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...

🚨 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).

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...
