This article introduces a model comparing various selection regimes for increasing phenotypic variability. Individuals with the same genotype, reared in id

Neural mechanisms underlying flexible learning and decision-making are not fully understood. Using single-cell calcium imaging, authors here found that neurons in orbitofrontal and secondary motor cortex exhibit complementary roles in reward learning, with neurons in the former exerting a sustained role in conditions of uncertainty.

Odor detection differs fundamentally in vertebrates, which use G protein-coupled receptors (GPCRs), and insects, which employ ion channels. Here, we report the first evidence for a GPCR defining tunin...

Memory is a cornerstone of human behavior, and addiction offers a compelling model of its persistence and plasticity. The scope of engram research has rapidly expanded to include addiction-related ph....

Injectable fluorescent nanoparticles were used to track positions on and inside of freely moving animals at high resolution.
