Visual circuitry for distance estimation in Drosophila
Shomar and Wu et al. investigate how visual circuits estimate distance in Drosophila. A high-throughput screen and calcium imaging identified direction-selective and non-direction-selective visual neu...

Algorithmic dissection of optic flow memory in larval zebrafish
Hysteretic optomotor responses in larval zebrafish have emerged as a simple model of working memory and decision-making. Tanaka and Portugues dissect their algorithm with psychophysics, revealing its ...

I'm back in Japan for the Japanese Neuroscience Society meeting last week in Niigata. It was a great opportunity to reconnect with old friends and meet new colleagues. Sushi was also excellent.

Bit late, but I was at the Lindau Nobel Laureate meeting at the beginning of the month. The topic was a bit out of my expertise, but I learned a lot about chemistry, met a lot of great people, and above all thoroughly enjoyed being at another corner of Freistaat Bayern.

As I transitioned from studying Drosophila to the larval zebrafish, I have been noticing a lot of interesting parallels between their visual systems (esp. tectum vs. lobula), which I feel are not talked about enough. We explored these analogies in depth in our latest review:

On analogies in vertebrate and insect visual systems - Nature Reviews Neuroscience
The visual systems of vertebrates and insects exhibit considerable similarities. In this Review, Tanaka and Portugues discuss these similarities, focusing primarily on recent works in larval zebrafish...

As I am posting these, I am in Awaji island, Japan, for the Cold Spring Harbor Asia conference starting today. The last time I was here I was like 5. The landscape is incredible.

Check out my new preprint:

Here I run a bunch of psychophysics experiments to better understand how the larval zebrafish🐟 remember the past optic flow in the context of stabilization behaviors.

Algorithmic dissection of optic flow memory in larval zebrafish
The visual stabilization behavior in the larval zebrafish reflects the history of optic flow experienced in the recent past. This integrative process has gained traction in recent years as a simplifie...

1/3 How does visual input affect the heading direction (HD) network? In our latest lab preprint, Ryosuke presents "visual landmarks" to larval zebrafish and shows that the HD network tethers to the visual environment. The experiments are again inspired by the beautiful recent work in Drosophila.
