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.
背景
在功能磁共振成像（fMRI）中精确且同步地呈现范式刺激是获取关于特定任务所涉及的脑区的准确信息的关键。
新方法
在本文中，我们提出了一种新的基于 MATLAB 的工具包 BOLDSync，用于 fMRI 中的同步刺激呈现。
结果
BOLDSync 为视觉、音频以及功能成像实验中的多模态视听（AV）刺激的设计和呈现提供了一个用户友好的平台。我们呈现了模拟实验，展示了 BOLDSync 的毫秒级同步精度，并且通过应用于 AV fMRI 研究来说明了 BOLDSync 的功能。
与现有方法的比较
BOLDSync 通过提供用户友好且易于访问的界面，在刺激呈现的精确性和各种类型的刺激设计和系统设置的多功能性方面，优于其他现有的专有和开源工具包。
结论
BOLDSync 是 fMRI 研究中同步刺激呈现的可靠、高效且多功能的解决方案。
