  1. The Meaning of Biological Signals.Marc Artiga, Jonathan Birch & Manolo Martínez - 2020 - Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 84:101348.
    We introduce the virtual special issue on content in signalling systems. The issue explores the uses and limits of ideas from evolutionary game theory and information theory for explaining the content of biological signals. We explain the basic idea of the Lewis-Skyrms sender-receiver framework, and we highlight three key themes of the issue: (i) the challenge of accounting for deception, misinformation and false content, (ii) the relevance of partial or total common interest to the evolution of meaningful signals, (...)

  2. Epigenetics Integrates Development, Signaling, Context, RNA-Networks and Evolution.Witzany Guenther - 2024 - In Guenther Witzany (ed.), Epigenetics in Biological Communication. Cham: SpringerNature. pp. 2-16.
    The metamorphosis from larvae to adult butterflies has represented the “mystery” of life since the ancient Greeks. How could we explain the various steps of development from caterpillars to the most beautiful butterflies? A mystery preva lent in the twentieth century concerned the storage of the complete genetic informa tion of an organism in the DNA of its every cell. How and why do so many different cell types develop throughout the lives of organisms at the right time and place? (...)

  3. Signals that make a Difference.Brett Calcott, Paul E. Griffiths & Arnaud Pocheville - 2017 - British Journal for the Philosophy of Science:axx022.
    Recent work by Brian Skyrms offers a very general way to think about how information flows and evolves in biological networks — from the way monkeys in a troop communicate, to the way cells in a body coordinate their actions. A central feature of his account is a way to formally measure the quantity of information contained in the signals in these networks. In this paper, we argue there is a tension between how Skyrms talks of signalling networks (...)

  4. Symbols, Signals, and the Archaeological Record.Kim Sterelny & Peter Hiscock - 2014 - Biological Theory 9 (1):1-3.
    The articles in this issue represent the pursuit of a new understanding of the human past, one that can replace the neo-saltationist view of a human revolution with models that can account for the complexities of the archaeological record and of human social lives. The articulation of archaeological, philosophical, and biological perspectives seems to offer a strong foundation for exploring available evidence, and this was the rationale for collecting these particular articles. Even at this preliminary stage there is a (...)

  5. An organisational approach to biological communication.Ramiro Frick, Leonardo Bich & Alvaro Moreno - 2019 - Acta Biotheoretica (2):103-128.
    This paper aims to provide a philosophical and theoretical account of biological communication grounded in the notion of organisation. The organisational approach characterises living systems as organised in such a way that they are capable to self-produce and self-maintain while in constant interaction with the environment. To apply this theoretical framework to the study of biological communication, we focus on a specific approach, based on the notion of influence, according to which communication takes place when a signal emitted (...)

  6. Pain signals are predominantly imperative.Manolo Martínez & Colin Klein - 2016 - Biology and Philosophy 31 (2):283-298.
    Recent work on signaling has mostly focused on communication between organisms. The Lewis–Skyrms framework should be equally applicable to intra-organismic signaling. We present a Lewis–Skyrms signaling-game model of painful signaling, and use it to argue that the content of pain is predominantly imperative. We address several objections to the account, concluding that our model gives a productive framework within which to consider internal signaling.

    Biosemiotics is a growing fi eld that investigates semiotic processes in the living realm in an attempt to combine the fi ndings of the biological sciences and semiotics. Semiotic processes are more or less what biologists have typically referred to as “ signals, ” “ codes, ”and “ information processing ”in biosystems, but these processes are here understood under the more general notion of semiosis, that is, the production, action, and interpretation of signs. Thus, biosemiotics can be seen as (...)

  9. Representation without Informative Signalling.Gerardo Alberto Viera - forthcoming - British Journal for the Philosophy of Science.
    Various writers have attempted to use the sender-receiver formalism to account for the representational capacities of biological systems. This paper has two goals. First, I argue that the sender-receiver approach to representation cannot be complete. The mammalian circadian system represents the time of day, yet it does not control circadian behaviours by producing signals with time of day content. Informative signalling need not be the basis of our most basic representational capacities. Second, I argue that representational capacities are (...)

    “Teleosemantic” or “biosemantic” theories form a strong naturalistic programme in the philosophy of mind and language. They seek to explain the nature of mind and language by recourse to a natural history of “proper functions” as selected-for effects of language- and thought-producing mechanisms. However, they remain vague with respect to the nature of the proposed analogy between selected-for effects on the biological level and phenomena that are not strictly biological, such as reproducible linguistic and cultural forms.

