New preprint from our lab! Through psychophysical experiments and computational modeling, we propose a two-stage model in which numerosity aftereffects arise from both feature-selective sensory adaptation and feature-invariant numerosity adaptation. www.biorxiv.org/content/10.6...

Numerosity adaptation reflects multiple levels of sensory processing
Psychophysical and neuroimaging studies have repeatedly suggested that perceived numerosity is susceptible to adaptation, involving high-level number representations. However, whether adaptation to lo...

Is spatial navigation innate 🧠? Using #NeuroPixels we show that the #torus 🍩 underlying the #GridCell map exists already on day 10 in rats — before pups open eyes and ears and before they start upright walking. 🧵1:4 👇 www.biorxiv.org/content/10.6...

1/n We have discovered that bees can keep track of time duration! Bees can discriminate long 🟡🟡 vs short🟡 flashes, a bit like the "dash" and "dot" of the Morse code. Check our new paper royalsocietypublishing.org/doi/10.1098/... and videoclip youtu.be/hsGxU65OMQk?... @preparedmindslab.bsky.social

🚨 Job Alert ‼️ 🚨 I’m looking for a postdoctoral researcher with strong experience in neuroimaging (and/or other related techniques) and an interest in exploring the concept of relative coding, as proposed in our latest work (quoted below).

Motor Preparation Tracks Decision Boundary Crossing Rather Than Accumulated Evidence in Temporal Decision-Making
Interval timing, the ability of animals to estimate the passage of time, is thought to involve diverse neural processes rather than a single central “clock” ([Paton and Buonomano, 2018][1]). Each of t...

Our latest work is out in @naturecomms.bsky.social ! We show that numerosity is represented as a “relative code,” which gradually emerges in the frontoparietal cortex. Congratulations to @_tkido (on X) from the @yukoy.bsky.social Lab on his first first-author paper! www.nature.com/articles/s41...
