摘要
本文应用荧光素双标法,研究了大鼠中脑中央灰质和中缝背核向伏核和中缝大核的分支投射。将双苯甲亚胺(Bb)和碘化丙啶(PI)分别定向注入中缝大核和一侧伏核。在中脑中央灰质和中缝背核内见到双标细胞和两种单标细胞。双标细胞占3种标记细胞总数的21％,PI单标细胞占32％,Bb单标细胞占47％。标记细胞多位于注射侧中脑中央灰质中段、尾段的腹外侧区、内侧区腹侧部及中缝背核内,以中型梭形和三角形细胞为主。
In order to study the bifurcate projections of midbrain periaqueductal gray and nucleus raphe dorsalis to nucleus accumbens and nucleus raphe magnus, the fluorescence double-labeled method was used in the present study. Bisbenzimide (Bb) and propidium iodide (PI) were injected into nucleus raphe magnus and unilateral nucleus accumbens stereotaxically according to the time period necessary for their axonal transport. The percentages of double-labeled neurons were 21％; PI single labeled neurons were 32％; Bb single labeled neurons were 47％. Most of the labeled neurons were located in the middle and caudal parts of periaqueductal gray and the nucleus raphe dorsalis, and most were medium sized and fusiform and triangular in shape.
