背景：在功能磁共振成像（fMRI）中精确且同步地呈现范式刺激对于获取有关特定任务所涉及的大脑区域的准确信息至关重要。
新方法：在本文中，我们介绍了一个基于MATLAB的新工具箱——BOLDSync，用于在fMRI中同步呈现刺激。
结果：BOLDSync为功能成像实验中视觉、音频以及多模态视听（AV）刺激的设计和呈现提供了一个用户友好的平台。我们展示了模拟实验，证明了BOLDSync的毫秒级同步精度，并通过在一项视听fMRI研究中的应用说明了BOLDSync的功能。
与现有方法的比较：BOLDSync通过提供一个用户友好且易于使用的界面，在刺激呈现的精确性以及对各种类型刺激设计和系统设置的通用性方面具有优势，从而优于其他现有的专有和开源工具箱。
结论：BOLDSync是fMRI研究中同步呈现刺激的一种可靠、高效且通用的解决方案。（C）2013爱思唯尔公司。保留所有权利。
Background: Precise and synchronized presentation of paradigm stimuli in functional magnetic resonance imaging (fMRI) is central to obtaining accurate information about brain regions involved in a specific task.New method: In this manuscript, we present a new MATLAB-based toolbox, BOLDSync, for synchronized stimulus presentation in fMRI.Results: BOLDSync provides a user friendly platform for design and presentation of visual, audio, as well as multimodal audio-visual (AV) stimuli in functional imaging experiments. We present simulation experiments that demonstrate the millisecond synchronization accuracy of BOLDSync, and also illustrate the functionalities of BOLDSync through application to an AV fMRI study.Comparison with existing methods: BOLDSync gains an advantage over other available proprietary and open-source toolboxes by offering a user friendly and accessible interface that affords both precision in stimulus presentation and versatility across various types of stimulus designs and system setups.Conclusions: BOLDSync is a reliable, efficient, and versatile solution for synchronized stimulus presentation in fMRI study.
