Why Is Terje Sagvolden Influential?
(Suggest an Edit or Addition)According to Wikipedia, Terje Sagvolden was a Norwegian behavioral neuroscientist, a professor at the Universities of Oslo and Tromsø, and adjunct professor at the University of Maryland, Baltimore County. Research Sagvolden's research career started with his work for his PhD, which he obtained in 1979 from the University of Oslo based on a thesis entitled Behavioral Changes in Rats with Septal Lesions: Effects of Water-Deprivation Level and Intensity of Electrical Shocks. Sagvolden is best known for the discovery that the SHR rat strain is hyperactive. Over the next decades, he then went on to demonstrate that this strain is a valid animal model for attention deficit hyperactivity disorder . Subsequently, Sagvolden also showed that the WKY/NCrl rat strain showed inattention, but no impulsivity or hyperactivity, and validated this strain as an animal model of inattentive ADHD. Over the course of his career, Sagvolden worked not only with rats, but also with humans and pigeons.
