采用扫描电镜和NiCl2轴突快速逆行扩散的方法研究了斑点龙脑后复合体。心肌体（CC）通过心肌神经I、II和III与大脑相连，并通过心脏连接器官相互连接。allata （CA）通过粗壮的corporis allati I （NCA I）与CC相连，并通过CC在CA鞘内的突起与后allatal神经（PAN）相连。在NCA I被切开后，将后脑复合体暴露在500 mM NiCl2中0.5分钟，导致CA/CC中具有轴突的神经元回填。在每个原大脑半球的脑间部（PI）和外侧部（PL）共观察到60个体体。回填PAN时，在PI中观察到20个体细胞，在每个PL中观察到5个体细胞。有可能，大脑两侧的PI和PL各有40个体体和20个体体向CA或更远处发送轴突。
The retrocerebral complex of D. punctata was studied by means of scanning electron microscopy and rapid retrograde axonal diffusion of NiCl2. The corpora cardiaca (CC) are joined to the brain via nervi corporis cardiaci I, II and III, and to each other via a cardiacal-commissure organ. Corpora allata (CA) are joined to the CC via stout nervi corporis allati I (NCA I) and to the post-allatal nerves (PAN) via projections of the CC within the CA sheath. Exposure of the retrocerebral complex, after the NCA I were sectioned, to 500 mM NiCl2 for 0.5 min resulted in the backfilling of neurons with axons in the CA/CC. A total of 60 somata were observed in the pars intercerebralis (PI) and 25 in the pars lateralis (PL) in each protocerebral hemisphere. When the PAN were backfilled, 20 somata in the PI and 5 in each PL were observed. It is possible that a total of 40 somata in the PI and 20 in the PL on each side of the brain send axons to the CA or beyond.
