1/5 Over a decade of comparing deep neural networks to the human brain—but what have we actually learned? Our new @cp-trendscognsci.bsky.social Feature Review synthesizes a decade of brain–DNN comparisons, asking what they reveal about brain function across vision and language.
What makes some stimuli more memorable than others? In a new paper w/ @davogelsang.bsky.social, we show that the magnitude of a stimulus's ANN representation predicts both image and word memorability Stimuli that activate more features, more strongly, leave a stronger memory trace Out now in JML⬇️
A huge effort and a new take on what constitutes the "feedforward pass" across the visual system. Make sure to check out our new preprint:
Excited about our new preprint: “The illusory simplicity of the feedforward pass: evidence for the dynamical nature of stimulus encoding along the primate ventral stream” arxiv.org/abs/2604.12825 Work with Sushrut Thorat, Anna Mitola, Paolo Papale, Peter König & Tim Kietzmann 🧵 thread below

New peer-reviewed paper w/ @mheilbron.bsky.social, @predictivebrain.bsky.social & Jakub Szewczyk! Pre-onset brain encoding has been taken as evidence that brains–like LLMs–predict upcoming words. We show that the same signatures arise in systems that cannot predict. (elifesciences.org) (1/8)
📢Publication Alert: New Paper on Human Pavlovian Fear Conditioning! It has been speculated that psychophysiological responses to an outcome during learning could express prediction errors. ➡️ onlinelibrary.wiley.com/doi/10.1111/... #associativelearning #psychophysiology #PavlovianFearConditioning
<em>Psychophysiology</em> | SPR Journal | Wiley Online Library
Pavlovian reward learning is driven by prediction errors (PE), but it remains unclear whether this is also the case for aversive learning, and to what extent PE are expressed in physiological indices...

JOB ALERT: PhD opening in my lab! @cimecunitrento.bsky.social in Italy, as part of an Italian FIS3 starting grant. The project will use advanced analysis methods of MEG data to investigate how our world's naturalistic hierarchical structure facilitates predictive neural processing.
I recently had the pleasure to visit the great Neurospin institute in Paris where I presented my work on the neural prediction of naturalistic dynamic input: www.youtube.com/watch?v=Ywxt... Some data from the talk is published at: doi.org/10.1038/s414... and doi.org/10.1101/2025...

Check out our new paper out in communications psychology! @commspsychol.nature.com
This study shows that past experiences alter the basic processing of visual input, showing that learning alters attentional processing in a similar way to what was previously shown with endogenous and exogenous attention. @docdocdunk.bsky.social @jthee.bsky.social www.nature.com/articles/s44...
New paper! 🚨 ~1.8K Mooney images from THINGS + ~1K participants to study visual ambiguity resolution. Results suggest the visual system shifts from a top-down guess to bottom-up matching after disambiguation, and a U-shaped link between info gain and identification. www.nature.com/articles/s44...
Temporally-precise sensory encoding of predicted content, entraining motor oscillations to derive time. @akalt.bsky.social's first study out @currentbiology.bsky.social, testing parts of this idea (tinyurl.com/TiCSKaltenma...). Huge thanks @leverhulme.ac.uk ac.uk @erc.europa.eu, great work Aaron!
Fixed and flexible perceptual rhythms
Our sensory inputs are never identical across time and contain temporal structure. Cognitive scientists have recently been fascinated by how these sensory rhythms interact with neural oscillatory rhyt...

Regularization, Action, and Attractors in the Dynamical “Bayesian” Brain
Abstract. The idea that the brain is a probabilistic (Bayesian) inference machine, continuously trying to figure out the hidden causes of its inputs, has become very influential in cognitive (neuro)sc...

@dotproduct.bsky.social's first first author paper is finally out in @sfnjournals.bsky.social! Her findings show that content-specific predictions fluctuate with alpha frequencies, suggesting a more specific role for alpha oscillations than we may have thought. With @jhaarsma.bsky.social. 🧠🟦 🧠🤖
Contents of visual predictions oscillate at alpha frequencies
Predictions of future events have a major impact on how we process sensory signals. However, it remains unclear how the brain keeps predictions online in anticipation of future inputs. Here, we combin...

Out now @cp-trendscognsci.bsky.social, w/ @akalt.bsky.social & @drmattdavis.bsky.social. Are sensory sampling rhythms fixed by intrinsically-determined processes, or do they couple to external structure? Here we highlight the incompatibility between these accounts and propose a resolution [1/6]
New MEG paper by @jhaarsma.bsky.social and @dotproduct.bsky.social! Same design and behavioural results as our 7T layer fMRI study (www.jneurosci.org/content/43/4...), but now shedding light on the temporal dynamics of the sensory signals underlying false percepts. #neuroskyence
Shared and diverging neural dynamics underlying false and veridical perception
We often mistake visual noise for meaningful images, which sometimes appear as convincing as veridical percepts. This suggests considerable overlap between the mechanisms that underlie false and verid...
