促进睡眠的腹外侧视前区 (VLPO) 的最大突触输入来自外侧下丘脑,这是一个与觉醒相关的大脑区域。然而,LH 内大多数 VLPO 投射神经元的神经化学特性以及它们在唤醒网络中的功能仍然未知。在此,我们描述了 LH 中表达囊泡 GABA 转运蛋白(VGAT;释放 GABA 的神经元的标记)的一群 VLPO 投射神经元。除了 VLPO 之外,这些神经元还投射到其他几个已建立的睡眠和唤醒节点,包括结节乳头核、腹侧导水管周围灰质和蓝斑。 LH VGAT+ 神经元的选择性和急性化学遗传学激活可显着促进觉醒,而急性抑制则可增加睡眠。由于其对 VLPO 的直接和大量输入,该群体可能在唤醒-睡眠切换中发挥特别重要的作用。
The largest synaptic input to the sleep-promoting ventrolateral preoptic area (VLPO) arises from the lateral hypothalamus, a brain area associated with arousal. However, the neurochemical identity of the majority of these VLPO-projecting neurons within the LH, as well as their function in the arousal network, remains unknown. Herein we describe a population of VLPO-projecting neurons in the LH that express the vesicular GABA transporter (VGAT; a marker for GABA-releasing neurons). In addition to the VLPO, these neurons also project to several other established sleep and arousal nodes, including the tuberomammillary nucleus, ventral periaqueductal gray and locus coeruleus. Selective and acute chemogenetic activation of LH VGAT+ neurons was profoundly wake-promoting whereas acute inhibition increased sleep. Because of its direct and massive inputs to the VLPO, this population may play a particularly important role in wake-sleep switching.
