这两种蛋白质存在于所有神经细胞之中，并能控制在神经间传递信息的化学物质神经传递素的释放。
These proteins are found in every nerve cell and control the release of the chemicals which neurons use to talk to each other, called neurotransmitters.
神经传递素是一种在神经细胞间传递信号的化学物质，在ADHD患者中，这种化学物质常常是指多巴胺，该物质的作用是调节愉悦和满足感。
A neurotransmitter is a chemical that carries messages between nerve cells and, in the case of ADHD, that chemical is often dopamine, which controls feelings of reward and pleasure.
它还和大脑的生理变化相关和一种给大脑和神经传递信号的化学物质的不平衡有关。
It is related to physical changes in the brain, and connected to an imbalance of a type of chemical that carries signals in your brain and nerves.
原因是，一心多用让人感觉很棒，大脑会因为多了一项新的任务而分泌额外的多巴胺（一种影响人们情绪的神经传递素），人们因做每一项新任务而得到了化学物质的奖励。
The reason multitasking feels so good [is that] our brains give us extra shots of dopamine [a brain neurotransmitter that affects mood] for every new task we multitask.
随着时间的推移，它通过消耗神经细胞中一种叫做P物质(或称肽物质，一种神经传递介质)的化学物质来减轻疼痛，该物质使痛觉信号沿神经末梢传递至大脑。
Over time, it short-circuits pain by depleting nerve cells of a chemical called substance p, which helps transfer pain signals along nerve endings to the brain.
例如，法绍尔就认为，领鞭虫目原虫M.brevicollis能靠Munc18/syntaxin1这一对蛋白质隐匿某些化学物质，在很大程度上就象神经细胞释放神经传递素一样。
For instance, Fasshauer suspects M. brevicollis uses Munc18/syntaxin1 to secrete chemicals, much like neurons use it to release neurotransmitters.
人到中年，脑袋的加工处理信息的速度下降，大脑的神经传递素也逐渐衰弱，大脑的一些化学物质也开始走下坡路。
There are declines in processing speed and in neurotransmitters, the chemicals in our brain.
思考神经传递的过程，尤其是那些用以将信号，由神经末梢传递到所支配组织的脑内和身体其他部位的化学物质。
Considers the process of neurotransmission, especially chemicals used in the brain and elsewhere to carry signals from nerve terminals to the structures they innervate.
这些网络中，有许多神经化学物质来协助神经传递工作。
These networks, there are many nerve neurotransmitter chemicals to assist in the work.
这些脑系统都由特定的神经传递物调控，这些化学物质是负责脑部神经元之间讯息传递的。
All these brain systems are modulated by specific neurotransmitters, chemicals that carry messages between the brain's neurons.
深海油鱼富含二十二碳六烯酸（DHA），这是一种omega-3 贮脂肪酸，大脑细胞膜的40%都由这种化学物质组成，它能促进神经传递。
Oily fish are rich in docosahexaenoic acid (DHA), an omega-3 fatty acid that accounts for 40 percent of the makeup of brain cell membranes and which could improve neurotransmission.
