We study how humans explore a 61-state environment with a stochastic region that mimics a “noisy-TV.”
Results: Participants keep exploring the stochastic part even when it’s unhelpful, and novelty-seeking best explains this behavior.

Way back in 1999, Kenji Doya sketched a big picture theory of the brain:
1️⃣The cerebellum is specialized for supervised learning
2️⃣The basal ganglia are for reinforcement learning
3️⃣The cerebral cortex is for unsupervised learning
How does this hold up in 2026? www.sciencedirect.com/science/arti...

We tend to think of neurons as either excitatory or inhibitory, but some neurons chemically inhibit their downstream targets while electrically exciting their neighbors. What is gained by having an inhibitory neuron excite its neighbor?
