There's a great talk by Juan Gallego on how low-dimensional #NeuralManifolds arise from biological constraints, remain invariant across states and inputs, and support cross-animal alignment. Examples span #HeadDirection rings, #gridcell tori, #MotorCortex prep vs movement, striatal timing dynamics, and C. elegans #behavior loops. Cool talk as it shows how #manifold-level structure can generalize across tasks and organisms.

🐒💭 A psychologist at #Utrecht University tested #chimpanzees at #Uganda’s Ngamba Island Sanctuary in five experiments using boxes and hidden food, finding they weigh evidence and change decisions when confronted with contradictory information. The results suggest rational thinking evolved in our primate ancestors and challenges the assumption that reasoned decision-making defines humanity.

🧠 New preprint by Kim et al. (2025) from David Anderson’s lab: A line #attractor maintains aggressiveness during feeding in “hangry” mice 🍔🐁. Using in vivo #CalciumImaging and #rSLDS modeling, they show how moderate fasting stabilizes an aggression-related attractor in #VMHvl, while prolonged fasting collapses it, linking hunger, motivation, and aggression through #PopulationDynamics:

Fig. 3 | Prolonged fasting duration reveals biphasic effects on aggression and stability of VMHvlEsr1 attractor dynamics.
Fig. 2 | Moderate fasting enhances ramping and persistence in a VMHvlEsr1 latent slow mode.
Fig. 1 | Moderate food deprivation enhances aggression in male mice.

The traditional mechanistic framework must give way to a richer understanding of how #brains actually generate #behavior over time.
Wonderful write-up of the works of Potter, Mitchell, Tse et al. by Luiz Pessoa @PessoaBrain

If you're into #neuroscience at all, you certainly don't want to miss these developments!
