This study introduces RMAs, synthetic serum markers that enable noninvasive monitoring of gene expression in primate brains via blood tests over three months.

The paper analyzes transcriptomic diversity in amygdalar subdivisions across humans and nonhuman primates using single-nucleus RNA sequencing and identifies distinct neuronal subtypes and transcriptional specializations.

This study investigates how curiosity and hedonic valence influence reinforcement learning in rhesus macaques, finding that novelty seeking is driven by optimistic priors rather than valence-dependent curiosity.
