Hormonal manipulation, laser microdissection, and bulk RNA sequencing indicate that Z chromosome dosage in the brain region HVC during development regulates the subsequent sexually dimorphic transcriptional specialization of zebra finch song nuclei.
Exposure to a real-life adversity, such as the COVID-19 pandemic, reduced the optimism bias typically observed in belief updating about future life events, shifting behavior toward more rational, Bayesian-like learning.
