#ICYMI Small electric shocks to ear can help make compassion meditation training more effective at boosting people’s capacity for self-kindness and mindfulness, finds a new study led by UCL PALS researchers.

Neuronal diversity is written in transcriptional codes 🧬. But what is the logic of these codes that define cell types and wiring patterns? To find out we built a #scRNAseq developmental atlas of the Drosophila nerve cord and linked it to the #connectome 🪰🧠 #preprint thread ⬇️1/8

Let's share @etlunsford.bsky.social's work : to survive, animals avoid drifting involuntarily in their environment. While humans rely on visual & vestibular cues, birds & fish need to sense complex flow changes of the external fluid (air/water) around them to select motor actions. How do they do?(1)

Does a cell’s gene expression always reflect its function? Evidence from zebrafish neurons suggests that transcriptionally similar cells can be functionally diverse @ishainer.bsky.social www.nature.com/articles/s41... www.nature.com/articles/d41...

Neurons with identical transcriptomes can have different morphologies and functions! A new study by the Baier Lab published in @nature.com shows that temporal and spatial factors expand the repertoire of genetically similar neurons: www.nature.com/articles/s41... @ishainer.bsky.social

I'm thrilled to announce that our paper describing Marigold, a free machine learning-based webapp for zebrafish behavioral analysis, is officially published! Marigold features a user friendly graphical user interface to enable training of a neural network for analyzing behavioral recordings.

After a long wait, our paper is out! We show that differences in learning between the sexes are modulated by the NPY receptor, which gates sensory perception. Great work by PhD student, soon to be Dr, Sonu Kurien www.nature.com/articles/s41...

Should I stay or should I go?! New study by the Baier Lab shows that in cichlid fish mother and larvae follow their own intrinsic schedules during brood care. This leads to the larvae leaving their home shell exactly 9 days after fertilization. Find out more: www.bi.mpg.de/news/2025-01...
