We know that stimulation helps to increase connections within the brain
我们知道感官刺激能增强大脑内部联系，
that speed the flow of information around the brain,
从而加速信息在大脑中周转的速度，
but there have been relatively few studies of the impact of a reduction in sensory stimulation.
但是对感官刺激减少所产生的影响，我们研究得比较少。

So it's quite a useful thing to see whether you get a reduction in that ability to process information effectively.
因此我们的研究非常有实际意义，它能揭示人有效处理信息的能力是否下降。
