Sperry showed that the regenerated retinal axons always innervated the original sites of termination in the optic tectum. This experiment strongly disprove the resonance hypotheses proposed by Paul Weiss, who suggested that the nerve growth and synapse formation are largely random events, and the precision of connections between nerve cells emerged by selectively eliminating the inappropriate connections, only at later developmental stage.

Sperry的实验在支持Cajal假说的基础上，进一步明确发育过程中轴突的生长及突触的形成具有内在决定性，并且有力地反驳了当时占主流地位的由Paul Weiss于1930～40年代提出的resonance hypothesis，后者认为轴突的生长和突触的形成大多是一些随机事件，成年脑中的精确联系是通过对随机形成的不恰当联系进行选择地消除形成的。

long-term memory：长期记忆

记亿可以分为两种,长期记忆(long term memory)与短期记忆(short term memory). 目前认为,长期记亿的形成牵涉到神经细胞突触的变化,而此变化是需要在突触区域合成新的蛋白质,如果抑制突触区域的蛋白质合成,就会抑制长期记忆的形成. 换言之,

synapse：神经元突触

因为记忆是要靠在大脑皮层的神经元突触(synapse)增生形成网络. 而这个过程正是主要在睡眠中进行的. 所以千万不要养成熬夜的习惯. 就算只在考试前熬夜,都只会对脑部表现产生反效果. 总的来说,能令身体健康的习惯,都对智能发展有益,
