Outline of Final Research Achievements |
Every researcher in neuroscience will agree that the final goal of the study is to understand the human brain. However, due to various restrictions regarding the use of human brains, experimental animals are instead used for sophisticated researches. On the other hand, not so much attention has been payed to detailed structure of the human brain. The present study aimed to find the human brain-specific structures that can be elucidated only by directly analyzing the human brain itself. Complete serial sections were prepared from brain hemispheres, processed for histological studies, and analyzed using computer-assisted three-dimensional tracing system. We found novel modular structures in the human hippocampus that did not exist even in monkey brains. The modules showed periodical patterns inside the hippocampus that have not been described so far. Moreover, we also revealed human-specific structures in the ventral striatum (olfactory tubercle) and in the rostral migratory stream.
