🚨🚨!!! Happy to share this work combining theoretical insights from neuroscience, computer science, and economics, published in @NatureHumBehav: "Sensory perception relies on fitness-maximizing codes". nature.com/articles/s4156… 1/n, Brief🧵 👇

@freekvanede @TrendsCognSci @b_peysakhovich Cool! Take a look at our review paper @TrendsCognSci doi.org/10.1016/j.tics… where we emphasize the role of early sensory systems in guiding "higher order processes"

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…

@DrBreaky @RobbRutledge Nice piece! You may find this recent view complementary cell.com/trends/cogniti…

The brain is metabolically hungry but most accounts of cognition do not consider the energy cost of neural activity Here we review the metabolic budget of neural homeostasis + cognition; associated evolutionary constraints; plus disturbances in disease osf.io/preprints/osf/…

@DanBang_ @NeuroCellPress Thanks a lot Dan for bringing this up! It was completely out of our radar😳 .... This is indeed a beautiful demonstration of the contextual influence of the LC-NA system!!!

@RafaPolania @NeuroCellPress Insightful perspective! I hope you don't mind me plugging our recent paper :) It speaks to your point that the relationship between pupil dilation and activity in the LC-NA system is highly context-dependent sciencedirect.com/science/articl…

Check our new Perspective “Neurobehavioral meaning of pupil size” out @NeuroCellPress l1nq.com/6cM2M Fully Open Access! An accessible discussion in addressing the question “What exactly does pupil size tell us about the brain?” is trickier to answer than it looks!! 👁️👁️

Do not miss out on this opportunity!! Incredible lab, facilities, colleagues, and in particular, mentor!! 👇

@weijima01 @NeuroCellPress Oh, thank you Weiji for pointing this out! 👍 Here is the correct link: cell.com/neuron/fulltex…

@RafaPolania @NeuroCellPress Going to read this! Btw the short link seems broken.

Our perspective on the 'Neurobehavioral meaning of pupil size' is out now in Neuron! Come chat about it at my poster at #FENS2024 PS06-28PM-299 on Friday cell.com/neuron/fulltex…

This work nicely complements a Forum article just published @TrendsNeuro by @c_strauch on the origins of pupillometry research! x.com/c_strauch/stat…

This was a fun exercise and collaboration with @DeBurdakov and @umochitju

We have two open postdoc positions in the lab! Check out the links below for details. Postdoc in neuroscience of reward learning: jobs.uzh.ch/offene-stellen… Postdoc in physiology of learning and decision making: jobs.uzh.ch/offene-stellen… Please retweet!

🧠🧑‍💻New preprint from the lab🐭🧲: "Functional-based parcellation of the mouse prefrontal cortex for network perturbation analysis". We combined fMRI, chemogenetics and machine learning techniques to pinpoint distinct functional networks within mice PFC. biorxiv.org/content/10.110…

For this and many other control experiments, analyses and details, take a look at our work nature.com/articles/s4156…

In additional experiments, we show that this modulation depends on the phase of low excitability fluctuations of the prefrontal cortex

🚨New pub!🚨 Is it possible to modulate sensory information processing in a non-invasive manner by modulating ongoing oscillatory activity in the prefrontal cortex in humans? Yes, we can! Take a look at our Open Access pub @NatureHumBehav 👇👇 nature.com/articles/s4156…
