Now to begin to overcome our ignorance of the role of brain chemistry in brain circuitry, it's helpful to work on what we biologists call "model organisms," animals like fruit flies and laboratory mice, in which we can apply powerful genetic techniques to molecularly identify and pinpoint specific classes of neurons, as you heard about in Allan Jones's talk this morning.
现在为了克服我们对大脑化学物质 在大脑回路中的作用的无知， 在我们生物学家称作的 “模式生物”， 比如果蝇和试验鼠等动物身上做试验是有帮助的。 这样我们可以应用强大的基因技术来 分子识别以及 确定具体的神经元的种类， 就如大家今天早上听到 Allan Jones的讲话内容一样。
