content/10.1101/2025.02.07.637112v1

Schaffer commissural inputs regulate the stability of CA1 spatial representation Neuronal representations of the world are dynamic. A striking example is the rapid remapping of the hippocampal spatial code, which occurs even when the environment and behavior remain unchanged. Here...

Looks great. Will have to read immediately to see if it fills the holes in our recent one ;) www.biorxiv.org/content/10.1...

Cool experimental design by @simwieg.bsky.social's lab with optogenetics + calcium imaging: how place cells in CA1 are affected by stimulation of contralateral CA3. They observe less an induction of place fields but somewhat random shifts of existing place fields: www.biorxiv.org/content/10.1...

A major step forward in elucidating the relationship between synaptic plasticity at individual hippocampal synapses and neuronal encoding of external information in the living brain.

On the way to Berlin to celebrate Peter Hegemann's 70th birthday with a surprise symposium (he's not yet on bsky - no risk of spoiling it).
Looking forward to seeing many friends from all over the world. Peter has been a central figure in building this community.
