🐒💭 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.

Chimps Can Revise Their Beliefs When Shown New Evidence, Study Finds

Chimpanzees can change their minds when the facts no longer support their previous beliefs – a rational level of thinking that was once considered uniquely human.

🧠 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:

A line attractor maintains aggressiveness during feeding in “hangry” mice

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.

"Beyond Newtonian causation in neuroscience: Embracing complex causality."
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!
