World models are a highly speculative topic in AI as well as in cognitive science. I’m excited to share my manuscript on investigating internal world models using imagination networks in humans and LLMs! 🧵1/n

Internal World Models as Imagination Networks in Cognitive Agents
What is the computational objective of imagination? While classical interpretations suggest imagination is useful for maximizing rewards, recent findings challenge this view. In this study, we propose...

One interesting thing about this finding: People with ADHD commonly experience issues with time perception, which Ritalin is able to restore. Notably, the networks observed here are the same ones we see in timing studies (including insula!)
This is your brain on Ritalin. Got your attention? Stimulant medications like Ritalin (methylphenidate) do, but not in the way you might think. They don't act directly on the brain’s attention systems! Find out what's really happening in @cellpress.bsky.social. doi.org/10.1016/j.ce...

If we leave aside the more extreme discussions about "everything everywhere" and modularity this is a very cool paper.
So much can be done with data from 260 regions and 60K neurons.

No, this isn’t from some brand-new viral study that dropped last week. It’s one of those widely accepted, repeatedly confirmed, deeply inconvenient facts science keeps bringing up no matter how hard we ignore it.

The whole "Grok admits" "Grok apologizes" thing reminds me of the famous IBM presentation quote that evidently everyone has forgotten. And I do think representing your brand on social media counts as a "management decision".

In today's supplementary reading, I discuss how the late John Searle's Chinese Room is a masterclass in rhetorical sleight of hand - and a lost cause when it comes to generative, productive philosophical thought.

Finally time to share all the things I love about this field all of 2026.

Love: papers that have present an fMRI finding first that inspires a behavioral study to confirm a mechanism.

For example: pubmed.ncbi.nlm.nih.gov/25319696/
Temporal memory is shaped by encoding stability and intervening item reactivation - PubMed
Making sense of previous experience requires remembering the order in which events unfolded in time. Prior work has implicated the hippocampus and medial temporal lobe cortex in memory for temporal information associated with individual episodes. However, the processes involved in encoding and retri …

People keeps saying Apple is "falling behind in AI."

But I think it's because they're the only big tech company that isn't ok with rushing out a low-quality product that constantly spits out misinformation.

Reporting says the holdup is that Apple's not satisfied with the high error rate. Good.
