Figure 3From: Differential sensitivity to the acute and sensitizing behavioral effects of methylphenidate as a function of strain in adolescent and young adult ratsBehavioral responses to injections of methylphenidate or saline in adolescent and early adult Spontaneously Hypertensive, Sprague Dawley, and Wistar Kyoto rats across the 10 pretreatment days. Filled symbols represent methylphenidate-treated animals. Open symbols represent saline-treated animals. Circles, squares and triangles represent Spontaneously Hypertensive, Sprague Dawley, and Wistar Kyoto rats, respectively. Adult SHR group pretreated with methylphendiate, n = 5. All other groups, n = 6. Please see text for statistical results. SHR: Spontaneously Hypertensive rat; SD: Sprague Dawley; WKY: Wistar Kyoto; MPH: methylphenidate; Sal: saline.Back to article page
