摘要

A polyclonal antiserum raised against crustacean cardioactive peptide labels 14 clusters of immunoreactive neurons in the protocerebrum of the spidersTegenaria atricaandNephila clavipes, and the harvestman (opilionid)Rilaena triangularis. In all species, these clusters possess the same number of neurons, and share similar structural and topological characteristics. Two sets of bilateral symmetrical neurons associated with the optic lobes and the arachnid “central body” were analysed in detail, comparing the harvestmanR. triangularisand the spidersBrachypelma albopilosa(Theraphosidae),Cupiennius salei(Lycosidae),Tegenaria atrica(Agelenidae),Meta segmentata(Metidae) andNephila clavipes(Araneidae). Sixteen neurons have been identified that display markedly similar axonal pathways and arborization patterns in all species. These neurons are considered homologues in the opilionid and the araneid brains. We presume that these putative phylogenetically persisting neurons represent part of the general morphological pattern of the arachmid br
