Now online! Zebrafish use spectral information to suppress the visual background

Out now in @currentbiology.bsky.social led by Kaarthik A Balakrishnan: We identify medullary circuits that represent the valence of thermal stimuli and control both long-term strategies of cold-avoidance and short term hot avoidance behaviors to enable thermoregulation. www.cell.com/current-biol...

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity! We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have: (1) more corticospinal neurons (CSNs) (2) better hand dexterity (3) more dexterous climbing, which is linked to CSN number🧵

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)

Excited to share our new paper in Nature! 'Transcriptomic neuron types vary topographically in function and morphology' explores how neurons in the zebrafish optic tectum exhibit diverse functions and shapes despite similar transcriptional profiles. 🔗 rdcu.be/d9GVM

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...
