This person is an AI. But he is still doing a PhD program of cognitive neuroscience. Really weird!!

Wanna know about sensory & memory representations in visual cortex? After integrating the wisdom from several reviewers (and clever comments from 2 more reviewers at #elife still to go), this paper is now officially out: elifesciences.org/reviewed-prepr… (tweeprint below)
Are memories noisier versions of what we perceive? Fundamentally different? Seriously, think about it… Early visual cortex processes what we see around us, but also has information about images briefly held in mind. The two must be different… but how? TWEEPRINT ALERT! 🚨 🧵1/n

Interested in how the internal and external processes work together to support efficient behaviour?! Check our latest findings where we tracks the internal and external selections simultaneously in a visual search task that relies on both processes doi.org/10.1101/2025.0…
📢 Check out our (Larissa Behnke, @freekvanede, Kia Nobre, Sage Boettcher) latest preprint on the neural dynamics of returning to an internal focus in working memory after engaging with an interrupting external-attention task. 🧵 below (1|5) biorxiv.org/content/10.110…
Temporal structure of experience etched on firing of human hippocampal-entorhinal neurons to serve memory & prediction. See our study @Nature at @UCLANsgy, great work by lead author @PTacikowski with @GuldamlaKalendr & @DavideCili support @NIH_NINDS. nature.com/articles/s4158…
Reviewers take note: 57% of people rejected their own argument when they thought it was someone else's. So take it easy with the criticism.
📢 Check out our (Sage Boettcher, @Chetan_Gohil, @freekvanede, @KiaNobre) latest publication in @PNASNews on the neural dynamics associated with shifting attention within vs. between external and internal attention. (🧵 below) (1|6) pnas.org/doi/10.1073/pn…
Happy to see this paper finally out now in PBR! @Psychonomic_Soc In it we ask whether statistical learning can occur for unattended items: it is already well known that learning can alter attention, but does attention also alter learning? rdcu.be/dY7L3
Putting the 'spotlight' on high-level visual cognition deep down in the brain @TrendsCognSci: authors.elsevier.com/a/1k1P04sIRvTB… A pleasure to highlight this exciting study by @b_peysakhovich et al., that can be found here: doi.org/10.1038/s41593…
🚨Two new preprints from the lab! (part 1) Preprint 1: doi.org/10.1101/2024.1… In this work led by @wangsisi2017, we uncover an underexplored component of visual search by studying how people “look into their memory” to verify (confirm/dismiss) potential visual targets.
🚨Two new preprints from the lab! (part 2) Preprint 2: doi.org/10.1101/2024.1… In this work led by @BaiweiLiu, we studied the relation between microsaccades and the N2pc EEG marker of spatial attention, showing how microsaccades strongly modulate but do not cause the N2pc.
#GazeReinstatement & #NeuralReactivation may be linked through a common process that reinstates past experiences during #MemoryRetrieval! doi.org/10.1101/2024.1… Check out our #Preprint that integrates #EyeTracking into the Sherlock #fMRI Dataset (Postdoc work w/@Chris_I_Baker)!

Our latest findings that help appreciate why microsaccades and attention shifts are often correlated but not obligatorily linked: attention shifts do not cause new microsaccades but exclusively bias the direction of microsaccades that happen to be made when shifting attention.
Microsaccades are modulated by covert shifts of attention. A new Article by @BaiweiLiu, Zampeta-Sofia Alexopoulou & @freekvanede shows how shifts in attention bias microsaccade direction without causing new microsaccades. nature.com/articles/s4427…
Preprint alert👇: @wangsisi2017 and I studied how attentional focusing in working memory benefits long-term memory. Take-home: we show that faster attentional allocation during working memory instils stronger long-term memories, as revealed through gaze: biorxiv.org/content/10.110…
How does previous decision impacts current decision? We find reactivation of past decision repels early sensory processing but attracts late decision-making in PFC, i.e., two-stage past-present interactions. biorxiv.org/content/10.110… Big congrats @Hui_Hui_Zhang @Mingho72227712
📢 So happy to see our (@SageBoettcher, @freekvanede, @KiaNobre) paper out in @CognitionJourn! Across two experiments, we investigated the dynamic interplay of perception and working memory (🧵below). (1|7) sciencedirect.com/science/articl…
Over the past years, we have repeatedly shown how microsaccades are a powerful index for selection in visual working memory. We now show that microsaccades also track multi-item rehearsal through memorised locations: eneuro.org/content/11/1/E…
My most recent research article just dropped! Attentional templates are activated in a preparatory fashion for the purpose of guidance in visual search, but how are attentional templates activated when no search is required? Find out below: doi.org/10.5334/joc.341
Excited to share my primer on simulation-based power analysis using R, Python, and Julia! Based on @LisaDeBruine's approach applied todata collected by @kcs_adam, I hope it's a helpful tool for those starting with simulations. Check it out: cjungerius.github.io/powersim/ #DataScience
