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.

Machine learning analysis reveals that individual neurons throughout the brain embed information about their anatomical location in their spike trains, a feature that generalizes across animals, experimental conditions, and laboratories.
Studying a decision in archerfish reveals an impressive potential of learning capacities and cognitive aspects that are unexpected for decisions made at reflex speed.
