The ability to distinguish between similar memories depends on a tiny strip of brain tissue called the dentate gyrus.

区分相似记忆能力依赖于小块被称为齿状回脑组织。

They injected a mixture of chemicals into a part of the mice's brains involved in memory formation called the dentate gyrus.

他们化学物质混合物注入小鼠大脑中与记忆形成有关部分，称为齿状回。

Studies in mice have shown that the dentate gyrus is one of the few bits of the brain to generate new neurons even in adulthood.

对老鼠究表明，即使在成年后，齿状回也是大脑中少数几个会产生新神经元部位之。

After being injected, the cells in the dentate gyrus would begin to produce channelrhodopsin-2, making the cells themselves sensitive to light as well.

注射后， 齿状回中会开始产生 channelrhodopsin-2，使本身也对光敏感。

The antis argue that either humans do not grow these neurons in the dentate gyrus, or if they do, there are too few of them to be useful.

反对者认为，要么人类在齿状回中不生长这些神经元，要么即使生长了，它们也太少了，无法发挥作用。

Then evidence began to emerge of young neurons in the brains of adult rats and mice, -specifically in the olfactory bulb, which processes smell, and the dentate gyrus.

随后，成年大鼠和小鼠大脑中出现了年轻神经元证据，特别是在处理气味嗅球和齿状回中。

Radial gates control how much water is released and massive  concrete blocks at the bottom of the chute, called dentates, disperse the flow to reduce erosion as  it crashes into the Feather River.

径向闸门控制释放水量，滑槽底部巨大混凝土块（称为齿状）可以分散水流，以减少水流流入羽毛河时侵蚀。
