Great news! Congrats!

We haven't, though that is a very good idea!
h/t to lab grad student Arianna Thoksakis (not on bluesky) for spearheading this one! /fin
This outcome demonstrates that a neural signature of human evidence accumulation - the CPP - can flexibly adapt to evidence present in the external environment, evidence stored in memory, and evidence computed "on the fly" in a newly learned and arbitrary space. 4/N
We found that CPP buildup scaled monotonically with distance from the learned boundary and that individual differences in CPP sensitivity correlated with behavioral estimates of evidence accumulation. Thus, the CPP tracked evidence accumulaton when that evidence was entirely self-constructed. 3/N
To answer this question, we tracked a human EEG potential known to index evidence accumulation - the CPP - while volunteers classified orientation stimuli according to an arbitrary rule. To solve the task, volunteers had to calculate evidence by comparing external stimuli to a learned boundary. 2/N
Another new one from the lab in J Neurosci:

Evidence accumulation is a core principle by which brains convert information into decisions. But what happens when the evidence the brain needs can't be directly read from an external stimulus or memory? 1/N
This and much more in the paper! Our lab is actively exploring ways to build on this work along theoretical and applied lines, so please reach out with questions, criticisms, and ideas!
These data also align with recent work suggesting that "leakage" between visual and motor populations in primate oculomotor areas (LIP, SC) account for stimulus-specific eye movements in common behavioral tasks (Peysakovich et al 2024; Rosen & Freedman 2025).
Caveat: decoding doesn't work well - 3-10% above chance - and the gaze parameters that carry category information are variable over time and idiosyncratic.
(though FWIW, a consistent 3-4% advantage in a local poker room would allow me to self-fund my lab in perpetuity)
They do! We can decode the category of an attended or remembered stimulus from variability in gaze parameters - a behavioral "tell" that could provide insights into both decision making and motor processes.
Thanks to pioneering work by @freekvanede.bsky.social, @bernhardspitzer.bsky.social, @suryagayet.bsky.social, and others, we know that subtle eye movements track information stored in WM. Here we asked whether eye movements track the "meaning" of a stimulus in an arbitrary, learned space.
Proud of this one, led by former lab student Ali Caron (not on bluesky) and online at @jocn.bsky.social.

I dunno, I kinda like it:
"Inspire delta"
"Be the delta you wish to see in the world"
"Hope and delta"
"To improve is to delta, to be perfect is to delta often"
It’s out!
Nice.
Happy Chompsgiving!

Perfect after 3 days at SfN.
Ah, you've never seen the Savannah Bananas play.
Today:
1. Paper rejection
2. Grant rejection
3. Dog made a mess (comforter took the worst but mattress is suspect)
4. New service committee assignment
5. "complete these trainings ASAP" email
6. Dishwasher breaks and soaks kitchen.
Anyway science is hard and I'm getting a beer.

RIP D'Angelo. 1 of 1, and they don't make 'em like this anymore.

We’re looking for a postdoc to join our Max Planck group in Germany some time in 2026. If you have computational and/or neuroimaging expertise, and are interested in questions intersecting perception and cognition, please reach out! I’ll also be happy to chat at the #Bernsteinconference this week.

It is fucked up what they did to the headphone jack
Come work with us! UC Irvine Cognitive Sciences is looking for a new Assistant Professor to join our team: recruit.ap.uci.edu/JPF09896
I'm not on the committee, but happy to talk if you're interested.
I guess calligraphy would be a better term than penmanship but I've had a couple pops.
