Outline of Final Research Achievements

Focusing on visual modality, I attend to clarify neural basis and mutual nerve communication related to retention of memorandum information, and to establish a method to more accurately capture age-related change of brain activity during retention. From the results of the current source estimation, it was confirmed that the parietal - occipital region involved in the short term retention of visual information, and that activation was enhanced by the memory load. In addition, visualization of time series of visual information processing by dynamics presumption revealed dorsal stream and ventral stream. These results contribute to brain activity estimation technology in terms of data and method development. Generalization of changes in age and individual differences is a future subject.
