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

Sometimes I learn a new concept online - like "AI-generated participants in Psych experiments" - and I wonder whether the purpose of the whole internet is just is finding ever more bespoke pieces of information that make me specifically as angry as humanly possible.
AI-generated ‘participants’ can lead social science experiments astray, study finds
Data produced by “silicon samples” depends on researchers’ exact choice of models, prompts, and settings
