项目摘要

健常者20名を対象に，系列反応時間課題を実施し，反応時間を記録した．また，脳機能計測にNIRS（日立製作所製OT-R41）を使用した．NIRS計測時の課題は，ターゲットタスクを運動学習課題，コントロールタスクを1-2-3-4と規則的な刺激提示に対して対応するボタンを押す課題とした．また，ターゲットタスクとコントロールタスクは各3回試行し，3回のターゲットタスクを加算平均処理し，ターゲットタスク20秒間における各関心領域のOxy-Hb濃度変化を算出した．また，プローブの配置は，国際10-20法でホルダーを装着し，関心領域を左右の眼窩前頭野，前頭極，背外側前頭前野，側頭極，上側頭回，中側頭回，下前頭回，補足運動野とした（Tsuzuki D, 2007）．実験は運動学習前課題，5分間練習，運動学習後課題のプロトコルで実施した．統計解析は運動学習前後の反応速度の変化量を求め，中央値より変化量が大きい群を運動学習高度進行群（以下：高度進行群），小さい群を運動学習中等度進行群（以下：中等度進行群）の2群に分け一般化線形混合モデルによる二元配置分散分析を実施した．反応時間は高度進行群では運動学習前553±25msから運動学習後477±41msへと減少し，中等度進行群では運動学習前542±16msから運動学習後522±25msへと減少した．各関心領域における賦活量は右背外側前頭前野，左前頭眼窩，左右の前頭極において，練習前後と群の交互作用は認めないが運動学習前後で有意な主効果を認め，両群とも同様に賦活量は減少した．

There are 20 normal people, and the series of anti-time problems are applied, and the reverse time records are recorded. The machine can calculate the NIRS (Hitachi Institute of Technology) to use the computer. NIRS program, and to improve the performance of the dynamic learning program. The stimulus prompts for the 1-2-3-4 rule do not cause health problems. Please do so. Each one has three cycles, three cycles, three times, the average value, and the average value of each domain Oxy-Hb in 20 seconds. The international 10-20 method is installed in the front eye field, front pole, back front field, pole, upper loop, middle loop, lower loop (Tsuzuki D, 2007). Training exercise exercise pre-school project, 5 points interval After the study of dynamics, students are required to carry out the exercise. Statistics and analysis of the anti-speed training volume before and after the exercise, the central training volume is very large, and the high level of dynamics is high (following: high-level progressive group). Small population dynamics medium advance group (below: medium progress group) Group 2 population division generalization mixed cluster binary configuration dispersion analysis. Reverse time high performance group dynamics pre-25ms exercise exercise 477 ±41ms training after exercise In the moderate group, 542 ±16ms before and after the exercise, 522 ±25ms decreased. The activity of the right back in the anterior field, the eye in the left, the left and the right in the front, the interaction between the front and the back, the left and the right in the front and the right, the interaction between the front and back of the group, and the intention of the main results before and after the exercise, and the activity of the same group was very low.
