Wow. This Nature paper is incredibly interesting and worrying. The authors show that LLMs may pass subliminal properties to other models. For example, if an LLM likes owls and is used to generate training data for another model, then the other model may also end up liking owls. This happens subliminally, meaning that it can persist even after semantically related mentions are carefully removed from the training data. They also find a similar effect with misaligned behaviour, raising the concern that unsafe tendencies may be passed from model to model in ways that are hard for humans to detect. This seems to happen especially when teacher and student share the same, or a behaviourally matched, base model. This opens a quite disturbing possibility: models may inherit hidden traits from other models, even when those traits are not explicitly visible in the training data. * Paper in the first reply

Some of these questions will hopefully be answered in future work. In the meantime, we believe this work helps integrate the entorhinal cortex into a pathway from perception to action: action representations allow the EC both to tell us where we are, and what we can do 8/10

Thank you to everyone who contributed to this work, especially our co-authors @ThevesStephanie (co-senior author) and Christian Doeller @doellerlab . Dr Alex isn’t very social (media), but would love to hear comments and suggestions via email (see the paper). 9/10

I spoke to Anthropic’s AI agent Claude about AI collecting massive amounts of personal data and how that information is being used to violate our privacy rights. What an AI agent says about the dangers of AI is shocking and should wake us up.

Congrats Chiara! Nice thread here! #unconscious #semantics
Can we process meaning unconsciously? Our new study suggests: not really… unless language has a way to express it! New paper out with Andrea Nadalini @D_Casasanto @CrepaldiDavide @BottiniRob

At #SfN2025 presenting our new work on how the brain searches memory like it navigates space—using hippocampal theta dynamics to forage through conceptual knowledge and theta-gamma phase amplitude coupling to shift between semantic patches. Join me at Poster TT14 on Monday 1-5 pm

At #SfN2025? Check out my poster TT15 on Mon 17th on how lack of visual experience drives episodic remapping during conceptual-space navigation. Session at 1 PM; I’ll be there from 3:30 PM. Contact me if you’d like to meet earlier! #blindness #gridcoding #remapping

Interesting symposium in Rome on memory, from basic research to application, to pay homage to the career of Giuliana Mazzoni. Happy to be part of it!
