PurposeTo评估的可重复性的大脑激活和眼球运动模式的扫视范式比较科目时，任务，和磁共振（MR）systems.Materials和MethodsForty-5健康成人在两个不同的网站（n= 45）进行扫视任务与不同水平的目标可预测性：可预测（PRED），位置可预测（pPRED），时间可预测（tPRED），和prosaccade（SAC）。用重复测量方差分析测试眼动模式。激活地图的可重复性估计与集群重叠Jaccard指数和信号方差系数的决定内受试者测试-重测数据，并为受试者之间的数据从相同和不同的sites.ResultsIn所有组lasting增加与降低目标的可预测性：PRED < pPRED < tPRED < SAC（P<0，001）。在受试者内重测比较中，所有任务的激活重叠均为良好至一般（>0.40），而不同受试者的tPRED则较差（<0.40）。组内数据的不同任务重叠（0.40-0.68）高于组间数据（0.30-0.50）。相同受试者的激活一致性为60-85%，不同受试者为50-79%，不同部位为50-80%。在SAC中，在相同和不同受试者中发现的激活比其他任务（50-80%）更加一致。ConclusionThe predictive saccade tasks produced evidence for brain‐activation and eye‐movement reproducibility.J.

PurposeTo assess the reproducibility of brain‐activation and eye‐movement patterns in a saccade paradigm when comparing subjects, tasks, and magnetic resonance (MR) systems.Materials and MethodsForty‐five healthy adults at two different sites (n= 45) performed saccade tasks with varying levels of target predictability: predictable (PRED), position predictable (pPRED), time predictable (tPRED), and prosaccade (SAC). Eye‐movement pattern was tested with a repeated‐measures analysis of variance. Activation maps reproducibility were estimated with the cluster overlap Jaccard index and signal variance coefficient of determination for within‐subjects test–retest data, and for between‐subjects data from the same and different sites.ResultsIn all groups latencies increased with decreasing target predictability: PRED < pPRED < tPRED < SAC (P< 0,001). Activation overlap was good to fair (>0.40) in all tasks in the within‐subjects test–retest comparisons and poor (<0.40) in the tPRED for different subjects. The overlap of the different tasks for within‐groups data was higher (0.40–0.68) than for the between‐groups data (0.30–0.50). Activation consistency was 60–85% in the same subjects, 50–79% in different subjects, and 50–80% in different sites. In SAC, the activation found in the same and in different subjects was more consistent than in other tasks (50–80%).ConclusionThe predictive saccade tasks produced evidence for brain‐activation and eye‐movement reproducibility.J.
