Neurons in the lateral habenula are activated by pain, bitterness and social defeat, and their responses are dynamically shaped by learning, suggesting a role in experience-dependent selection of behavioral actions to stressors.
Genetic studies in mice reveal the molecular and embryological mechanisms of vocal fold development and function, thereby informing our understanding of vocal communication and congenital voice defects.
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).
Admixture-mediated adaptation to malaria in a human population demonstrates that detectible signatures in genomic patterns of ancestry can be leveraged to better characterize recent selection in populations with mixed ancestry.
Genetic and electrophysiological analyses reveal that the mechanisms orchestrating the induction and expression of homeostatic plasticity are compartmentalized and operate with exquisite specificity on both sides of the synapse.
