🔥Our opinion piece with @DuncanAstle on “why we might be better off accepting and embracing the fact that the brain’s connectivity profile is in no way optimal” is now out on @TrendsCognSci. There, we discuss implications for Neuro-AI and psychopathology.

In 1934, we added a gender-neutral pronoun for a single third person.

‘Thon’ was short for “that one.”

It didn’t catch on.

It reminded me of this very annoying concept “causation by absence.” A house burns down, partially also because of all the things that didn’t happen like the fire brigade didn’t make it on time or someone didn’t check the stove.

Neuroscientists Giulio Tononi, Christof Koch, et al. make a strong case for real free will (not an illusion) if Integrated Information Theory (IIT) is the correct explanation of consciousness:
"If IIT is right, we do have free will in a genuine sense: we have alternatives, reasons, and values, we make decisions, and we—not our neurons or atoms—are the cause of our willed actions and bear responsibility for them."

My paper on motor cortex during free flight in bats is online. The dynamics look quite different from the usual picture. Maybe because flight is a hard control problem: hand-like wings, many degrees of freedom, millisecond precision.

Limitations of pupil diameter as a proxy for modes of locus coeruleus activity: https://t.co/t9GIie6aE1

"baseline-evoked relationships of the pupil are not predictive of those in the LC, and vice versa."

New preprint with Andrea Gambarotto. Neuroscience often treats control as a hierarchy: the structures behind a behavior hold a stable rank. We argue this mistakes a configuration for an architecture. 🧵

I had a feeling recently that seems to be corroborated by chats with colleagues, so I decided to share it here.

A lot of systems neuroscientists driven by algorithmic-level questions are going through what looks and feels like a research depression. 🧵

Does biological wiring make a better reservoir?

Our WIVACE 2026 paper benchmarks different C. Elegans connectomes. Randomized baselines often perform better; results depend on the task and configuration.

Our new preprint led by @watanaberkyoto @moriguchiy is out! Does children’s “red” correspond to adults’ “red”?
https://t.co/oGfzJePOxw

Our findings suggest largely yes at ages 5–6, but not always at ages 2–3, at least for some colors. We tested which color corresponds to which by finding the best mapping between children’s and adults’ color similarity structures, without using color labels.

Even at ages 2–3, these structures are globally similar to adults’, but subtle local differences—especially around light blue—can disrupt the matching.

Check out the paper for more details!
