结论：硝普钠可以抑制脊髓源性神经干细胞的增殖、诱导脊髓源性神经干细胞向神经元的分化。

Conclusions is Sodium nitroprusside can inhibit the proliferation and promote the differentiation of spinal neural stem cells into neuronal but not glial cells in vitro.

而是，它们积累所接收到的能量，只有当积累的能量达到一定临界极限时，它们才会向其他神经元发送自己的能量。

Instead, they sum their received energies, and they send their own quantities of energy to other neurons only when this sum has reached a certain critical threshold.

因为葡萄糖是神经元活动的能量来源，所以大脑中的短暂的葡萄糖低浓度水平会向胃发出信号，让人赶快往嘴里塞食物，纵然能量其实只消耗了九牛一毛。

And because glucose fuels the neurons, a transitory low level in the brain may signal the stomach to get the hands to fill up the mouth, even though the energy actually spent has gone up just a hair.
