Abstract

Subcortical ipsilateral afferents to mediodorsal (MD) thalamic nucleus were investigated by retrograde transport of horseradish peroxidase (HRP). HRP was injected into the rostral and caudal part of MD following both a vertical and an oblique stereotaxic approach. We have identified MD afferents from the following structures: area septalis, amygdaloid complex, hypothalamus, mamillary bodies, tuberculum olfactorium, claustrum, ventral tegmental area, zona incerta, substantia nigra, griseum centralis, formatio reticularis mesencephali and pontis oralis. The projections from hypothalamus, amygdaloid nuclei and area septalis and reticular formation are in agreement with the integrative function of sensory afferents of this thalamic nucleus.

摘要

采用辣根过氧化物酶（HRP）逆行运输法研究了丘脑内侧背核（MD）的皮质下同侧传入纤维。通过垂直和倾斜立体定向入路，将HRP注入MD的嘴侧和尾侧部分。我们已确定来自以下结构的MD传入纤维：隔区、杏仁复合体、下丘脑、乳头体、嗅结节、屏状核、腹侧被盖区、未定带、黑质、中央灰质、中脑网状结构和脑桥嘴侧网状结构。来自下丘脑、杏仁核、隔区和网状结构的投射与该丘脑核感觉传入的整合功能一致。
