Investigations in vivo and in vitro have elucidated the following: IL-2 and IL-2R have been detected in the brain; IL-2 promotes survival and neurite extension of cultured neurons, stimulates oligodendrocyte proliferation and maturation, affects the hypothalamic-pituitary function and produces behavioral and electrocorticogram spectrum changes.

研究表明IL-2在脑中主要存在于海马、下丘脑、小脑、前额皮层、纹状体、膈以及蓝斑等脑区。

Our simulation results show that in some cases, the network model can generate the spindle waveform which is an electrographic mark for falling asleep. This results may enlighten us that it is possible to use the simulation results of these models to search for the further sleeping mechanism and the information processing about how the microscopical electric activities in billions of synaptically coupled neurons can be integrated to the macroscopical function states by synchronized oscillations in human brain.

这一网络模型的仿真结果，在一定条件下，确能在皮层细胞处出现符合睡眠分期中规定的标志入睡的纺锤波，这一初步结果，启示我们用模型仿真方法来进一步探讨睡眠机制和用模型仿真方法来进一步探讨人脑的微观神经元的电活动是如何通过同步振荡整合到宏观功能状态的某些信息处理过程的可能性。
