主 题:brain activation fMRI human brain inferior parietal lobule light grasp mirror neuron system powerful grasp
摘 要:Mirror neuron system can be activated by observation and execution of an *** has an important function of action *** investigated brain activations in humans by observing the strength of a hand grasp using functional magnetic resonance *** right-handed healthy individuals,consisting of 10 males and 10 females,aged 22.40 ± 2.04 years,were recruited into this study from September to November 2017 via *** hand grasp task video showed a hand lightly grasping and releasing a ball *** hand grasp task video showed a hand tightly grasping and releasing a ball *** magnetic resonance imaging block design paradigm comprised five stimulation blocks alternating with five baseline *** blocks were presented with two stimulus tasks,consisting of a light grasp and a powerful *** of interest was defined around the inferior parietal lobule,inferior frontal gyrus,and superior temporal sulcus which have been called mirror neuron *** inferior parietal lobule,fusiform,postcentral,occipital,temporal,and frontal gyri were activated during light and powerful grasp *** BOLD signal response of a powerful grasp was stronger than that of a light *** results suggest that brain activation of the inferior parietal lobule,which is the core brain region of the mirror neuron system,was stronger in the powerful grasp task than in the light grasp *** believe that our results might be helpful for instructing rehabilitation of brain *** study was approved by the Institutional Review Board of Daegu Oriental Hospital of Daegu Haany University on September 8,2017 (approval ***-D-17020-PRO-01).
