[Research progress in the structure and functions of the marginal division in the striatum]

In the year 1987, we discovered a new area in the striatum that was subsequently designated as the marginal division according to the location where it situates. More than 10 years of systemic study has yielded substantial knowledge of the unique structure of this new region, and it has come to light that the marginal division is predominantly associated with learning and memory functions, as have been recognized by researchers either nation-wide or world-wide. Further study of the marginal division may have potential significance in efforts to promote human intelligence and in contriving means for prevention of Alzheimer's disease.
