Thrilled to share this work, long time in the making! Carried through creatively by @siddjakes.bsky.social after initial design & piloting by @trackingskills.bsky.social, with help from @trackingactions.bsky.social. Modeling in collaboration with Massimo Vergassola & Nicola Rigolli.
Mice navigate scent trails using predictive policies
Animals actively sense their environment to extract features of interest to guide behaviors. For mammals, odors are prominent environmental features which are sampled by active modulation of sniffing ...

Differential kinematic coding in sensorimotor striatum across behavioral domains reflects different contributions to movement - Nature Neuroscience
Hardcastle and Marshall et al. show that striatal function is domain specific, required for task-related but not spontaneously expressed movements. This functional distinction is reflected in starkly ...

Sam Gershman writes beautifully about how theory-free neuroscience prevents the field from reaching its promise. Beautiful and true. Most folks do not test hypotheses. Running a NHST does not a hypothesis make. www.thetransmitter.org/theoretical-...
Breaking the barrier between theorists and experimentalists
Many neuroscience students are steeped in an experiment-first style of thinking. Let’s not forget how theory can guide experiments.

1. Today the NIH director issued a new directive slashing overhead rates to 15%.
I want to provide some context on what that means and why it matters.

The NIH overhead cut doesn't just hurt universities.
It's deadly to the US economy.
The US is a world leader in tech due to the ecosystem that NIH and NSF propel. It drives innovation for tech transfer, creates a highly-skilled sci/tech workforce, and fosters academic/industry crossfertilization.

2. While NSF and NIH indeed have a mission to fund specific research innovations via grantmaking, they do a lot more than that.
Their principal role is support a scientific ecosystem in the United States, that includes everything from education and training to infrastructure and communication.
