The real problem isn’t p-values, it’s the epistemology behind them.

Science shouldn’t depend on arbitrary thresholds that change with context.

Knowledge should accumulate, not collapse into yes/no verdicts.

Turning continuous evidence into discrete “significance” decisions is information loss

🧠⏱️ New preprint!
We found that temporal prediction errors are more strongly encoded when an overt response is required, and this encoding occurs in motor rather than sensory space.

💡In sum, our results highlight the neural mechanisms underlying the regulation of semantic exploration during naturalistic narrative production and contribute to a deeper understanding of the neural mechanisms
underlying the role of semantic control in generative storytelling.

#creativityscience

⏳ Remarkably, we also found greater temporal irreversibility during creative ideation between visual and high-level areas, suggesting the enhanced hierarchical structure of causal interactions as a neural signature of creative storytelling.

🧠 Moreover, creative narratives showed unique (between and within) functional interactions across the default mode, salience, and control networks.

🧠 Next, we also applied Connectome Harmonic Decomposition (CHD) to neural dynamics into connectome harmonic modes and found specific spatial frequency patterns underlying the modulation of semantic control during story generation.

🧠 Using decoding analysis, we showed that creative stories were neurally distinct, differentiated from ordinary stories in frontal regions, and from random ones in fronto-temporo-parietal areas.
Crucially, the same brain regions encoded the semantic features that behaviorally defined creativity.

🧠 At the neural level, linguistic and visual areas exhibited neural synchrony across participants regardless of the semantic control level, with parietal and frontal regions being more synchronized during random ideation.

🗣️To quantify creativity and task adherence, we used word2vec to compute semantic distance (novelty) and BERT to estimate surprise (appropriateness). Creative stories fell between ordinary and random ones on both dimensions.

🧠 We isolated the ideation phase from the reporting phase, letting us track brain dynamics during silent story generation. No motion, no speech artifacts.

🎯 We recorded fMRI activity while participants generated 3 types of stories:
✔️ Ordinary (appropriate)
✔️ Random (novel)
✔️ Creative (balanced in novelty & appropriateness)

📖 Storytelling is central to human experience, but how do we regulate semantic exploration during narrative generation?
We used fMRI and deep language models to find out.

🧠 What happens in the brain when we turn ideas into stories, and what makes a story truly creative?

Our latest study explores the neural mechanisms supporting semantic control during narrative ideation.

My latest installment of brain state modeling in creativity is out @ Psychophysiology! We found generating novel metaphors is associated with widespread alpha-band synchronization early on in ideation and, paradoxically, alpha-desynch right before response. onlinelibrary.wiley.com/doi/full/10....

🚨 New Preprint!!

LLMs trained on next-word prediction (NWP) show high alignment with brain recordings. But what drives this alignment—linguistic structure or world knowledge? And how does this alignment evolve during training? Our new paper explores these questions. 👇🧵

Language-like efficiency in whale communication Whale vocalizations follow efficiency rules seen in human language, revealing striking similarities in communication systems.

Do whales optimize their vocalizations for efficiency, just like human language? 🐋🎶 My latest study in

Cognitive psych is often traced back to the 1950s.
Psychology is often traced to Wundt's lab in 1879.
Textbooks speak of "proto-psychologists" like Fechner & Helmholtz in the 1800s... Westerners all.

Have you heard about Ibn al-Haytham, whose work predated them by 100s of years?

My prediction is that in 30-50 years, not a single neuroscientist will study the brain in terms of "regions". These will be the last localizationist-driven decades 🔮
