fMRI signals are noisy. Many reconstruction-oriented datasets therefore include many repeated presentations of the test stimuli (resampling). Averaging across repetitions improves signal quality (SNR) and makes voxel-level patterns more reliable. Single-shot reconstruction is rarely seen outside invasive (implant) recording contexts and even there often produces substantially lower quality than reconstructions from resampled stimuli. If your pipeline is strong enough, however, it is worth trying.

那时候我躲在家里，能清楚听到轰炸机从头顶飞过，先是“咻”的一声，接着就是“嘣”的爆炸声。我抱着四岁的儿子躲在我觉得最抗震的楼梯间，一边发抖，一边听着炮弹落下的声音，估算着距离有多远，等着下一声巨响。那种感觉真的太可怕了。
