"Regressing a signal away does not make it an artifact". Please check out our commentary on the Frömer et al paper (2024, Nature Human Behaviour) in which we highlight important problems with the analysis and interpretation of their perceptual choice data. biorxiv.org/content/10.110…

We have a new pre-print out looking at what post-decision ERPs can tell us about confidence across two experiments, with @RedmondOConnell, @spk3lly, and Wouter Rys, ...

When Bayesian brain theories talk about 'precision', what precisely do they mean? In @CurrentBiology @cdfrith & I explain how precision has shaped thinking about perception, learning, metacognition & social interaction. But some key puzzles remain unsolved cell.com/current-biolog…


Pretty sure this is the most accepted a poster abstract can get

Just over two weeks left to apply for this PhD position in our lab! If you want to use advanced neuroimaging to unravel how the brain computes the contents of perception, please apply.

We have an opening for a funded PhD position in our lab, to start 1 Feb 2022. If you're interested in using MEG and/or 7T fMRI to unravel the neural computations underlying the contents of visual perception - apply! Any Qs, get in touch. ucl.ac.uk/ion/equality-d… RTs appreciated!

Interested in predictive coding? @drclbuckley, @anilkseth and I have put together a comprehensive new review covering both the core theory in an accessible way as well as many recent advances in the field. Check it out at: arxiv.org/abs/2107.12979

Our brains predict the outcomes of our actions, shaping reality into what we expect. That’s why we see what we believe. From the archive: aeon.co/essays/how-our…

So what's new? i always hate that question. But when @NatRevNeurosci asks for my reflections on neuroscience to celebrate its 20th anniversary, I reflect. Here are said reflections from me and loads of wonderful neuroscientists. Interesting read! nature.com/articles/s4158…

Bayesian brain theories propose a fundamental shift in how we think about the mind, with goals and desires replaced by predictions and errors. In @NatureComms @CeliaHeyes, @ClarePress & I argue why we should resist this ‘desert landscape’ view of cognition nature.com/articles/s4146…
