Addressing degeneracy in rodent studies of cognition In order to relate neural dynamics to cognitive computations, it is critical to determine whether subjects are employing behavioral strategies that ac…

Acetylcholine demixes heterogeneous dopamine signals for learning and moving Nature Neuroscience - Jang et al. measured dopamine and acetylcholine release in the striatum of rats performing a decision-making task and found that the relative timing of cholinergic and...

Thrilled to share our new paper, which shows that the relative timing of cholinergic and dopamine release dynamically gates whether dopamine acts as an RPE for in vivo plasticity and reinforcement learning. www.nature.com/articles/s41...

A study from Rockefeller's @danielkronauer.bsky.social in @currentbiology.bsky.social finds that ants continually update their sense of nestmate identity and tolerance for outsiders, a discovery that opens the door to studying the neural circuits behind social recognition.

Thank you for the great summary, @thetransmitter.bsky.social, and the shout-outs from scientists we admire. There is so much we don’t know about how sex hormones modulate behavior and we’ll keep exploring!

Sex hormone boosts female rats’ sensitivity to unexpected rewards During the high-estradiol stages of their estrus cycle, female rats learn faster than they do during other stages—and than male rats overall—thanks to a boost in their dopaminergic response to reward…

“It’s giving mechanistic insight into how estrogen modulates reinforcement learning—all the way down to the molecular mechanism,” says Ilana Witten.

Estrogen modulates reward prediction errors and reinforcement learning - Nature Neuroscience Dopamine encoding of reward prediction errors naturally fluctuates over females’ reproductive cycles with estrogenic signaling due to reduced expression of dopamine reuptake proteins.

Thrilled to share our new paper, out now in @natneuro.nature.com, uncovering how estradiol, the most potent estrogen, modulates reinforcement learning and reward prediction errors across biological levels. www.nature.com/articles/s41...

'Foraging as an ethological framework for neuroscience'

Had a lot of fun co-writing to this review! Discussing #foraging through the lens of neuroscience.

Really excited to share a review I contributed to, out now in @cp-trendsneuro.bsky.social. We explore how foraging can offer a framework for studying brain and behaviour in natural contexts. It’s been a pleasure working with colleagues across species and disciplines on this. Check it out! 👇

Plus, there's now a related conference organized by some wonderful people @unibirmingham.bsky.social in the UK, including @brainapps.bsky.social, @markdhumphries.bsky.social, and others. (Registration for this conference is still open until the 20th October!) uobevents.eventsair.com/the-mechanis...

A little backstory on this one: sometime during the pandemic @hannah-haberkern.bsky.social and I were chatting in the servery at @hhmijanelia.bsky.social about how to encourage interactions between people working on foraging (+ neuroscience) across different species and perspectives... 1/n

Years ago @lauragrima.bsky.social talked about what a pity it is when scientists who work on #foraging miss out on fruitful interactions because they work with different animals. Together with collegues we started a virtual seminar series, which grew into a conference and now a review!

Also want to thank the many people (Janelia foraging conference attendees, future of foraging seminar organizers, and other colleagues) who gave us some great feedback along the way!

Inspired by discussions at several recent foraging-related seminar series and conferences, our review in @cp-trendsneuro.bsky.social explores an expanded role for foraging as a framework in neuroscience and discusses future directions for the field. Do check it out.
