RIP redundancy reduction?
Beautiful work by Liu & colleagues showing that neural redundancy increases with learning, as predicted by a Bayesian model:

Oh wow, congrats Brady!
Excited to share that our MEG project is now out in Current Biology! We show how visual content codes relate to motor oscillations in telling time.
Huge thanks to Quirin Gehmacher, Peter Kok, Matt Davis and Clare Press (bsky links below).🧵

Sensing Time
Padova, Italy
6-10 July 2026
Ever wondered how humans experience the passage of time? Join the Summer School Sensing Time: How We Process Time Across Real and Extended Realities and immerse yourself in one of the mind’s most intriguing mysteries.
Registration deadline: 15 March 2026
Reminder, happening in 10 minutes!
Even more intriguing, there was work done back in the 80s to survey time across a huge variety of species, finding quite a variety (i.e. pigeons are very good at timing, but turtledoves - same family - are terrible at it). (nyaspubs.onlinelibrary.wiley.com/doi/abs/10.1...)
Fascinating! There's a rich history here of people wondering about timescales across species, going back to the work of van Baer in 1862 (ane.pl/index.php/an...). How do you think this connects?
You had me at Monster Manual
New virtual journal club coming up @timingresforum.bsky.social! Excited to have Ruth Ogden talking about how time matters in our everyday lives. 2/25, 10am EST. Sign-up link below:

🚨Job alert! I'm recruiting a postdoc! If you want to study the time course of task-driven visual perception, please reach out! #neuroskyence #VisionScience #CogSci barnard.wd1.myworkdayjobs.com/en-US/Facult...
Interested in how different aspects of object information, including visual, semantics, and memorability, are encoded and represented in the brain? Check out our latest study in iEEG & fMRI~
Cool findings! It may also be that how subjectively long people felt they were looking at the image predicts perceived beauty
Preprint out, from my work with @mamassian.bsky.social and Anne! We show that time perception is shaped not only by context but also by structural constraints, by extending classical Bayesian models by explicitly quantifying a structural prior impacting duration discrimination.

Whoa! This is awesome! Thanks for making and sharing
Grad school me spent way too many hrs fighting matlab to generate dot arrays and extract parameters from pre-existing stimuli. So I built the thing I wish existed: an open-source, browser-based toolbox for generating AND analyzing dot arrays. No MATLAB, no installation, no inherited spaghetti code
Just curious: which part of your experience taking stims adds to the incredulity? (I get and share the neuroscience part, but am genuinely curious about the former)
The irony/paradox is that dopamine also dilates (lengthens) perceived duration. And so motivation/guidance can't be just about minimizing experienced duration - the lengthening can be a cue for reinforcement
www.nature.com/articles/s41...
Why, yes! Time is completely subjective and contextual. Plenty of work linking motivation/outcomes/timing in the guidance of action (and perception! see: doi.org/10.1177/0956...). But also see: doi.org/10.1016/j.ne... and doi.org/10.1016/j.be... for some fantastic links).
Oh boy, happy to assist!
In terms of brain regions, there's been a good number of meta-analyses now on this (here's one direct.mit.edu/jocn/article...
But if you're curious about time and pathology, this 2012 review by Melissa Allman is an all-time classic:

One interesting thing about this finding: People with ADHD commonly experience issues with time perception, which Ritalin is able to restore. Notably, the networks observed here are the same ones we see in timing studies (including insula!)
Our holiday celebrations are especially happy this year, with a new paper out: "Global and Local Deviance Effects in the Processing of Temporal Patterns", about how we detect and keep track of temporal regularities.
Congrats to @duniagiomo.bsky.social and the whole team!🎉

Very exciting stuff. Although, maybe what we call the “attention” network isn’t necessarily doing only that (and the other networks may similarly contribute to attention in other ways).
But, as a parent of an ADHD kid, these results match a lot of what I see! Great work!
Very cool and looking forward to reading closely! You might be interested in our recent results on image memorability vs model entropy. We also see a detrimental effect at high levels. Would be curious to explore a connection.

Happening soon!
I'm sure we never engaged in that behavior in grad school 😉
Great work and congrats! Honest question: are there laterality effects here? I see IT was recorded bilaterally but HC on the left
Hey, listen! Very excited for the next @timingresforum.bsky.social virtual Journal Club!
Farzaneh Najafi will be giving a talk on her recent work on intrinsic timing and ramping dynamics in visual and parietal cortices. Registration link below!

Cool! Will be very interested to hear your thoughts
