[Arterial vascularization of the amygdaloid body in man].

The arterial supply of the amygdaloid body was studied on 20 brains of adult individuals of both sexes. The middle cerebral and anterior choroidal artery were selectively injected with a mixture of India ink and 5% gelatin solution. By injecting the middle cerebral artery, we filled the blood vessels of the putamen, the lateral part of globus pallidus, the internal capsule, claustrum, insular cortex and the cortex of the convex side of the hemisphere, whereas the blood vessels of the amygdaloid body remained unfilled by the mixture. By injecting the anterior choroidal artery, the blood vessels of the medial part of globus pallidus and of the amygdaloid body were filled, except in one case, when the blood vessels were filled only in it's posterior part. Based on the results obtained, a conclusion may be drawn that the branches of the anterior choroidal artery play the main role in the amygdaloid body arterial supply.
