Project description:Coleoid cephalopods possess a highly complex nervous system and a rich behavioral repertoire that is unique within the invertebrates and is comparable to – but evolved independently from – the vertebrates (Shigeno et al. 2018). To explain this complexity, previous studies have implicated a unusually high level of mRNA editing in transcripts expressed in both the octopus and squid nervous system (Albertin et al. 2015; Alon et al. 2015; Liscovitch-Brauer et al. 2017). We have sequenced RNA across 18 tissues from the octopus O. vulgaris, and analyzed the extent of mRNA isoform usage as well as the expression of microRNAs in the nervous system in comparison to non-neuronal tissues.

Project description:Cephalopods have a remarkable visual system, with a camera-type eye, high acuity vision, and a wide range of sophisticated visual behaviors. However, the cephalopod brain is organized dramatically differently from that of vertebrates, as well as other invertebrates, and little is known regarding the cell types and molecular determinants of their visual system organization beyond neuroanatomical descriptions. Here we present a comprehensive single-cell molecular atlas of the octopus optic lobe, which is the primary visual processing structure in the cephalopod brain. We combined single-cell RNA sequencing with RNA fluorescence in situ hybridization to both identify putative molecular cell types and determine their anatomical and spatial organization within the optic lobe. Our results reveal six major neuronal cell classes identified by neurotransmitter/neuropeptide usage, in addition to non-neuronal and immature neuronal populations. Moreover, we find that additional markers divide these neuronal classes into subtypes with distinct anatomical localizations, revealing cell type diversity and a detailed laminar organization within the optic lobe. We also delineate the immature neurons within this continuously growing tissue into subtypes defined by evolutionarily conserved fate specification genes as well as novel cephalopod- and octopus- specific genes. Together, these findings outline the organizational logic of the octopus visual system, based on functional determinants, laminar identity, and developmental markers/pathways. The resulting atlas presented here delineates the “parts list” of the neural circuits used for vision in octopus, providing a platform for investigations into the development and function of the octopus visual system as well as the evolution of visual processing.
