  • "Courting a female is more than just motivation," says Beau Alward, Psychological & Brain Sciences PhD student…when it comes to canaries, that is. According to the recent findings by department researchers Dr. Greg Ball & Alward published in Proceedings of the National Academy of Sciences, male canaries not only sang more, but better, with broad brain exposure to testosterone. The male canaries exposed to targeted testosterone also sang more, but their songs weren't as appealing to the females. Their paper, "Differential effects of global versus local testosterone on singing behavior and its underlying neural substrate," suggests that "testosterone needs to act in different areas of the brain to regulate the specific components of this complex social phenomenon." Alward adds, "it appears that, like in so many other species, testosterone in the POM can regulate an animal's motivation, in this case, the motivation to sing. There is the quality of the song that is required to successfully attract a mate and then the process of attending to the female, or singing to her, when she is there which requires the coordination of multiple brain regions." These results may have implications for humans, particularly as it relates to the impact of steroid use on sexual behavior. For more on this research, read the full paper or tune in to the podcast!

  • Infants may not remember what they saw, but they remember that they saw something, according to researchers. "This study addresses one of the classic problems in the study of infant development: What information do infants need to remember about an object in order to remember that it still exists once it is out of their view?" says Melissa Kibbe, Psychological & Brain Sciences Postdoctoral Researcher.
