title: Differences in localization of substantia nigra vs interaural line in Wistar and Sprague Dawley rats.
abstract: The position of substantia nigra anterior to the interaural line has been correlated with body weight in Wistar rats. A regression line y = 0.0050x + 1.36 makes it possible to locate the substantia nigra in different sized rats ranging between 140 g and 460 g. This equation is not valid for Sprague Dawley rats. The position of bregma anterior to the interaural line has also been examined. A fairly good correlation was found for sprague Dawley rats while the position of bregma in Wistar rats was much more variable.
