If the observed alterations in genomic signal affect their long term resilience is up for debate … and e.g., linked to the past years shift in their distribution and where they spawn … this urge for higher awareness on how we exploit out stocks ‼️ @unioslo-cees.bsky.social @biovitenskap.bsky.social

- Hvis dette kan skje ett sted, kan det skje igjen. Dette er en tragedie for mitt land, men det er enda verre om vi ikke kan lære av det, sier Khoung van Dinh fra @biovitenskap.bsky.social www.titan.uio.no/energi-og-mi...

Are cue-specific reactivations in the cortex necessary for consolidation and learning? To address this we targeted neural activity in POR after daily training in a Go/NoGo task

Using this setup we show that post-training reduction of PV+ activity completely prevented learning. On off-days with saline injections the mice improved, but reverted to chance levels after a single hM4Di activation

We used RiboL1 jGCaMP8 to image large populations of neurons during training and rest. Controls developed a bias to the rewarded cue while the responses in hM4Di mice remained exactly like the naive state

Next we looked at the activity in post-training rest. Reactivations in controls were biased to the rewarded cue and persisted for hours, but with hM4Di activation the reactivations barely happened, despite higher overall activity in the population

The reactivation content was way more specific to the experience in controls. Overall, our data shows that both reactivations and consolidation relies on intact PV+ activity locally in the cortex.
