Ever wondered why birds sing in spring?
March 27, 2008
A team of international researchers succeeded in tracing the changes in the bird’s brain. They believe it is “because of hormonal changes”, during the longer days, birds know to sing during spring.
Prof. Peter Sharp, lead researcher, of the Roslin Institute in the United Kingdom said, “While we knew what area of the brain was affected by seasonal change, until now we did not know the exact mechanism involved. Now we have identified a key element in the process of brain’s activity when spring arrives.”
But for advances in technology this break through would have remained a far cry, as the new technology enabled researchers to scan thousands of genes so to work out, which ones are affected by seasonal changes.