  11. Brain Function on the Basis of Biological Equilibrium - The Triggering Brain (2nd edition).Juergen Stueber - 2023 - Journal of Neurophilosophy 2023 (2(2)):432-452.
    A model of brain function is presented that is consistently based on the biological principle of equilibrium. The neuronal modules of the cerebral cortex are proposed as units in which equilibrium between incoming signals and the synaptic structure is determined or established. Because of the electromagnetic activity of the brain, the electromagnetic properties of thecells are brought into focus. Due to the synaptic changes of the modules -essentially during sleep -an electromagnetic resting balance between the modules is established. Incoming (...)

    Dance displays in gibbons: biological and linguistic perspectives on structured, intentional, and rhythmic body movement.Camille Coye, Kai Caspar & Pritty Patel-Grosz - 2024 - Primates.
    Female crested gibbons (genus Nomascus) perform conspicuous sequences of twitching movements involving the rump and extremities. However, these dances have attracted little scientific attention and their structure and meaning remain largely obscure. Here we analyse close-range video recordings of captive crested gibbons, extracting descriptions of dance in four species (N. annamensis, N. gabriellae, N. leucogenys and N. siki). In addition, we report results from a survey amongst relevant professionals clarifying behavioural contexts of dance in captive and wild crested gibbons. Our (...)

    Note: Many types of nanosensors are designed using CP nanomaterials for nanobiological applications. (Conductive surface) The oxidation of conductive polymeric materials is easily altered by redox mechanisms, and the charge transfer properties of these materials are affected by structural parameters, such as diameter and dimensions.

  14. Control Mechanisms: Explaining the Integration and Versatility of Biological Organisms.Leonardo Bich & William Bechtel - 2022 - Adaptive Behavior.
    Living organisms act as integrated wholes to maintain themselves. Individual actions can each be explained by characterizing the mechanisms that perform the activity. But these alone do not explain how various activities are coordinated and performed versatilely. We argue that this depends on a specific type of mechanism, a control mechanism. We develop an account of control by examining several extensively studied control mechanisms operative in the bacterium E. coli. On our analysis, what distinguishes a control mechanism from other mechanisms (...)

    Many believe that a suitably programmed computer could act for its own goals and experience feelings. I challenge this view and argue that agency, mental causation and qualia are all founded in the unique, homeostatic nature of living matter. The theory was formulated for coherence with the concept of an agent, neuroscientific data and laws of physics. By this method, I infer that a successful action is homeostatic for its agent and can be caused by a feeling - which does (...)

    THE INTUITION OF KNOWING: ITS BIOLOGICAL FUNCTION AND NATURAL TRIGGERING-CONDITIONS.Nathan J. Fox - 2017 - Dissertation, Open University (Uk)
    Over the last hundred years, competing and incompatible positions in relation to basic problems of knowledge and the use of the verb ‘to know’ have multiplied; and the prospect of a consensus solution emerging with respect to any of the problems has not seemed particularly good. We have a Gordian knot. Even so, I suggest that we also have a way to cut it. This will involve identifying why the cognitive mechanism that produces our intuitions of knowing evolved and was (...)

    Living organisms are exposed to numerous influencing factors. This holds also true for their infrastructures that are processing and transducing information like endocrine networks or nerval channels. Therefore, the ability to compensate for noise is crucial for survival. An efficient mechanism to neutralise disturbances is instantiated in form of parallel complementary communication channels exerting antagonistic effects at their common receivers. Different signal processing types share the ability to suppress noise, to widen the system’s regulation capacity, and to provide for variable (...)

    This paper advances the development of a phylogeny-based psychology in which cognitive ability types are individuated as characters in the evolutionary biological sense. I explain the character concept and its utility in addressing (or dissolving) conceptual problems arising from discoveries of cognitive abilities across a wide range of species. I use the examples of stereopsis in the praying mantis, internal cell-to-cell signaling in plants, and episodic memory in scrub jays to show how anthropocentric cognitive ability types can be reformulated (...)

    Deception has recently received a significant amount of attention. One of main reasons is that it lies at the intersection of various areas of research, such as the evolution of cooperation, animal communication, ethics or epistemology. This essay focuses on the biological approach to deception and argues that standard definitions put forward by most biologists and philosophers are inadequate. We provide a functional account of deception which solves the problems of extant accounts in virtue of two characteristics: deceptive states (...)

  23. Formation and meaning of mental symptoms: history and epistemology Lecture presented at the Roman Circle of Psychopathology, Rome, Italy, 16th February 2012.German Elias Berrios - 2013 - Dialogues in Philosophy, Mental and Neuro Sciences 6 (2):39-48.
    Historical evidence shows that mental symptoms were constructed in a particular historical and cultural context (19th Century alienism). According to the Cambridge model of symptom-formation, mental symptoms are mental acts whereby sufferers configure, by means of cultural templates, information invading their awareness. This information, which can be of biological or semantic origin, is pre-conceptual and pre-linguistic and to be understood and communicated requires formatting and linguistic collocation. Mental symptoms are hybrid objects, that is, blends of inchoate biological or (...)

