How dynamics arise from the structure is my biggest interest. In this study, we started with a small step and asked how structure constrains dynamics. Spoiler: would that it were so simple… (1/6)

cool people, follow them!

Delayed, Reduced and Redundant: Information Processing of Prediction Errors during Human Sleep During sleep, the human brain transitions to a ‘sentinel processing mode’, enabling the continued processing of environmental stimuli despite the absence of consciousness. We employed advanced informa...

its amazing how chatgpt knows everything about subjects I know nothing about, but is wrong like 40% of the time in things im an expert on. not going to think about this any further

The Human Insula Reimagined: Single Neurons Respond to Simple Sounds during Passive Listening The insula is critical for integrating sensory information from the body with that arising from the environment. Although previous studies suggested that posterior insula is sensitive to sounds, these...

We think cortex might function like a JEPA. It looks like prediction errors in layer 2/3 are not computed against input (as is the idea in predictive processing), but against a representation in latent space (i.e. like in a JEPA arxiv.org/abs/2301.08243 or RPL doi.org/10.1101/2025...).

Repeated Viewing of a Narrative Movie Changes Event Timescales in The Brain Many experiences occur repeatedly throughout our lives: we might watch the same movie more than once and listen to the same song on repeat. How does the brain modify its representations of events when...

How do the brain’s event representations change as we gain familiarity with an experience?

Brain regions’ representations can become coarser or finer as event familiarity increases. Fine-tuning predicts memory recall.

Thanks Georgie! ☺️

Thank youu, see you Monday! 😊

Thanks Dan - you'll be pleased to know, they were fans of the FOOOF!

Officially Dr Flockton 🎉 Thanks to my brilliant supervisors for their support & great humour throughout my PhD @cejpreston.bsky.social @cademccall.bsky.social @bakerdh.bsky.social & to my lovely examiners for the exciting discussions in yesterday's viva! @mggaskell.bsky.social & Helge Gillmeister

Sensory sharpening and semantic prediction errors unify competing models of predictive processing in human speech comprehension Speech comprehension relies on predictive mechanisms, but models disagree on whether the brain prioritizes expected or unexpected information. This study shows that sharpening of sensory representatio...

Same sound, different perception: Do expectations change what you hear?👂🧠

We paired faces w topics and played the same ambiguous speech w different faces. The brain sharpened sensory signals toward predictions and showed gated prediction errors at higher levels.

Our group has been looking at beta bursts for the last 5 years, but we do it a little differently than most - we group into types them based on their waveforms. In this open access article we lay out why and what we think this might mean
