The ventricles of the brain in the N. American mink (Mustela vison (Brisson, 1756)).

Using anatomical as well as radiographic and tomographic methods, sixty brains of the N. American mink were examined. It was found that the brain consists of four ventricles. Also, it was noted that the posterior horn was missing and that there was the olfactory recess present in the lateral ventricle, a large-size interthalamic connection present in the third ventricle, and a flat, necklace-like bottom in the fourth ventricle. Only recently, the ins and outs of the mink's anatomical structure have begun to absorb anatomists. Apparently, it is related to the fact that furry animals, among them the mink, are being domesticated as if "before our eyes". For this reason and because of the easy access to material, examining of the brain ventricles in the mink was taken up.
