The rats that had spent more time in the enriched environment had more synaptic connections.

（后来发现）在丰富的环境中待得时间长的老鼠具有更多的突触连接。

The hippocampus then encodes memories, probably by strengthening the synaptic connections stimulated during the original sensory experience.

杏仁核所着重的是 和强烈情绪有关的经验。接着，海马回会把记忆编码，做法可能是将原始感官经验过程中。

They then monitored each network during training, recording neuronal activity and the strength of synaptic connections.

然后， 他们在训练期间监控每个网络，记录神经元活动和突触连接的强度。

If you try and learn a language, regardless of your age, synaptic connections are made, which ultimately create a denser grey matter and stronger white matter networks.

如果你试着学习一门语言，不管你的年龄如何，（你大脑的）突触连接就会建立起来，最终形成一个更密集的灰质和更强大的白质网络。

Pictures are fed into the first layer of the network, which sends information about the content of each pixel to the next layer through the AI equivalent of synaptic connections.

图片被输入到网络的第一层，网络通过相当于人工智能的突触连接将每个像素内容的信息发送到下一层。

The outcome, published this week in Nature, is a model which paints a detailed picture of a female fly's brain with 139,255 neurons, and locates some 54.5m synaptic connections between them.

研究成果于本周发表在《自然》杂志上，该模型详细描绘了雌性苍蝇的大脑， 其中有 139,255 个神经元，并确定了它们之间的约 5450 万个突触连接。

Too much of it results in the loss of synaptic connections between neurons and the shrinking of your prefrontal cortex, the part of your brain the regulates behaviors like concentration, decision-making, judgement, and social interaction.

过多的皮质醇导致神经原之间突触连接减少，和你额叶前部皮质层的萎缩。这是你大脑里管理精力集中、决策制定、判断，和社交互动的部分。
