 It is considered that humans have evoked a specialized network in their left hemisphere when using tools with the right hand. Although chopsticks are familiar tableware in daily living and consist simply of only two slender sticks, they demand a highly advanced and elegant skill when they are manipulated properly. The aim of this study was to investigate the functional brain areas associated with manipulation of the chopsticks. An H215O positron emission tomography (PET) was performed using 6 normal volunteers to measure regional cerebral blood flow during picking a small object repetitively. The results showed significant activation of the primary motor area (M1), primary sensory area (S1), premotor area (PM), superior parietal lobule (BA7), inferior parietal lobule (BA39/40), visual cortex (BA17/18/19), vermis, dentate nucleus, paramedian lobule and hemispheres of the cerebellum.