  25. Using neurons to maintain autonomy: Learning from C. elegans.William Bechtel & Leonardo Bich - 2023 - Biosystems 232:105017.
    Understanding how biological organisms are autonomous—maintain themselves far from equilibrium through their own activities—requires understanding how they regulate those activities. In multicellular animals, such control can be exercised either via endocrine signaling through the vasculature or via neurons. In C. elegans this control is exercised by a well-delineated relatively small but distributed nervous system that relies on both chemical and electric transmission of signals. This system provides resources to integrate information from multiple sources as needed to maintain the organism. (...)

  26. How to Be a Realist About Sui Generis Teleology Yet Feel at Home in the 21St Century.Richard Cameron - 2004 - The Monist 87 (1):72-95.
    Contemporary discussion of biological teleology has been dominated by a complacent orthodoxy. Responsibility for this shortcoming rests primarily, I think, with those who ought to have been challenging dogma but have remained silent, leaving the orthodox to grow soft, if happily. In this silence, champions of orthodoxy have declared a signal victory, proclaiming the dominance of their view as one of philosophy’s historic successes. But this declaration is premature at best—this would be neither the first nor probably the last (...)

Wiener's control theory in the following three ways: (1) It combined control theory with theoretical biology, considered control mechanisms as the essence of life, and proposed a more complete model of control of life. (2) It developed the concept of purposiveness in control systems, created the scientific concept of baseline signal or baseline information, and established the purposive formulation of cybernetics.

  28. Coral bleaching to starvation: Impending mass mortality and feasibility of sustainable conservation strategies.Minh-Hoang Nguyen & Quan-Hoang Vuong - manuscript
    Coral reefs provide substantial benefits to humans by generating biologically diverse ecosystems and reducing coastal hazards. However, in recent years, mass mortality of coral reefs due to bleaching has been witnessed in the ocean worldwide. Bleaching induced by the loss of the symbiotic relationship between algae and coral is mainly attributed to climate change. Marine protected areas (MPAs) can effectively prevent local disturbances but are less likely to conserve the coral reefs from global events like climate change. Other conservation and (...)

    Organization figures centrally in the understanding of biological systems advanced by both new mechanists and proponents of the autonomy framework. The new mechanists focus on how components of mechanisms are organized to produce a phenomenon and emphasize productive continuity between these components. The autonomy framework focuses on how the components of a biological system are organized in such a way that they contribute to the maintenance of the organisms that produce them.

    Curiosity is evident in humans of all sorts from early infancy, and it has also been said to appear in a wide range of other animals, including monkeys, birds, rats, and octopuses.

Even if rats must learn many things to survive, one might expect their learning must be driven (...)

  31. Altruistic Deception.Jonathan Birch - 2019 - Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 74:27-33.
    Altruistic deception (or the telling of “white lies”) is common in humans. Does it also exist in non-human animals? On some definitions of deception, altruistic deception is impossible by definition, whereas others make it too easy by counting useful-but-ambiguous information as deceptive. I argue for a definition that makes altruistic deception possible in principle without trivializing it. On my proposal, deception requires the strategic exploitation of a receiver by a sender, where “exploitation” implies that the sender elicits a behaviour in (...)

    Located within the ascending reticular activating system are nuclei which release neurotransmitters such as acetylcholine, serotonin, dopamine, and norepinephrine. These nuclei have widespread projections that extend into the limbic system and throughout cortex. Activation of these neurotransmitters during awake states leads to arousal, while inhibition leads to the loss of consciousness experienced during slow-wave sleep. Previously, we proposed a mechanism in which cardiorespiratory synchronization may underlie the widespread hyperpolarization that occurs throughout the brain during slow-wave sleep. We further propose that (...)

    Following the pioneering studies of the receptive field (RF), the concept gained further significance for visual perception by the discovery of input effects from beyond the classical RF. These studies demonstrated that neuronal responses could be modulated by stimuli outside their RFs, consistent with the perception of induced brightness, color, orientation, and motion. Lesion scotomata are similarly modulated perceptually from the surround by RFs that have migrated from the interior to the outer edge of the scotoma and in this way (...)

    Bacteria do many things as organized populations. We have recently learned much about the molecular basis of intercellular communication among prokaryotes. Colonies display bacterial capacities for multicellular coordination which can be useful in nature where bacteria predominantly grow as films, chains, mats and colonies. E. coli colonies are organized into differentiated non-clonal populations and undergo complex morphogenesis. Multicellularity regulates many aspects of bacterial physiology, including DNA rearrangement systems. In some bacterial species, colony development involves swarming (active migration of cell groups). (...)

