Abstract: Objective:To observe the vertical branches and probability of occurrence in cingulate sulcus for providing the anatomical basis in studying the development pattern and relationship between function and structure of cingulate sulcus.Methods:The brain sagittal MRI(7 mm each layer) of 30 volunteers were obtained.The median sagittal MRI imaging of brain were transported into eFilm 1.5, the vertical branches and appearance frequency of cingulate sulcus were observed.Results:The four types(including zero, one, two and three vertical branches) in cingulate sulcus were found according to the paracingulate sulcus appearance.There were side and individual differences in each type.Conclusions:There is obviously side difference in the branch occurrence of cingulate sulcus.Compared with right side, less branch in left side is found, which indicates that the folding degree in fight cingulate sulcus cortex is high than that in left side.
