Very happy to share our new review on visual computation in the cephalopod brain, with @vangeliqueallen.bsky.social, out now! We discuss exciting recent advances in understanding how the radically different brain of cephalopods processes the visual scene. 🐙🔬👀 www.sciencedirect.com/science/arti...

Sexier in the city? Urban male great bowerbirds decorate bowers with human-made objects, creating brighter and more varied displays than rural males. Males strongly prefer human-made objects over natural ones, possibly boosting their appeal to females! shorturl.at/lcNY2 @royalsocietypublishing.org
Out today in @royalsocietypublishing.org - we show that crab spiders (the ones you usually see ambushing pollinators on flowers 🕷️🌸) get worse at hunting if their eyes are covered!🫣 Sounds obvious? It's actually quite surprising, here's why... 👀 (1/8) royalsocietypublishing.org/rsos/article...

New paper out in @cp-neuron.bsky.social 🎉 What determines contextual modulation in V1? Why does the visual surround sometimes facilitate and sometimes suppress a neuron's response to its preferred stimulus?
Surprise! The Jeff Bezos-owned Washington Post is against my 5% billionaire wealth tax. I wonder why? If enacted, Bezos would owe $12 billion in taxes, and an average family of 4 would receive a $12,000 direct payment. Poor Jeff would be left with just $224 billion to survive.
New paper out on the decision strategies of bumblebees. When using visual cues to make flower choices, they switch strategy with sensory context, learning as much as necessary, but as little as possible. Based on their training time, we propose a mechanism for this switch. tinyurl.com/2r9d4jrs 🌸🐝🧠
Bees flexibly adjust decision strategies to information content in a foraging task
Bumblebees flexibly adjust their learning strategies to the sensory challenge, balancing costs and benefits of multicue learning.

Universität Konstanz@uni-konstanz.de · 5mo agoDuring their search for food, most insects head specifically for the flowers that promise the highest reward. Researchers from the #UniKonstanz and the @uni-wuerzburg.de have now studied how bumblebees process information about their food sources. Full story: t1p.de/mndcd

Pace of ecology drives the tempo of visual perception across the animal kingdom - Nature Ecology & Evolution
Using phylogenetic comparative methods across 237 species from disparate phyla, the authors show that species with fast-paced ecologies have higher temporal resolution of perception.

Another stick in the wall: we removed part of male great bowerbird bower walls to test effect on courtship displays. Males didn’t just focus on rebuilding the wall, they stepped up effort across all aspects of their display, showing they flexibly invest in multiple signals tinyurl.com/4ujmkw95

New bowerbird paper out, we asked whether male great bowerbirds care about the light environment around the bower where they display to females. Short answer: not really. What they do care about is having a display arena with strong visual contrast on the ground. 🐦 tinyurl.com/2v7rycdz

Multiple anthropogenic stressors can negatively impact species but can a single stressor also have multiple, concurrent impacts? Here we show that light pollution creates several simultaneous impacts to the nocturnal movement ecology of a moth and a spider: tinyurl.com/5eku5bff (1/5)
Creative and important study for understanding visual processing.
Keisuke Yonehara@keisukeyonehara.bsky.social · 8mo agoExcited to share our new work on visual information processing in the retinocollicular pathway. We discovered that while luminance responses can predict motion responses in retinal ganglion cells, this prediction does not hold in the superior colliculus cells. www.cell.com/current-biol...
