Official account of the Portugues Lab @Cornell (previously @TUM), studying all things sensorimotor in larval zebrafish.
Have you ever wondered how the brain should represent the sensory world in order to generate behavior? Read our new preprint: work by Shuhong Huang shuhonghuang.bsky.social with our long-standing collaborator James Fitzgerald at Northwestern.

Plastic landmark anchoring in zebrafish compass neurons - Nature
Using two-photon microscopy with a panoramic virtual reality setup, how head direction cells in larval zebrafish integrate visual landmarks and optic flow to track orientation is revealed.

We had a lot of fun working on this project (led by Itzel Ishida, not on bluesky). Some interesting highlights from the paper -
Neuronal calcium spikes enable vector inversion in the Drosophila brain
In the fly central complex, PFNa neurons switch from firing classical sodium spikes when depolarized to firing non-canonical T-type calcium spikes when hyperpolarized. This bidirectional spiking allow...

Adam Kampff’s passion for understanding and explaining the world was unmatched. Living by example and not ever compromising on his dreams, Adam was uncanny in making people realize they can learn and understand anything and everything. Keep his dream alive!

Thrilled to share that our work is now published in Science! ✨

We found a preference for visual objects in the mouse spatial navigation system where they dynamically refine head-direction coding. In short, objects boost our inner compass! 🧭

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)

How does the brain distinguish different types of optic flow?
We combined CaMPARI2 labeling with single-cell RNA-seq (CaMPARI-seq) to dissect visual circuits in zebrafish.
