Background : Clinical assessment using the pegboard task has been quantitatively evaluated in terms of time required and amount of work, but it has not been qualitatively evaluated from the movement of the upper limb and fingers. The purpose of this study was to clarify the required ability for motion adjustments of the upper limb and fingers when transport-to-insertion task is performed. Methods : A total of 51 healthy volunteers (aged 22.3±3.8) were studied. They performed tasks involving pulling a peg from a near-side hole and inserting it into a far-side hole under three conditions : no obstacle, obstacle on the lateral side, and obstacle on the front side. The motion of upper limb and fingers were measured with a three-dimensional ultrasound motion analyzer, and 15 parameters were measured. Ability of motion adjustment was evaluated by factor analysis of related parameters in each condition. Results : In the no-obstacle condition, the important factors were adjustments of finger motion at transport phase (TP), wrist and finger motion at insertion phase (IP), vertical trajectories, timing and speed of the task. When obstacles were present, in addition to factors that were required in the no-obstacle condition, additional adjustments of the wrist motion at TP and horizontal amplitude were required. Conclusion : In the transport-to-insertion task, different ability of motion adjustment was required depending on the task conditions. The results of this study may provide useful basic data for assessment of dexterity from the qualitative aspect using the pegboard task. ãèæ¯ããã°ããŒããçšããèšåºè©äŸ¡ã¯ãäœæ¥éãæèŠæéãšããéçåŽé¢ããã®è©äŸ¡ãå€ ããäžè¢ææã®åãæ¹ã«é¢ãã質çåŽé¢ããã¯è©äŸ¡ãããŠããªããæ¬ç 究ã®ç®çã¯ããã° ããŒã課é¡ïŒéæ¬ã»æ¿å

However, somepatients have difficulty in returning to their professional lives after right frontal lobedamage, even though they do not have language or motor deficits. Recent developmentsin neuroimaging methodologies have increased our understanding of neuropsychologicalfunctions and networks, and have shown that the right frontal lobe plays critical roles insocial life, including working memory, visuospatial cognition, mentalizing, and attention.This review presents a summary of recent findings regarding right frontal lobe functionsand their neural networks focusing on the above four functions

In this study, we revealed the following results. The prefrontal to posterior prefrontal regions were involved in the understanding of all basic emotion recognition. On the other hand, the medial prefrontal cortex played a central role in happiness and the orbitofrontal cortex in the inferior frontal gyrus plays a central role in sadness, and when these regions were damaged, happiness could be recovered but sadness is not. The researchers also found structures where nerve fibers converge, which existed in approximately 300 locations throughout the brain. This anatomical structure might explain the functional recovery from brain damage.ç 究課é¡/é åçªå·:18H03126, ç 究æé(幎床):2018-04-01 - 2021-03-31åºå

In this study, we used the techniques of awake surgery, statistical analysis of images, and fiber dissection to clarify the functions and regions of the brain involved in inhibition. We found following results: the medial prefrontal cortex and the orbitofrontal region of the inferior frontal gyrus were involved in the inhibition of emotional understanding, Zone II of the cingulate gyrus related to control of attention, and the posterior component of the frontal aslant tract was involved in the control of movement. Emotional recognition was markedly different due to damage to areas involved in inhibition. For attention and motor functions, damage to the inhibitory regions caused attention deficits and transient paralysis, respectively. The results of current study may be applicable to rehabilitation programs.ç 究課é¡/é åçªå·:19K22801, ç 究æé(幎床):2019-06-28 â 2021-03-31åºå

Then correlation between movement time of tapping movement and score of purdue pegboard test were calculated. Study 2: We studied intraoperative characteristic motor symptom, namely disturbance of coordination movement, of patients with brain tumor located in the supplementary motor area. This study demonstrated that the tapping movement may be useful clinical evaluation of qualitative aspects of coordination movement, namely timing, grading, and placing.ç 究課é¡/é åçªå·:25750199, ç 究æé(幎床):2013-04-01 - 2016-03-3

We performed following two process; 1) To analyzed relationship between white matter tract and mentalizing score, we used neulo-imaging methods including voxel-based lesion symptom analysis and tract-wise lesion symptom analysis. 2) Then, mapping sites of mentalizing assessment during awake surgery were plotted on standard brain, and were analyzed. Consequently, we revealed that different white matter tracts were involved in high- and low-level mentalizing process: the right arcuate fascicles involved in low-level mentalizing, while, the third branch of the superior longitudinal fascicles and fronto-striatal tract were related to high-level mentalizing.ç 究課é¡/é åçªå·:16K16422, ç 究æé(幎床):2016-04-01 - 2019-03-3
