Abstract:
The location of AChE in the brains of Polyrhachis vicina Roger by histochemistry is reported. The results exhibit that the distribution of AChE are widespread. They mainly locate in the deuterencephalon, ganglion subpharyngeale, deutocerebrum, then the medial complex, calyxes of mushroom body, optic lobes, the pedicels, and less in lobes of mushroom body. The comparision of AChE positive reaction in different grades of Polyrhachis vicina Roger display that there are fewer positive reaction of AChE in the optic lobes and olfactory lobes of worker than male′s and female′s, the distribution of AChE in the medial complex of female has stronger reaction than other′s. These results indicate that cholinergic nerves join in the transmission of olfactory sensation and olfactory sensation information in the brain of Polyrhachis vicina Roger;Acording to the clinical diagnosis criteria,the calyxes of mushroom bodies belong to the input regions of sensory information, the pedunculus and lobes are the output regions of the mushroom bodies′s feedback message.
