Hatching synchronisation is widespread in oviparous taxa. It has been demonstrated that many species use sounds to coordinate synchronous hatching, being widespread among archosaurs (birds and crocodilians). Recent studies have shown that some turtle species produce vocalisations from within the egg, but the role of this behaviour in synchronising hatch is untested.

In mice, age-related changes in affective behaviors have been reported, but the functional neural circuitry warrants further investigation.
Methods: We assessed age variations in affective behaviors and functional connectivity in male and female C57BL6/J mice.
Article Synopsis
- The study investigates how emotional reactivity in mice changes from youth to late adulthood, focusing on the role of the prefrontal cortex in processing negative stimuli.
- Young mice exhibit more responsiveness to new environments and social interactions, while older mice show varied fear responses.
- Differences in functional connectivity and metabolomic profiles suggest that emotional behavior evolves with age, highlighting the importance of prefrontal-hippocampal connections and specific amino acids in emotionality across the mouse lifespan.
