Abstract

An investigation was conducted into the differences between macrosmatic and microsmatic animals of arterial supply in the area of the olfactory trigone and the anterior perforated substance. A brain of domestic cat was taken as an example of a macrosmatic animal and a brain of baboon as an example of a microsmatic animal. The cerebral blood vessels of the cadavers of 30 cats and 11 baboons were filled with latex and, after fixation in acid alcohol by means of microscopic operation, the cortical and deep branches of the anterior and middle cerebral arteries were dissected.
We discovered that there were differences between these two groups of animals in the places of arising of deep branches and in their course. In the cat the deep branches running through the area of the olfactory trigone arose from the beginning part of the middle cerebral artery in numbers 5–10 and entered the brain in the olfactory tubercle. In the baboon the deep branches arose from two sources: the middle cerebral artery and the anterior cerebral artery. The branches of the middle cerebral artery went through the anterior perforated substance, forming two groups of branches: lateral and medial.
