Scoop: NIH is on a mission to enlist one million Americans to share their genetic data to help with health research through a precision medicine program called “All of Us.” What participants don’t know is that at one research site, Palantir stores the data. www.motherjones.com/politics/202...

The profound part of Juneteenth for me is that before this was made a holiday, there was no official celebration of the end of slavery in the United States. When the 13th Amendment passed in December 1865, the legislators who witnessed its enshrinement imagined that the day would be remembered.
We make flexible choices in new situations by knitting together information from separate relevant memories. But what governs which memories are retrieved and when? In a new preprint, we captured how people build decision variables from different memories by tracking their gaze on a blank screen.
Flexible decisions arise from resource-rational memory sampling
Flexible decision making depends on retrieving and recombining memories. Yet because this process unfolds covertly, its governing principles remain unknown. Here we use gaze reinstatement to uncover t...

Ben Saunders@bensaunders.bsky.social · 5mo agoCheck out our latest research drop! We show BLA dopamine signaling encodes the emotional weight of sensory transitions, but not the associative strength or value of stimuli.

New preprint w/ @fredcallaway.bsky.social! How does the brain decide which computations to run? We combine rational meta-reasoning with a meta-learning algorithm to build a recurrent network that learns to select computations. www.biorxiv.org/content/10.6...
Learning to select computations in recurrent neural circuits
Two hallmarks of biological computation are its flexibility and efficiency. These features are often attributed to cognitive control processes that balance external utility against computational cost. However, how the brain could implement such adaptive control remains unknown. Here, we provide one possible answer by combining the computational theory of rational meta-reasoning with a meta-learning algorithm recently proposed as a model of prefrontal cortex. This yields a recurrent neural network model that learns to select computations. In simple choice tasks, the model approximates the algorithms and representations of optimal symbolic models and reproduces neural dynamics observed in macaque orbitofrontal cortex. In multi-step planning tasks, the model replicates key behavioral signatures of human planning strategies and captures human neural dynamics associated with step-by-step mental simulation. Our framework unifies meta-reasoning and meta-learning by showing that learning to reason can be understood as learning to learn from information generated by one’s own cognitive operations, providing a mechanistic account of how adaptive control of thought can be implemented in neural systems. ### Competing Interest Statement The authors have declared no competing interest.

In 2011, my interests in cognitive neuroscience converged on one stubborn intuition: it made no sense that how the brain learns and how it pays attention should be two fundamentally different processes.

Quote from a former colleague: "Good judgement comes from experience. Experience comes from bad judgement."
I was asked to speak with a graduate class today about research data management. I was asked, "How do people become convinced that beginning data management early on in a project is worth it?" Me: "Suffering. They usual have to suffer first." 😅
