Dendrites help neuroscientists see the forest for the trees

Dendritic arbors provide just the right scale to study how individual neurons reciprocally interact with their broader circuitry—and are our best bet to bridge cellular and systems neuroscience.

How artificial agents can help us understand social recognition

Neuroscience is chasing the complexity of social behavior, yet we have not answered the simplest question in the chain: How does a brain know “who is who”? Emerging multi-agent artificial intelligence may help accelerate our understanding of this fundamental computation.
