The aim of this study was to explore the objective and subjective influences of road noise on individuals' attention stability in learning spaces along the *** road noise was divided into three typical levels,namely low 55 dB,medium 65 dB,high 75 dB,based on the field survey data of 21 roads of 10 typical schools in the high-density city,Shenyang,*** simulate the interference of road noise on learning spaces,audios of three typical levels recorded in actual environments were played in laboratory,with their SPL reduced to low-45 dB,medium-55 dB,high-65 dB,*** tests were conducted on 20 undergraduate student participants by visualtracking tasks and a telemetry eye tracker was used to record the eye-movement *** task took pictures with multiple interlacing curves as experimental materials,and participants were asked to track the curves with their eyes and speak out the number and the letter connected by one *** that,participants need to fill the questionnaire to assess the subjective interference degree during the test."Accuracy","Reaction time","The average number of fixation points " were taken as the objective indicator of attention."The degree of interference" was the subjective indicator of *** experiment used within-participants design to eliminate the influence of individual *** square design was taken to avoid the order *** were arranged to practice in advance to avoid the practice *** results showed as follows:(1) there were significant differences on the objective indicators(the accuracy:F=4.692,P=0.013<0.05;reaction time:F=6.813,P=0.017<0.05;the average number of fixation points:F=4.171,P=0.023<0.05) and the subjective interference degree(F=22.47,P=0.000<0.05) under the influence of three typical levels of road noise.(2)The Pearson correlation analysis showed that there is a weak correlation between the degree of subjective interference and the correct rate(P=0.031 < 0

Deep brain stimulation (DBS) is a effective treatment method for patients with Parkinson's disease (PD). In this study, a quantitative evaluation for the availability of DBS operation to PD patients were done by use of a visual tracking test. visual target with random trajectory was adopted and the hand movement of three PD patients were recorded in the state before and after surgery. Parameters related to the tremor, rigidity, akinesia and so on were calculated and the effect of DBS operation was quantitatively evaluated. Remarkable improvement was validated through the parameters. In addition to the above analysis, comparison of the motor function between PD patients and normal healthy person was also investigated.

Skillful motor control of human is achieved by the appropriate motor commands generating from the central nerve system. Internal model in the cerebellum may have great contribution for realizing accurate motor control. In this paper, the model for human motor control on manual tracking to moving visual target was constructed based on the experimental data of the visual tracking test for three groups; normal healthy adults, patients with cerebellar ataxia and patients with Parkinson disease. Relationship between the model parameters and movement disorders were investigated. Furthermore, the compensation method for improving the motor function of patients were also considered.
