배추흰나비 뇌의 신경망에서 신경세포의 축색과 축색사이에는 화학연접과 밀착연접이 형성되었고, 또한 간격연접이 형성되어 있는 경우도 관찰되었다. 축색과 신경교세포 사이에서는 밀착연접과 간격연접이 존재하였고 신경교세포와 신경교세포 사이에서는 흔히 간격연접이 관찰되었다.
In the neuropiles of the brains from the cabbage butterflies, Pieris rapae, the tight and gap junctions were electronmicroscopically investigated between adjacent axons, between adjacent axon and glial processes, and between adjacent glial processes. The axonal membranes were frequently found to form tight junctions, in addition to synaptic junctions. Infrequently the axonal membranes also form gap junctions with the adjacent axonal membranes. Sometimes the tight and gap junctions occur between the axon and glial process. The gap junctions were also found between the adjacent glial processes.
