Vertebrate eyes first evolved in water, where spectral content rapidly fades with distance. Zebrafish exploit this loss by antagonizing cone signals to suppress the background, pointing to distance es...

How do brains make decisions when faced with multiple, potentially conflicting cues? In our latest preprint, we show how #zebrafish use an additive strategy and process multiple visual features through anatomically distinct parallel pathways tinyurl.com/mvkn8em9 Thread 👇

It’s surreal to think that every neuron and synapse in the fly brain + cord that was dissected almost five years ago (the photo’s still on the lab slack!) is now just a click away on Codex codex.flywire.ai?dataset=banc. This wouldn’t have been possible without the incredible team behind it!
