We examined whether the representation held in the short-term memory of simultaneously presented tactile stimuli to fingertips is individual representation or integrated representation between each digit. To determine this, we used the change detection paradigm. In this paradigm, two stimulus arrays are presented sequentially, and observers are required to report whether a change has occurred between them. The performance of this discrimination is assessed as a function of the number of items in the stimulus array so as to determine how many items could be accurately retained in the short-term memory. The results showed that the representation of tactile stimuli to fingertips held in the short-term memory seems to be integrated representation between each digit, after bilateral integration. We believed that this representation is not reflected in topical and fine-scale somatotopy, for example in area 3b of the primate primary somatosensory cortex. It was found that the representation held in the short-term memory of tactile stimuli to fingertips is not a pure replica of the external world.
