Shaping the future: the inhumanity of planetary calculation or how to live with digital uncertainty

Planetary computation. An epochal shift rewires humanity by impacting on our capacity to feel, to perceive, to sense and to think. Far from being a mere matter of speed of communication, this change has to do with the creation of new interlocking ecologies where information is sensed and the cognitive, perceptual and affective spheres mutate. Sensation prevails on signification. Data becomes us. Mediation shifts to immediation. This is the 4th Revolution when the digital-online world spills into and merges with the analogue-offline world. In this onlife experience, data is the new currency, code is synchronized to the human and the infosphere becomes synonymous with reality.1 The proliferation of smartalgorithmic environments evolving in real time, the colonization of daily life by social networks, the tsunami of data, the unstoppable googlification of knowledge together create new ecologies of cohabitation and coevolution of the human with the nonhumanity of planetary computation. Given this scenario, two questions emerge as urgent. What is the impact ofthe ongoing informatization of bodies, artefacts and environments on the whole of human cognition, affectivity and perceptual faculties? What kind of narratives, images and fictions are needed to make sense of the ecologies we now inhabit, populated by agents on a continuum between the human and the nonhuman, a mix of the human with machines, dataflows, codes, algorithms; strange entanglements of silicon and carbon

The Current State of Cephalopod Science and Perspectives on the Most Critical Challenges Ahead From Three Early-Career Researchers

International audienceHere, three researchers who have recently embarked on careers in cephalopod biology discuss the current state of the field and offer their hopes for the future. Seven major topics are explored genetics, aquaculture, climate change, welfare, behavior, cognition, and neurobiology. Recent developments in each of these fields are reviewed and the potential of emerging technologies to address specific gaps in knowledge about cephalopods are discussed. Throughout, the authors highlight specific challenges that merit particular focus in the near-term. This review and prospectus is also intended to suggest some concrete near-term goals to cephalopod researchers and inspire those working outside the field to consider the revelatory potential of these remarkable creatures

Case Studies in Invertebrate Visual Processing: I. Spectral and Spatial Processing in the Early Visual System of Drosophila melanogaster II. Binocular Stereopsis in Sepia officinalis

This thesis addresses two aspects of visual processing in two different invertebrate organisms. The fruit fly, Drosophila melanogaster, has emerged as a key model for invertebrate vision research. Despite extensive characterisation of motion vision, very little is known about how flies process colour information, or how the spectral content of light affects other visual modalities. With the aim to accurately dissect the different components of the Drosophila visual system responsible for processing colour, I have developed a versatile visual stimulation setup to probe for the combinations of spatial, temporal and spectral visual response properties. Using flies that express neural activity indicators, I can track visual responses to a colour stimulus (i.e. narrow bands of light across the spectrum) via a two-photon imaging system. The visual stimulus is projected on a specialised screen material that scatters wavelengths of light across the spectrum equally at all locations of the screen, thus enabling presentation of spatially structured stimuli. Using this setup, I have characterised spectral responses, intensity-response relationships, and receptive fields of neurons in the early visual system of a variety of genetically modified strains of Drosophila. Specifically, I compared visual responses in the medulla of flies expressing either a subset or all photoreceptor opsins, with differing levels of screening pigment present in the eye. I found layer-specific shifts of spectral response properties correlating with projection regions of photoreceptor terminals. I also 3 found that a reduction in screening pigment shifts the general spectral response in the neuropil towards the longer wavelengths of light. I have also mapped receptive fields across the different layers of the medulla for the peak spectral response wavelength. My results suggest that receptive field dimensions match the expected size predicted by the conservation of a columnar organisation in the medulla, with little variation from layer to layer. In a subset of these cells, we see an elongated receptive field suggestive of static orientation selectivity with an apparent split in the preferred axis of orientation of these receptive fields, with a near-orthogonal angle between the summed vectors of the split populations. The camera type eyes of vertebrates and cephalopods exhibit remarkable convergence, but it is currently unknown if the mechanisms for visual information processing in these brains, which exhibit wildly disparate architecture, is also shared. I chose to investigate the visual processing mechanism known as stereopsis in the cuttlefish Sepia officinalis. Stereoscopic vision is used to assess depth information by comparing the disparity between left and right visual fields. This strategy is commonplace in vertebrates having evolved multiple times independently but has only been demonstrated in one invertebrate: the praying mantis. Cuttlefish require precise distance estimation during their predatory hunt when they extend two tentacles in a ballistic strike to catch their target. Using a 3D perception paradigm whereby the cuttlefish were fitted with anaglyph glasses, I show that these animals use stereopsis to resolve distance to their prey. Although this is not an exclusive depth perception mechanism for hunting, it does shorten the time and distance covered prior to striking at a target. Furthermore, stereopsis in cuttlefish works differently to vertebrates, as cuttlefish can extract stereopsis cues from anti-correlated stimuli.BBSRC Doctoral Training Partnershi
