Nature research paper: Neural basis of compositional control go.nature.com/4wZQ90D
go.nature.com
Neural basis of compositional control - Nature
Behaviour of human participants in a prey-pursuit task reflects dynamic blending of goal-specific control policies, with hippocampus estimating latent states, anterior cingulate cortex orchestrating policy switches and orbitofrontal cortex supplying value-based contextualization rather than driving continuous policy updating.

US firms that kept DEI policies despite ‘go woke, go broke’ threats thrived
Exclusive: Companies that kept policies did just as well financially, even after Trump’s executive order, as those that didn’t

Hello numerous people who joined and followed! I want to hear your neuroscience takes, but not the same old debates. There's so much we can discuss that's truly new. Here I'll start: -The brain: too big, or not big enough -Most overrated region of cortex -manifolds: isn't just one fold sufficient

Remarkably, Yuefeng Huang, a post doc in Rita Goldstein’s lab at Sinai, started by sharing that SUD is understudied in women compared to men, though it’s well known that risks and tolerance are v different. They’ve designed a cue-reactivity task to capture the sex differences more effectively.

I feel like given today's caloritic availability the brain is too small for our available diets. Our brains could use more folds I feel like they could be something more inkin to a mandal bulb in complexity and design. Also I am not qualified to be giving hot takes on Neuroscience.

I really love these results from the perspective of individual differences in decision making in animals. As a field we assume that animals should be "optimal" in tasks, without questioning what the implications would be evolutionarily if this were actually true (bad, bad implications, see below)
