Most visual neuroimaging experiments require participants to fixate on a point in the center of the screen during stimulus presentation. This is important because large parts of the visual system are retinotopically organized (a distorted retina-reflecting map). If participants freely move their eyes, the same image stimulates different parts of this cortical map. Eye movements can introduce strong confounds: models may end up decoding eye position on the cortical map and not stimulus-related cortical patterns. There is debate about the strict necessity of fixation though. It also reduces natural viewing behavior and may suppress activity in higher-level visual areas. In general, reconstruction on free-viewing datasets should be approached with caution.
“农民的期盼，就是我们科研工作者攻坚克难的动力。”高德荣代表说，“应对影响农民收入的‘小麦病’，我们尝试在种子内部植入‘抗病基因’，让农民少打药、多打粮，收成更稳当。”经过无数组合、反复试验，该团队育成抗赤霉病品种，不仅抗病能力强，而且产量高。。关于这个话题，51吃瓜提供了深入分析
