There is a crossover and this is important when we think about the studies that will follow but the crossover is that everything you see in the left visual field goes to the right side of your brain; everything in the right visual field goes to the left side of the brain, and similarly, there's a crossover in action.
大脑中存在着交叉,这对于我们考虑下面的一些相关研究,是非常重要的,交叉是指呈现于你左视野中的刺激,会投射到你的右脑,呈现于你右视野中的刺激,会投射到你的左脑,同样,行为上也存在着交叉的关系
