A different stain marks nerve cell fibers (bottom), revealing heavy staining in the central region where nerve fiber tracts connect one region of the brain to another.

用一种不同的着色剂标示出了神经细胞纤维(底部)，图中中部着色很重的区域是神经束将大脑的各个不同部位进行连接的部位。

Most of this energy goes towards maintaining synapses, the junctions across which impulses jump from nerve cell to nerve cell, keeping the brain alert even when it is not doing anything.

其中大部分用来维持突触，让大脑即使在无事可做时也保持警觉。突触是神经细胞间的连结，脉冲信号通过它们在细胞间传导。

The male brains, especially nerve cell rich parts of the brain associated with thinking and remembering, seemed to have sustained more long term damage from high lead levels than the brains of the young women.

Nerve-cell precursors can turn into two types of brain cell besides nerve cells.

It is also backed up by work done on both people and laboratory animals, which shows that stress changes the activity of neurotransmitters, the chemicals that carry signals from one nerve cell to another in the brain.

The other concept, pursued by Pfizer, Japan's Ono Pharmaceutical, the AstraZeneca-Renovis partnership and numerous other firms, is to find a brain-cell protector that could be used to stabilize nerve cells and prevent further damage.
