Nociception in the cephalopod mollusc Octopus vulgaris: a contribution to mapping putative nociceptors in the octopus arm

I studied nociception in the cephalopod mollusc Octopus vulgaris by using a transcriptome-analysis, gene expression and immunohistochemistry with the aim of identifying putative nociceptors and possible pathways within the octopus arm. The analysis of the transcriptome allowed me also to identify a number of selected transcripts (> 30) and I evaluated predicted expression levels in silico in central and peripheral nervous system. My data, allow to identify fibres and cells suggested to be involved in nociceptive neural pathways for the first time in the arm of O. vulgaris.
