查询词典 optic

Retinotopic inputs to the optic tectum have been thoroughly mapped, but now Sato et al. map tectal efferents that project to the premotor reticulospinal system of the hindbrain.

视网膜区域定位输入信号到视顶盖已经得到了充分的定位，现在Sato等人绘制了覆盖层传出神经，它们投射到后脑的网状脊髓系统。

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。

T was later transiently expressed in pharyngeal arches, and in pectoral fin buds. IGFBP-3 mRNA is predominantly and persistently expressed in the developing otic vesicle. IGFBP-3 is also expressed in optic stalk, retina, pineal gland, tegmentum in midbrain, anterior pituitary and midline floor of hypothalamus.
