1/ Early-life stress changes how we handle later threat.
However, most research averages across animals and tracks a few readouts, so individual stories get lost.
We changed that with ML-driven computational ethology to map coping one mouse at a time.
New #bioRxiv preprint 👇
biorxiv.org/content/10.1101/…
A rather 'unique' paper from our lab is online in @CellReports now. Unique in the sense that I don't think anyone else will be rushing to optotag cortical interneurons in the early postnatal brain... because it is nigh on impossible!
doi.org/10.1016/j.celrep.202…
Great credit must go to the team @GhezziFilippo, @IntoNeurons, and the rest of the gang for persevering and demonstrating that (mainly SST) interneurons contribute to the formative activity that sculpts and creates the circuits that underpin our conscious thoughts.
What does the claustrum actually do?
This study explores how this mysterious brain region processes sensory signals and connects across the cortex. While the evidence for its role is still incomplete, the data offer a useful foundation for future work.

Happy to share this new paper from the lab in collaboration with George Augustine, characterizing synaptic connectivity between the claustrum and the anterior cingulate cortex. Congratulations to Roberto, Zach, and all co-authors! @RobertodelaTor

"Presynaptic and postsynaptic determinants of claustro-cortical connectivity"
CLA→ACC projections are highly specific: defined by presynaptic identity, postsynaptic target, and cortical layer.

Our study on the impact of altered serotonin (5-HT) signalling on developing sensory cortex is now live @NatureComms
We use longitudinal in vivo imaging of 5-HT & neural activity to show that this neuromodulator is buffered in early life to promote bottom-up instruction.
Increasing 5-HT through genetic, pharmacological (SSRIs) or adverse stimuli results in an altered trajectory for the development of GABAergic interneurons, impacting early activity and – in the case of SSRIs – that present through to adulthood:

Many thanks to all the team & our collaborators but especially @OcanaSantero for his amazing in vivo imaging & @WarmingHannah for her top patching skills. Significant contributions from @paqio and @yulonglilab. The work was funded by grants from @UKRI_News & @ERC_Research
How do cognitive maps fail? And how can this help us understand/treat psychosis? My lab at Experimental Psychology, Oxford is hiring a Postdoc tinyurl.com/2p935hhz and RA tinyurl.com/3myfpb78 to answer these questions in mouse models.

Check out our poster A67 on cortical somatostatin interneurons of postnatal mice, from molecular to systems level, at #SfN24 tomorrow morning. This work is from the @Interneuron_Dev lab together with @ENtaouka, @antpcolorado, and Lynn Geyer in collaboration with @HjerlingLeffler.
If you are at #sfn2024, come check poster M17 this afternoon to see how we used gated deep neural networks and all-optical experiments during learning to unveil a new role of cortical serotonin. A collaboration between @SaxeLab@stefsmlab@Interneuron_Dev@paqio and Trevor Sharp
Why are some neurons more selective than others? We report now in @Nature how calcium permeable-AMPA receptors in PV neurons make them less selective to sensory features nature.com/articles/s41586-0… Long live the geniuses behind this🧠🔍juhyun.kim@thainmueller @rhuganir
