The metaphor of the brain is tempting, but " neurons" and " synapses" deserve those scare-quotes.

大脑这个比喻听起来很诱人，但是“神经元”和“突触”值得我们引一下。

And the researchers confirmed this is possible.

研究人员证，激活沉默突触是有可能。

SSRIs reduce the reuptake of serotonin, which increases the amount of serotonin hanging around synapses.

SSRIs 减少了对 5-羟色胺再摄取，从而增加了突触周围 5-羟色胺含量。

However, because the bad alpha-synuclein also appears in healthy people, just accumulating it doesn't cause Parkinson's.
