The result is that all the proteins move through the stacker in a tight band just behind the moving front of chloride ions. 这样的结果就是所有蛋白在浓缩胶中压成一条紧密的带，跟在氯离子后面前进。
The secret is engineering them to produce light-activated proteins that pump chloride ions outside of the cells, briefly desensitizing them. 这项工程的秘密在于训练它们产生一种可由光来激活的蛋白质，可以向神经元细胞外面排放氯离子，简单地说，就是降低它们的感光性。
