Sleep-like Slow Waves During Wakefulness Mediate Attention and Vigilance Difficulties in Adult ADHD

We show that intrusions of sleep-like activity during wake help explain attention lapses in ADHD.

I believe the structures are largely identical, not only at the raw level, but also in the details of the operational units. In addition to the circumstances, environment, family, and education, there is something else entirely individual that creates awareness, identity, and a unique personality.

We all share the same intricate blueprint of the head—skull, brain, senses—yet each mind crafts a unique universe. How do identical structures spawn such diverse thoughts, beliefs, and identities? What sparks the symphony of individuality?

How your brain makes a decision before you know it Princeton scientists uncover how brain cells coordinate decisions, offering insight into mental health and cognitive function.

Dr @engeltatiana.bsky.social : “The widespread assumption is that this heterogeneity reflects the complex dynamics involved in cognition,” said Dr. Engel. “But surprisingly, we found that this apparent complexity arises from a very different neural coding principle.”

Findings show distinct brain regions handle individual concepts (frontal/parietal cortex) vs. relations (temporal cortex). LLMs predict brain activity, revealing complex semantic networks.

6/🧵 Together, these findings produce a map of how we build meaning: from concept coding in the occipitotemporal cortex to relational integration in frontoparietal and striatal regions

Come see our full preprint here: www.biorxiv.org/content/10.1...

(Thanks for reading!)

5/🧵 Relational analysis also identified a role of the dorsal striatum. Despite not being typically seen as an area for semantic coding, striatal regions robustly represent relational content, and the strength of this representation predicts participants’ judgments about item pairs

4/🧵 We used LLM embeddings to model neural representations via fMRI and RSA, which revealed dissociations in information processing. Occipitotemporal structures parse concepts but not relations. Conversely, frontoparietal regions (especially the PFC) almost exclusively encode relational information

3/🧵 Next, we tested relational information. LLM activity for texts like “A prison and poker table” robustly predicts human ratings on the likelihood of finding a poker table in a prison. Further analyses show how LLMs parsing such texts also capture precise propositional relational features

2/🧵 To produce concept embeddings, we submit a short text (“A porcupine”) to contemporary LLMs and extract the LLMs’ residual stream. Leveraging data from our normative feature study, we find that LLM embeddings better predict human-reported propositional features than older models (word2vec, BERT)

🚨 New preprint 🚨

Prior work has mapped how the brain encodes concepts: If you see fire and smoke, your brain will represent the fire (hot, bright) and smoke (gray, airy). But how do you encode features of the fire-smoke relation? We analyzed fMRI with embeddings extracted from LLMs to find out 🧵

A screenshot of the first page of a newly published forum article entitled "Advancing GWAS of human communication" authored by Rosa S. Gisladottir in the journal Trends in Genetics. The abstract reads as follows: The last decade has seen an explosion in genome-wide association studies (GWAS) on almost any imaginable phenotype. Unfortunately, humanity’s most distinctive trait – communication, broadly construed – has been underserved. In this forum article I review recent advances and promising avenues that may help us understand the genetics and evolution of human communication.

Highly recommend this superb forum article on genomics of human communication traits, free to read in @cp-trendsgenetics.bsky.social. Beautifully succinct & accessible overview by @rosagisladottir.bsky.social on where the field is now & where it's heading. 🗣️💬🧠🧬🧪

I'll explore these in my next study:
What determines our conscious #awareness? Why are some neural processes #conscious, others subconscious? How is information filtered for #consciousness? What distinguishes what we’re aware of, what we could be aware of, and what we can’t be aware of?

What questions should a comprehensive theory of consciousness consider?

Surveying the field more broadly, I would argue that we do not actually have any “theories of consciousness”.
