On the basis of corrosion preparations and of microsphere studies, the following characteristics of the canine and feline cerebral circulation were observed. (1) In cats, a greater part of the vertebral arterial blood goes to the brain and it is more specifically restricted to the ponto-medullary and cerebellar structures. These structures received approximately 3 times more microspheres in cats than in dogs. (2) In dogs, an important amount of vertebral blood goes to the neck muscles, and the intracranial vertebral blood supply is spread over a greater area of the brain, including the thalamo-hypothalamic and posterior cortical zone. (3) In cats the thalamo-hypothalamic area receives a greater amount of blood via the common carotid artery than in dogs. (4) In both animal species, the vascular connections between the left and right side of the brain are more extensive in the vertebral than in the carotid bed. However, for either vascular bed, a more important left to right transmission was found in the dog.
基于腐蚀标本和微球研究，观察到犬和猫脑循环的以下特征。(1) 在猫中，椎动脉的大部分血液流向脑部，且更具体地局限于脑桥-延髓和小脑结构。这些结构在猫中接受的微球比在狗中多约3倍。(2) 在狗中，大量椎动脉血液流向颈部肌肉，颅内椎动脉血液供应分布在大脑的更大区域，包括丘脑-下丘脑和后皮质区。(3) 猫的丘脑-下丘脑区域通过颈总动脉接受的血液比狗多。(4) 在这两种动物中，脑左右两侧之间的血管连接在椎血管床中比在颈动脉床中更广泛。然而，对于任一血管床，在狗中发现从左到右的传输更为重要。
