Location, Location, Location: Testosterone Acts in Different Brain Regions to Regulate Distinct Features of the Same Behavior
Material below summarizes the article Pleiotropic Control by Testosterone of a Learned Vocal Behavior and Its Underlying Neuroplasticity, published on January 12, 2016, in eNeuro and authored by Beau A. Alward, Farrah N. Madison, Shannon E. Parker, Jacques Balthazart, and Gregory F. Ball.
Adaptive variation in behavior often involves dynamic changes in different brain regions (neuroplasticity) that form a regulatory circuit. Steroid hormones can profoundly modulate behavior in multiple ways: generally, such as alteration of arousal, or specifically, such as enhancing a particular sensory experience.
The results from our study highlight these actions of testosterone on a complex behavior and its underlying neuroplasticity.
