🧠🔊 New preprint! How does the brain organise natural sound categories? In our new fMRI study, we show that auditory cortex arranges sounds along continuous functional gradients, where acoustic and semantic structure are integrated into a shared representational space. doi.org/10.1101/2025...

Auditory Cortical Gradients Integrate Bottom-Up and Top-Down Structure During Natural Sound Categorisation

Understanding how the brain organises natural categories is a central challenge in neuroscience. While prior work has shown that categories can be decoded from distributed activity patterns in auditor...

We really need to start naming things in neuro stuff like "the sonic hedgehog pathway"

🚨🐣 Our new paper is out @plosbiology.org! Sonic hedgehog inhibition transforms feathers into ancestral protofeathers-like structures. These units then recover after hatching, highlighting their remarkable developmental robustness! @lanevol.bsky.social 🧪 journals.plos.org/plosbiology/...

This looks great! Excellent work by @davidghaydock.bsky.social et al.

Ever heard of EEG microstates? Usually defined as cluster centres of topography, the dynamics of MS sequences are referred to as "syntaxes". Our new review discusses syntax methods and show how they could be better associated with the underlying EEG signal: 🧵👇 www.sciencedirect.com/science/arti...

In the future we think that #bwas will become more efficient (stable and cheaper) by using tasks and optimising their capacity to seperate trait variance using approaches like this by @leechbrain.bsky.social www.sciencedirect.com/science/arti...

No disrespect but saying that perception of the world is a brain-based best guess is like saying that a wave is the ocean's best guess about what water should do. Brain and world aren't separate things making predictions about each other - they're inseparable aspects of the same dynamic process.

IMO the big breakthroughs won’t just come from advancing temporal and spatial resolution, but from achieving naturalistic recordings during dynamic, embodied interactions. Until we can move away from highly restrictive and overly reductive passive stimulation we won’t fully grasp mechanism.

Challenge: does FMRI have a future (apart from studies of development and ageing)? We want to know HOW the brain works and for that we need millisecond temporal resolution neuropixels, MEG, OPMs. After nearly 30 years of FMRI we know basically WHERE things happen.
