在这里,我们提出了一个更新的studyforrest(studyforrest.org)数据集,补充了以前发布的功能性磁共振成像(fMRI)数据的自然语言处理与新的两个小时的3特斯拉fMRI采集,而15个原始的参与者显示了视听版本的刺激运动图片。我们证明了两个验证分析,这些新的数据支持建模的特定属性的复杂的自然刺激,以及大量的主体内BOLD响应一致性相关的处理听觉输入,语音和叙事的大脑区域相比,现有的功能磁共振成像数据的音频刺激。此外,我们提供参与者的眼睛注视的位置,同时记录与功能磁共振成像,和一个额外的样本15个控制参与者的眼睛注视轨迹为整个电影记录在实验室设置,使研究注意力的过程和比较调查的潜在影响的刺激设置对这些过程。
Here we present an update of the studyforrest (http://studyforrest.org) dataset that complements the previously released functional magnetic resonance imaging (fMRI) data for natural language processing with a new two-hour 3 Tesla fMRI acquisition while 15 of the original participants were shown an audio-visual version of the stimulus motion picture. We demonstrate with two validation analyses that these new data support modeling specific properties of the complex natural stimulus, as well as a substantial within-subject BOLD response congruency in brain areas related to the processing of auditory inputs, speech, and narrative when compared to the existing fMRI data for audio-only stimulation. In addition, we provide participants' eye gaze location as recorded simultaneously with fMRI, and an additional sample of 15 control participants whose eye gaze trajectories for the entire movie were recorded in a lab setting—to enable studies on attentional processes and comparative investigations on the potential impact of the stimulation setting on these processes.
