英文摘要
Higher brain functions related with consciousness and working memory are investigated using behavioral and fMRI procedures. We found working memory plays a critical role on active consciousness including mental functions like information updating and adjustment. A series of experiments, using fMRI and related psychological working memory task (dual task), suggest that working memory's executive function could be operated based on ACC-PFC neural network in human prefrontal cortex both for verbal and spatial working memory. We found an individual difference in working memory also be fully explained from this network by applying weighted function using a group of high-span and low-span subjects. The results indicate possibility of separating verbal and spatial working memory in terms of activated brain areas using ROI and SEM analyses. WE have published three papers in NeuroImag, one in Behavioral and Brain Research and one in Neuroscience Letters.
