Just a few more days left to nominate your female colleagues! 🧚‍♀️ Help spread some joy and appreciation for the women who do so much for our field, not just in terms of their outstanding research, but also all the labor that they do to support the wonderful WM community that we have!

To adapt to a new prior, tuning curves should "move" toward more frequent stimuli ('prior attraction'). But in adaptation studies they are shown to move away from the more frequent stimuli ('adapter repulsion'). Oh also how do tuning curves move at all?? www.nature.com/articles/s41...

Fast efficient coding and sensory adaptation in gain-adaptive recurrent networks - Nature Communications

How sensory systems rapidly adapt to changing stimulus statistics remains unclear. Here the authors show that gain adaptation in recurrent networks can implement fast efficient coding, unifying prior ...

I am recruiting a postdoctoral researcher and a PhD student, funded by a new ERC grant. The grant focuses on the role of the hippocampus in visual perception, using 7T fMRI (hippocampal subfields, cortical layers) and MEG+iEEG. The intended start dates for both positions are in early 2027. 🧠🟦 1/3

Online Now: Bayesian efficient coding as a theory of perception: progress, controversies, and prospects

Bayesian efficient coding as a theory of perception: progress, controversies, and prospects

Bayesian efficient coding unifies two foundational theories of sensory processing: efficient coding and Bayesian inference. Central to this account is the idea that natural environmental statistics shape both how sensory information is encoded and how it is perceptually interpreted. By unifying these principles, the framework accounts for counterintuitive perceptual biases and establishes lawful relationships between environmental statistics, bias, and discrimination thresholds. In this article, we review behavioural and neural evidence for this theory in perception and cognition, as well as how short- and long-term adaptation to the environment may be expressed within the framework. We further review theoretical developments that extend the original framework, focusing on how response biases can be decomposed into encoding- and decoding-related components. A decade after its introduction, Bayesian efficient coding continues to evolve as a powerful theory, with recent extensions addressing early limitations and opening new directions for investigating perception and cognition.

We have 3 PhD positions at our department (www.jobbnorge.no/nn-no/ledige...). Know a good student interested in working with me on perception / visual memory? I'd be happy to support the proposal! A catch: this person must speak a Scandinavian language as the position implies some teaching duties.

My first foray into explicitly trying to bridge Marr’s levels, with @bealebrains.bsky.social. Inspired by Hahn and Wei’s models (pubmed.ncbi.nlm.nih.gov/38360947/), we wondered how the brain could instantiate sensory inference with efficient /decoding/ properties. 1/

Hi Bluesky community 👋 I’m a data scientist and mathematical modeller with a background in cognitive science, where I used computational models to study how the brain represents information. Now I build data tools and write about making complex ideas clear and useful. Glad to be here!
