However, the category-specific cortices for naming famous faces, animals and man-made objects remain controversial. The present study aimed to study the specific areas involved in naming pictures of these 3 categories using functional magnetic resonance imaging. Methods Functional images were analyzed using statistical parametric mapping and the 3 different contrasts were evaluated using t statistics by comparing the naming tasks to their baselines.The contrast images were entered into a random-effects group level analysis.The results were reported in Montreal Neurological Institute co-ordinates,and anatomical regions were identified using an automated anatomical labeling method with XJview 8.Results Naming famous faces caused more activation in the bilateral head of the hippocampus and amygdala with significant left dominance. Bilateral activation of pars triangularis and pars opercularis in the naming of famous faces was also revealed. Naming animals evoked greater responses in the left supplementary motor area, while naming man-made objects evoked more in the left premotor area,left pars orbitalis and right supplementary motor area. The extent of bilateral fusiform gyri activation by naming man-made objects was much larger than that by naming of famous faces or animals.Even in the overlapping sites of activation,some differences among the categories were found for activation in the fusiform gyri.Conclusion The cortices involved in the naming process vary with the naming of famous faces,animals and man-made objects.This finding suggests that different categories of pictures should be used during intra-operative language mapping to generate a broader map of language function, in order to minimize the incidence of false-negative stimulation and permanent post-operative deficits.展开更多

During the Xinhai Revolution, his leadership as the Commander-in-Chief and collaborative efforts with Chen Qimei and other military leaders in restoring Shanghai, re-establishing the Restoration Army to assist rebellious actions in Nanjing and Wuhan, as well as their determination to march northward contributed greatly to the collapse of the Qing government. In its founding years of the Republic, Li retreated from the glory of his political success. Instead of winning him the due respect, however, his well-intentioned and humble act went tarnished by his later forced membership of the Chouanhui, a highly controversial topic in the literature. Adopting the relationship between the Tong- menghui and the Guangfuhui as a point of departure, this paper presents a thorough re-analysis of related historical accounts and various preoccupations surrounding Li, and assumed motivations of his political decisions, so as to reconstruct a truthful image of the debated historical figure.展开更多
