Is the pain of null data taking up slots in your working memory? Or shifting you over optimum arousal on the Yerkes Dodson curve?

Not for me! I've externalized it to this lovely preprint!

Plus, read on for why it might not be the pain that causes deficits in your working memory... 🧵

When is a "pathogenic" variant in a classic pain gene (NaV1.7) not pathogenic? When its carried by many thousands of people and has no evidence of a pain phenotype or analgesic prescriptions... We need to reconsider how we assign pathogenicity to these variants.

Carriers of SCN9A variants linked to inherited and acquired pain syndromes show no alteration in the prevalence of pain or analgesic usage in the UK Biobank cohort
The voltage-gated sodium channel NaV1.7, encoded by the SCN9A gene, is integral to nociceptor excitability and pain sensation. Multiple gain-of-function SCN9A variants have been reported to cause auto...

Interested in dopamine? Have fMRI data? We’ve identified a temporal BOLD feature that carries rich information about dopamine physiology. This measure, obtainable from resting-state and task fMRI, opens new ways to indirectly probe dopamine’s role in cognition and disease. 1/n tinyurl.com/bddyz67b
Temporal fMRI Dynamics Map Dopamine Physiology
Spatial variations in dopamine function are linked to cognition and substance use disorders but are challenging to characterize with current methods. Because dopamine influences blood vessel dilation,...

Why do we remember so many details of our experiences even when it is unclear if we will actually ever need them?

In a new preprint, @marcelomattar.bsky.social and I asked whether this property is adaptive, because what will be relevant in the future often (usually?!) isn’t apparent.
Episodic memory facilitates flexible decision making via access to detailed events
Our experiences contain countless details that may be important in the future, yet we rarely know which will matter and which won't. This uncertainty poses a difficult challenge for adaptive decision ...

Are you feeling stuck in your ways? Less excited about exploring anything new? You may be aging!
