Our latest findings: bringing together the core insights so far from our NWO-funded project on "Externally driven internal attention", led by @annavanharmelen.bsky.social: www.biorxiv.org/content/10.6...

Excellent opportunity to join our wonderful vision science / cognitive neuroscience community in Giessen! Application deadline is tomorrow! 🚀

We believe visual neuroscience is undergoing a paradigm shift — and the Beyond Binding exchange in @TrendsCogSci makes it visible. Five papers, excellent critics, and a discussion that sharpened and nuanced our argument. Thread 👇

Here’s to Joey finding our preprint on biorxiv already before I saw the email it had successfully uploaded 🥂Tweeprint (/blueprint) will follow soon. With @amit-rawal.bsky.social and @mjwolff.bsky.social

Excited to share a new paper spearheaded by the wonderful @baror-shira.bsky.social:

We test the link between serial dependence (as an index of continuity) and event boundaries (indexing segmentation). A few key findings in the thread:

My first TEDx talk just came out. It's always fun to talk about your own research area to the general audience, and its even more fun when you are lucky enough to be supported by such a platform. Happy to hear your thoughts :-)

Great work by Roni Tibon (not on BlueSky) - surprising that negligible difference in fMRI correlates of semantic vs episodic retrieval?

In the IPS, but not the VC, spatial locations generalized across hemifield by sequence position. E.g., a location at the left point of the star in the left hemifield shared a common code with the left point of the star in the right hemifield. This indicates abstract coding of sequence in the IPS.

Here’s a thought that might make you tilt your head in curiosity: With every movement of your eyes, head, or body, the visual input to your eyes shifts! Nevertheless, it doesn't feel like the world does suddenly tilts sideways whenever you tilt your head. How can this be? TWEEPRINT ALERT! 🚨🧵 1/n

Over the years, I have written a few Jupyter/Rmd/Matlab notebooks that attempt to teach some statistical concepts, particularly in neuroimaging. You can find them here: www.mrc-cbu.cam.ac.uk/people/rik.h..., though I will say a bit more about each one in a number of posts over next few days.

It won't actually exist for another month or so, but because it now 'exists' on amazon, I'll humbly observe that, after working through this book, your student/trainee would be able to read and understand all but two or three papers in this week's J. Neurosci. Check it out:

Noise in Competing Representations Determines the Direction of Memory Biases Our memories are reconstructions, prone to errors. Historically treated as a mere nuisance, memory errors have recently gained attention when found to be systematically shifted away from or towards no...

@shansmann-roth.bsky.social and I finally finished our paper confirming a unique prediction of the Demixing Model (DM): inter-item biases in #visualworkingmemory depend on the _relative_ noise of targets and non-targets, potentially going in opposing directions. 🧵1/9

Happy to share our new paper in @nathumbehav.nature.com: t.co/Ciq7AKvle5. Using 500k+ behavioral trials, we show that #serialdependence deviates from #Bayesian predictions, pointing to a new narrative about how recent experience shapes perception. @aozkirli.bsky.social @achetverikov.bsky.social

Visual working memory prioritization modulates serial dependence beyond simple attentional effects - BMC Biology Background Serial dependence (SD) is a contextual bias in visual processing, where current perception is influenced by past stimuli.

Our new paper tests Bayesian and Demixing Model's ideas about the role of noise in serial dependence by manipulating prioritization in VWM via cueing and extra maintenance instruction, and finds mixed support for the models. 1/n bmcbiol.biomedcentral.com/articles/10....

Concurrent selection of internal goals and external sensations during visual search Internal and external selection processes can codevelop in time to yield efficient search behavior.

Now out in #ScienceAdvances: @baiweiliu.bsky.social and I ask how internal (goal) and external (sensory) selection are coordinated during visual search. The key insight: internal and external selection are not inherently serial, but may develop in parallel in the human brain: doi.org/10.1126/scia...

Any early-career researchers in #workingmemory wanting to contribute to an #openscience initiative? I'm looking for help building up a data hub resource for the field. Volunteers can expect to devote a few hours, and might pick up insights into handling research data and how to use Github.

📣 Out in TINS (@cp-trendsneuro.bsky.social):

Neural processing is often described as either externally or internally directed. In our new Forum article, we (@freekvanede.bsky.social & Kia Nobre) propose a multilevel framework for conceptualising external and internal continua of brain processes.

Sensory reformatting for a working visual memory A core function of visual working memory (WM) is to sustain mental representations of recent visual inputs, thereby bridging moments of experience. This is thought to occur in part by recruiting early ‘sensory’ cortical regions, via flexible fronto-parietal mechanisms. The nature of visual cortex activity during WM has been elusive, but new evidence suggests that early WM representations can transform from a sensory-like code into a format that is shaped by task context and optimized for behavior. Here, we review evidence for transformations in visual cortical WM coding, the various forms they take, and their functional importance. Visual cortex may be an active workspace during WM, where flexible and ‘good enough’ WM representations serve to interface with perception and action.

Microsaccades strongly modulate but do not directly cause the EEG N2pc marker of spatial attention Researchers often study human attention using microsaccades and the N2pc EEG marker, but it is unclear to what extent microsaccades contribute to N2pc. This study shows that microsaccades modulate N2p...

The human-neuroscience N2pc marker of covert and internal attention co-occurs with spatial biases in microsaccades, 200-300 ms after prompted to shift attention. (How) are these empirical phenomena related? Check it out in the latest work led by @baiweiliu.bsky.social:

The manuscript also includes practical analytical tips for controlling swap errors, as well as a new non-parametric method for estimating biases.
