Abstract

The projections of the pedunculopontine tegmental nucleus (PPT) were studied in the rat using anterograde and retrograde transport methods. Ascending fibers to the substantia nigra, the subthalamic nucleus, the globus pallidus, the entopeduncular nucleus, the neostriatum, the ventral thalamus, and the medial and sulcal frontal cortical areas were identified. PPT has been reported to receive afferents from the substantia nigra, the subthalamic nucleus, the entopeduncular nucleus and the neostriatum. The connections of PPT provide an additional limb to extrapyramidal circuitry.

摘要

运用顺行和逆行示踪法，对大鼠脚桥被盖核（PPT）的投射进行了研究。确定了向黑质、丘脑底核、苍白球、脚内核、新纹状体、腹侧丘脑以及额叶内侧和中央沟皮质区域的上行纤维。据报道，PPT接受来自黑质、丘脑底核、脚内核和新纹状体的传入纤维。PPT的连接为锥体外系回路增添了一个分支。
