Realigning incentives for biomedical researchers and journals through researcher-shared outputs In this preprint the authors propose a shift in what counts in the biomedical sciences: researchers should be recognized for what they choose to share on their own terms and timeline (for example as p...

Scientific publishing needs to change. HHMI President Erin O'Shea and Bodo Stern argue that the incentives are misaligned. Researchers should be evaluated on what they choose to share, not what journals select. Proud that HHMI @hhmi-science.bsky.social is leading the way. Pre-Print: bit.ly/4sDCCsu

Letter asks Congress for nearly $500 million to sustain BRAIN Initiative The boost would help counter the planned sunsetting of one of the program’s long-standing funding streams.

The requested boost would help counter the planned sunsetting of one of the program’s long-standing funding streams, which will result in a $195 million drop in funding for fiscal year 2027.

Repeated Viewing of a Film Clip Changes Event Timescales in The Brain Many everyday experiences share a recurring structure: routines, familiar routes, rewatched films, and replayed songs. How do repeated encounters with such structure alter the brain’s representations ...

How do the brain’s event representations change as we gain familiarity with an experience?

Brain regions’ representations can become coarser or finer as events become familiar. Slow-timescale structure predicts memory.

Excited to share this work w/ Narjes Al-Zahli & @chrisbaldassano.bsky.social!

Multiple sources of β2*-nicotinic acetylcholine receptor binding are differentially affected during tobacco smoking abstinence as revealed by Independent Component Analysis of [18F]Flubatine PET images Neuropsychopharmacology - Multiple sources of β2*-nicotinic acetylcholine receptor binding are differentially affected during tobacco smoking abstinence as revealed by Independent Component...

Using independent component analysis of [18F]Flubatine PET to dissociate β2-containing nicotinic ACh receptor subtypes in the human brain, this study found that subtype-specific nicotinic receptor adaptations may inform smoking cessation therapies

Dr. Jay Bhattacharya on His Mission to Rebuild Public Trust in the NIH and CDC He discusses "DEI" research, campus funding freezes, ACIP, and the path forward for the nation's public health infrastructure

The @whyshoulditrustyou.bsky.social team asked some tough questions of NIH Director Bhattacharya. It's worth a listen: substack.com/home/post/p-...

I wanted to add some additional context on Bhattacharya's responses. Sorry, long thread.

Duration between rewards controls the rate of behavioral and dopaminergic learning - Nature Neuroscience Cue–reward learning rate scales proportionally with the time between rewards. Consequently, learning over a fixed duration is independent of the number of trials. This challenges trial-based dopamine ...

Very excited to post our paper led by @daburke.bsky.social www.nature.com/articles/s41... where we uncover a simple mathematical rule underlying how brains learn that a cue predicts a reward. 1/26

PhD students’ taste for risk mirrors their supervisors’ Learned risk-taking behaviours can persist for years after leaving the lab — and even after taking on a new research topic.

A researchers’ propensity for risky projects is passed down to their doctoral students — and stays with trainees after they leave the laboratory
