<p><b>新页面</b></p><div>'''下丘'''（Inferior colliculus，来源于拉丁语，字面意思为“下方的小山”）是[[中脑顶盖]]部的[[神经核]]团，左右各一，关于中线对称。下丘与[[上丘]]一起组成所谓的“[[四叠体]]”，是[[中脑]]背侧[[顶盖]]部一个显著的[[解剖]]结构。下丘是[[听觉通路]]的一个重要组成部分。它接受所有位于[[脑干]]的下级[[听觉]]核团的输入，并向上投射到[[丘脑]]的[[内侧膝状体]]（Medial geniculate nucleus，MGN）。<br />
<br />
== 与听觉通路其它部分的关系 ==<br />
<br />
在中脑，下丘的位置在上丘这一关键性[[视觉]]核团的下方。下丘是来自背侧[[耳蜗]]核（DCN）的纵向[[听觉定位]]信息与来自[[上橄榄核]]的横向听觉定位信息最先整合的部位，从而下丘在声音的[[空间定位]]功能中扮演重要角色。<br />
<br />
下丘大致可以三个子部，包括，'''[[中央核]]'''（Central nucleus，简称'''CNIC'''），'''中央旁核'''（Pericentral nucleus），和'''外核'''（External nucleus）。<br />
