Comparative MRI between chimpanzees and humans Article Summary

CC is directly related to a wide range of neuronal functions. The conclusion of the study is that the differences in the development of the CC and CC subdivision such as rostrum and the rostral body between the two species are related to brain system evolution changes that occur in the two species. The participants of the study were four chimpanzees among them being three females and one male. The age range of the chimpanzees was 1. 8 to 72 months. T1-weighted, three-dimensional, whole brain images of the humans had been acquired using the 1. 5 Tesla MR image. The midsagittal CC regions in the images of each participant were assessed using the Analyze 9. 0 software for result generation. In result measurement, the total CC was subdivided into CC subdivision such as rostrum and the rostral body for reliability.

Human beings have a greater tendency of the increment of the CC both at infancy and at the juvenile stage. Based in the methodology, the analysis, and the results of the study, it is apparent that the researchers were able to reach their primary objective and which was to validate the differences between the CC developmental path between humans and chimpanzees from the stage infancy through juvenility. The researchers, however, did not give a clear discussion of the impacts that the differences in the overall behavior and neuronal functioning of the two species. Though the researchers gave an implication that the differences in the development of the CC and CC subdivisions between the two species are related to brain system evolution changes that occur in the two species, they did not give a clear definition of how the differences directly impact that brain system evolutional changes of both species.
