Decision-makers are able to intentionally control neural excitability to strategically bias sensory evidence accumulation towards the decision bound that maximizes reward within a given ecological context.
A mathematical model of bias in marker-gene and metagenomic sequencing measurements explains systematic errors in defined mixtures of microbial species, and enables quantitative and reproducible investigation of biological communities.
A distinct neural network, including the nucleus accumbens as a central hub, is active when rats are exposed to trapped ingroup members they had previously helped escape a trap, but not for outgroup members who had not been helped.
Spatial numerical association in three-day-old domestic chicks linearly decreases as numerical magnitude increases (2>5>8), supporting the hypothesis that numerical magnitude guides the spatial numerical association.
Lysine mono- and di-methylation are two novel post-translational modifications of RNA polymerase II, which are enriched at promoters of active genes, precede lysine acetylation and mark early stages of transcription.
