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).
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...

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...
