Administration of dopamine and opioid receptor antagonists resulted in reduced reward anticipation (effort and increased negative facial reactions), but only administration of opioid antagonists resulted in reduced liking (facial reactions).
A new tool to visualize blood-feeding mosquitoes in high resolution and quantitatively characterize their behavior sheds light on contact-dependent sensing and blood-feeding dynamics of several medically relevant mosquito species.
Longitudinal monitoring of poultry farms in southern Vietnam reveals that when outbreaks occur with symptoms similar to highly pathogenic avian influenza, farmers respond by sending their chickens to market early.
Human genomic DNA contains uracil in the late replicating, constitutive heterochromatic regions, while treatment with drugs perturbing thymidylate biosynthesis shifts the uracil distribution pattern towards the euchromatin in UNG-inhibited cells.
Arbitration is formalised as the relative precision of predictions afforded by reward and social learning systems and is represented in modality-specific dopaminergic and dopaminoceptive regions, including the midbrain and amygdala.
