    Anticipatory Functions, Digital-Analog Forms and Biosemiotics: Integrating the Tools to Model Information and Normativity in Autonomous Biological Agents.Argyris Arnellos, Luis Emilio Bruni, Charbel Niño El-Hani & John Collier - 2012 - Biosemiotics 5 (3):331-367.
    We argue that living systems process information such that functionality emerges in them on a continuous basis. We then provide a framework that can explain and model the normativity of biological functionality. In addition we offer an explanation of the anticipatory nature of functionality within our overall approach. We adopt a Peircean approach to Biosemiotics, and a dynamical approach to Digital-Analog relations and to the interplay between different levels of functionality in autonomous systems, taking an integrative approach. We then apply (...)

    Hierarchical Categorical Perception in Sensing and Cognitive Processes.Luis Emilio Bruni - 2008 - Biosemiotics 1 (1):113-130.
    This article considers categorical perception (CP) as a crucial process involved in all sort of communication throughout the biological hierarchy, i.e. in all of biosemiosis. Until now, there has been consideration of CP exclusively within the functional cycle of perception–cognition–action and it has not been considered the possibility to extend this kind of phenomena to the mere physiological level. To generalise the notion of CP in this sense, I have proposed to distinguish between categorical perception (CP) and categorical sensing (CS) (...)

    Multi-Level Semiosis: A Paradigm of Emergent Innovation.Luis Emilio Bruni & Franco Giorgi - 2016 - Biosemiotics 9 (3):307-318.
    In this introductory article to the special issue on Multi-level semiosis we attempt to stage the background for qualifying the notion of “multi-levelness” when considering communication processes and semiosis in all life forms, i.e. from the cellular to the organismic level. While structures are organized hierarchically, communication processes require a kind of processual organization that may be better described as being heterarchical. Theoretically, the challenge arises in the temporal domain, that is, in the developmental and evolutionary dimension of dynamic semiotic (...)

    Receptor Oligomerization as a Process Modulating Cellular Semiotics.Franco Giorgi, Luis Emilio Bruni & Roberto Maggio - 2010 - Biosemiotics 3 (2):157-176.
    The majority of G protein-coupled receptors (GPCRs) self-assemble in the form dimeric/oligomeric complexes along the plasma membrane. Due to the molecular interactions they participate, GPCRs can potentially provide the framework for discriminating a wide variety of intercellular signals, as based on some kind of combinatorial receptor codes. GPCRs can in fact transduce signals from the external milieu by modifying the activity of such intracellular proteins as adenylyl cyclases, phospholipases and ion channels via interactions with specific G-proteins. However, in spite of (...)

    Does “Quorum Sensing” Imply a New Type of Biological Information?Luis Emilio Bruni - 2002 - Sign Systems Studies 30 (1):221-242.
    When dealing with biological communication and information, unifying concepts are necessary in order to couple the different “codes” that are being inductively “cracked” and defined at different emergent and “deemergent” levels of the biological hierarchy. In this paper I compare the type of biological information implied by genetic information with that implied in the concept of “quorum sensing” (which refers to a prokaryotic cell-to-cell communication system) in order to explore if such integration is being achieved. I use the Lux operon (...)

    Semiotic Selection of Mutated or Misfolded Receptor Proteins.Franco Giorgi, Luis Emilio Bruni & Roberto Maggio - 2013 - Biosemiotics 6 (2):177-190.
    Receptor oligomerization plays a key role in maintaining genome stability and restricting protein mutagenesis. When properly folded, protein monomers assemble as oligomeric receptors and interact with environmental ligands. In a gene-centered view, the ligand specificity expressed by these receptors is assumed to be causally predetermined by the cell genome. However, this mechanism does not fully explain how differentiated cells have come to express specific receptor repertoires and which combinatorial codes have been explored to activate their associated signaling pathways. It is (...)

    Biosemiotics and Ecological Monitoring.Luis Emilio Bruni - 2001 - Sign Systems Studies 29 (1):293-311.
    During the recent decades, a global culrural-institutional network has gradually grown lip to project, implement, and use an enormous technological web that is supposed to observe, monitor, communicate, inventory, and assess our environment and its biodiversity in order to implement sustainable management models. The majority of "knowledge tools" that have been incorporated in the mainstream of this "techno-web" are amply based on a combination of mechanistic biology, genetic reductionism, economical determinism and neo-Darwinian cultural and biological perspectives. These approaches leave aside (...)

    Germ Cells Are Made Semiotically Competent During Evolution.Franco Giorgi & Luis Emilio Bruni - 2016 - Biosemiotics 9 (1):31-49.
    Germ cells are cross-roads of development and evolution. They define the origin of every new generation and, at the same time, represent the biological end-product of any mature organism. Germ cells are endowed with the following capacities: to store a self-descriptive program, to accumulate a protein-synthesizing machinery, and to incorporate enough nourishment to sustain embryonic development. To accomplish this goal, germ cells do not simply unfold a pre-determined program or realize a sole instructive role. On the contrary, due to the (...)

    The Egg as a Semiotic Gateway to Reproduction.Franco Giorgi, Luis Emilio Bruni & Louis J. Goldberg - 2013 - Biosemiotics 6 (3):489-496.
    The egg behaves as a prospective cell sustaining the developmental processes of the future embryo. In biosemiotic terms, this apparent teleonomic behaviour can be accounted for without referring to the exclusive causal role played by its genetic makeup. We envision two different processes that are uniquely found in the oocyte: (1) the first involves the mechanisms by which large amounts of mRNA accumulate in the ooplasm to establish the embryo axes prior to fertilization; (2) the second involves transfer of an (...)

    On the Embedded Cognition of Non-Verbal Narratives.Luis Emilio Bruni & Sarune Baceviciute - 2014 - Sign Systems Studies 42 (2-3):359.
    Acknowledging that narratives are an important resource in human communication and cognition, the focus of this article is on the cognitive aspects ofinvolvement with visual and auditory non-verbal narratives, particularly in relation to the newest immersive media and digital interactive representational technologies. We consider three relevant trends in narrative studies that have emerged in the 60 years of cognitive and digital revolution. The issue at hand could have implications for developmental psychology, pedagogics, cognitive science, cognitive psychology, ethology and evolutionary studies (...)
