Excellent ๐Ÿงต on this evening's NIH announcement of a dramatic reduction in indirect rates for research institutions, which amounts to a generational restructuring of the US research and development ecosystem. These cuts are effective immediately, not just for new grants but for existing ones.

After a great conference in Boston, CCN is going to take place in Amsterdam in 2025! To help the exchange of ideas between #neuroscience, cognitive science, and #AI, CCN will for the first time have full length paper submissions (alongside the established 2 pagers)! Info below๐Ÿ‘‡

Random opinion: stochastic optimal control theory is underrated in NeuroAI and theoretical neuro.

It's one of the most general and useful frameworks out there. Lots of beautiful math and solid proofs. More people should apply it to neuroscience... ๐Ÿง ๐Ÿค–

Goal Reduction with Loop-Removal Accelerates RL and Models Human Brain Activity in Goal-Directed Learning Goal-directed planning presents a challenge for classical RL algorithms due to the vastness of the combinatorial state and goal spaces, while humans and animals adapt to complex environments, especial...

Representational spaces in orbitofrontal and ventromedial prefrontal cortex: task states, values, and beyond The orbitofrontal cortex (OFC) and ventromedial-prefrontal cortex (vmPFC) play a key role in decision-making and encode task states in addition to expected value. We review evidence suggesting a conne...
