Summary:
- Songbirds can grow new brain cells as adults, a process called adult neurogenesis. This allows them to adapt to changes in their environment and learn new songs.
- However, the study found that adult neurogenesis in songbirds can also have a "dark side." Producing new brain cells can make birds more prone to anxiety and risky behavior.
- The findings suggest that the benefits of adult neurogenesis, like increased learning and flexibility, come with potential trade-offs in terms of emotional and behavioral regulation.