    This paper investigates how global coherence is represented in consciousness. It summarizes various lines of research that I have developed over the last twenty years, employing a method that intersects phenomenological with bio-functional analysis. The phenomenological analysis derives from William James's treatment of the fringe, especially a component feeling he called 'right direction'and I call 'rightness'. My bio-functional analysis centres on the limitations of consciousness, and the design strategies that have evolved to finesse these limitations. I argue that fringe phenomenology, (...)

    According to some critics, if biology is a kind of reverse engineering for the nature, it is quite poorly prepared for the task. Thus, the issue is more likely with its ontology. Multiple hypotheses and conjectures found in papers on methodological issues claim that living systems should be viewed as complex networks of signal-transmitting paths, both neural and non-neural, that feature modularity and feedback circuits and are prone to emergent properties and increasing complexity. If so, we are on the eve (...)

  42. Evolutionary Scenario linking the Nature of Self-Consciousness to Anxiety Management (Dec 2017).Christophe Menant - manuscript
    Anxiety is a main contributor to human psychological sufferings. Its evolutionary sources are generally related to alert signals for coping with adverse or unexpected situations [Steiner, 2002] or to hunter-gatherer emotions mismatched with today environments [Horwitz & Wakefield, 2012]. We propose here another evolutionary perspective that links human anxiety to an evolutionary nature of self-consciousness. That approach introduces new relations between mental health and human mind. The proposed evolutionary scenario starts with the performance of primate identification with conspecifics [de Waal (...)

    FISIOLOGIA DO CICLO ESTRAL DOS ANIMAIS -/- Departamento de Zootecnia – UFRPE Embrapa Semiárido e IPA -/- • _____OBJETIVO -/- O cio ou estro é a fase reprodutiva dos animais, onde as fêmeas apresentam receptividade sexual seguida de ovulação. Para tanto, é necessário entender a fisiologia do estro para a realização do manejo reprodutivo dos animais. Em geral, as fêmeas manifestam comportamentos fora do comum quando estão ciclando, tais comportamentos devem ser observados para que não percam o pico de ovulação (...)

  45. Methods and Applications of Non-Linear Analysis in Neurology and Psycho-physiology.Elio Conte - 2012 - Journal of Consciousness Exploration and Research 1 (9):1070-1138.
    In the light of the results obtained during the last two decades in analysis of signals by time series, it has become evident that the tools of non linear dynamics have their elective role of application in biological, and, in particular, in neuro-physiological and psycho-physiological studies. The basic concept in non linear analysis of experimental time series is that one of recurrence whose conceptual counterpart is represented from variedness and variability that are the foundations of complexity in dynamic processes.

  47. Virtue Signaling and Moral Progress.Evan Westra - 2021 - Philosophy and Public Affairs 49 (2):156-178.
    ‘Virtue signaling’ is the practice of using moral talk in order to enhance one’s moral reputation. Many find this kind of behavior irritating. However, some philosophers have gone further, arguing that virtue signaling actively undermines the proper functioning of public moral discourse and impedes moral progress. Against this view, I argue that widespread virtue signaling is not a social ill, and that it can actually serve as an invaluable instrument for moral change, especially in cases where moral argument alone does (...)

  48. Signaling without cooperation.Marc Artiga - 2014 - Biology and Philosophy 29 (3):357-378.
    Ethological theories usually attribute semantic content to animal signals. To account for this fact, many biologists and philosophers appeal to some version of teleosemantics. However, this picture has recently came under attack: while mainstream teleosemantics assumes that representational systems must cooperate, some biologists and philosophers argue that in certain cases signaling can evolve within systems lacking common interest. In this paper I defend the standard view from this objection.

  49. Models, information and meaning.Marc Artiga - 2020 - Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 82:101284.
    There has recently been an explosion of formal models of signalling, which have been developed to learn about different aspects of meaning. This paper discusses whether that success can also be used to provide an original naturalistic theory of meaning in terms of information or some related notion. In particular, it argues that, although these models can teach us a lot about different aspects of content, at the moment they fail to support the idea that meaning just is some (...)

  50. How to do things with nonwords: pragmatics, biosemantics, and origins of language in animal communication.Dorit Bar-On - 2021 - Biology and Philosophy 36 (6):1-25.
    Recent discussions of animal communication and the evolution of language have advocated adopting a ‘pragmatics-first’ approach, according to which “a more productive framework” for primate communication research should be “pragmatics, the field of linguistics that examines the role of context in shaping the meaning of linguistic utterances”. After distinguishing two different conceptions of pragmatics that advocates of the pragmatics-first approach have implicitly relied on, I argue that neither conception adequately serves the purposes of pragmatics-first approaches to the origins of human (...)
