If your lover's singing is sometimes sexy and sometimes annoying, a change in hormones may be the reason.
A songbird study led by Donna Maney,assistant professor of psychology and a member of the Graduate Program in Neuroscience at Emory University, says it sheds new light on this issue, showing that a change in hormone levels may alter the way we perceive social cues by altering a system of brain nuclei, common to all vertebrates, called the "social behavior network."
Their research examines how genes, hormones and the environment interact to affect the brain, using songbirds as a model and helps provide an understanding of the basic principles underlying brain structure and function common to many species, including humans.
