    Let the Little Children Come - Newborns Contain Intuitive Version of Physics' Unified Theory.Bartlett Rodney - 2017 - Vixra.Org (Free Forums).
    In his book "A Brief History of Time", Stephen Hawking says "If a complete unified theory was discovered, it would only be a matter of time before it was digested and simplified - and taught in schools, at least in outline. We should then all be able to have some understanding of the laws that govern the universe and are responsible for our existence." If complete, a unified theory would be physical and embrace all the space, matter and time of (...)

  2. Embraining Culture: Leaky Minds and Spongy Brains.Julian Kiverstein & Mirko Farina - 2011 - Teorema: International Journal of Philosophy (2).
    We offer an argument for the extended mind based on considerations from brain development. We argue that our brains develop to function in partnership with cognitive resources located in our external environments. Through our cultural upbringing we are trained to use artefacts in problem solving that become factored into the cognitive routines our brains support. Our brains literally grow to work in close partnership with resources we regularly and reliably interact with. We take this argument to be in line with (...)

  3. Sleep and Dreaming in the Predictive Processing Framework.Alessio Bucci & Matteo Grasso - 2017 - Philosophy and Predictive Processing.
    Sleep and dreaming are important daily phenomena that are receiving growing attention from both the scientific and the philosophical communities. The increasingly popular predictive brain framework within cognitive science aims to give a full account of all aspects of cognition. The aim of this paper is to critically assess the theoretical advantages of Predictive Processing (PP, as proposed by Clark 2013, Clark 2016; and Hohwy 2013) in defining sleep and dreaming. After a brief introduction, we overview the state of the (...)

  4. Free Energy and Virtual Reality in Psychoanalysis and Neuroscience: A Complexity Theory of Dreaming and Mental Disorder.Jim Hopkins - 2016 - Frontiers in Psychology 7.
    This paper compares the free energy neuroscience now advocated by Karl Friston and his colleagues with that hypothesised by Freud, arguing that Freud's notions of conflict and trauma can be understood in terms of computational complexity. It relates Hobson and Friston's work on dreaming and the reduction of complexity to contemporary accounts of dreaming and the consolidation of memory, and advances the hypothesis that mental disorder can be understood in terms of computational complexity and the mechanisms, including synaptic (...), that have evolved to reduce it.

  5. Exempting All Minimal-Risk Research From IRB Review: Pruning or Poisoning the Regulatory Tree?Mahesh Ananth & Mike Scheessele - 2012 - IRB: Ethics & Human Research 34 (2):9-14.
    In a recent commentary, Kim and colleagues argued that minimal-risk research should be deregulated so that such studies do not require review by an institutional review board. They claim that regulation of minimal-risk studies provides no adequate counterbalancing good and instead leads to a costly human subjects oversight system. We argue that the counterbalancing good of regulating minimal-risk studies is that oversight exists to ensure that respect for persons and justice requirements are satisfied when they otherwise might not be.

  7. Preliminary Considerations on a Possible Quantum Model of Consciousness Interfaced with a Non Lipschitz Chaotic Dynamics of Neural Activity.Elio Conte - 2012 - Journal of Consciousness Exploration and Research 3 (10):905-921.
    A model of consciousness and conscious experience is introduced. Starting with a non-Lipschitz Chaotic dynamics of neural activity, we propose that the synaptic transmission between adjacent as well as distant neurons should be regulated in brain dynamics through quantum tunneling. Further, based on various studies of different previous authors, we consider the emergence of very large quantum mechanical system representable by an abstract quantum net entirely based on quantum-like entities having in particular the important feature of expressing self-reference similar (...)

    Long-Term Potentiation: One Kind or Many?Jacqueline Sullivan - 2017 - In Marcus P. Adams, Zvi Biener, Uljana Feest & Jacqueline Anne Sullivan (eds.), Eppur Si Muove: Doing History and Philosophy of Science with Peter Machamer: A Collection of Essays in Honor of Peter Machamer. Springer.
    Do neurobiologists aim to discover natural kinds? I address this question in this chapter via a critical analysis of classification practices operative across the 43-year history of research on long-term potentiation. I suggest that this 43-year history supports the idea that the structure of scientific practice surrounding LTP research has remained an obstacle to the discovery of natural kinds as philosophers of science have traditionally conceived them.

  9. How to Be a Spacetime Substantivalist.Trevor Teitel - 2022 - Journal of Philosophy 119 (5):233-278.
    The consensus among spacetime substantivalists is to respond to Leibniz's classic shift arguments, and their contemporary incarnation in the form of the hole argument, by pruning the allegedly problematic metaphysical possibilities that generate these arguments. Some substantivalists do so by directly appealing to a modal doctrine akin to anti-haecceitism. Other substantivalists do so by appealing to an underlying hyperintensional doctrine that implies some such modal doctrine. My first aim in this paper is to pose a challenge for all extant (...)

  10. Bridging Emotion Theory and Neurobiology Through Dynamic Systems Modeling.Marc D. Lewis - 2005 - Behavioral and Brain Sciences 28 (2):169-194.
    Efforts to bridge emotion theory with neurobiology can be facilitated by dynamic systems (DS) modeling. DS principles stipulate higher-order wholes emerging from lower-order constituents through bidirectional causal processes cognition relations. I then present a psychological model based on this reconceptualization, identifying trigger, self-amplification, and self-stabilization phases of emotion-appraisal states, leading to consolidating traits. The article goes on to describe neural structures and functions involved in appraisal and emotion, as well as DS mechanisms of integration by which they interact. These mechanisms (...)

  11. Buddhist Enlightenment and the Destruction of Attractor Networks: A Neuroscientific Speculation on the Buddhist Path From Everyday Consciousness to Buddha-Awakening.Patricia Sharp - 2011 - Journal of Consciousness Studies 18 (3-4):3-4.
    Buddhist philosophy asserts that human suffering is caused by ignorance regarding the true nature of reality. According to this, perceptions and thoughts are largely fabrications of our own minds, based on conditioned tendencies which often involve problematic fears, aversions, compulsions, etc. In Buddhist psychology, these tendencies reside in a portion of mind known as Store consciousness. Here, I suggest a correspondence between this Buddhist Store consciousness and the neuroscientific idea of stored synaptic weights. These weights are strong synaptic (...)

  12. Quantum Propensities in the Brain Cortex and Free Will.Danko D. Georgiev - 2021 - Biosystems 208:104474.
    Capacity of conscious agents to perform genuine choices among future alternatives is a prerequisite for moral responsibility. Determinism that pervades classical physics, however, forbids free will, undermines the foundations of ethics, and precludes meaningful quantification of personal biases. To resolve that impasse, we utilize the characteristic indeterminism of quantum physics and derive a quantitative measure for the amount of free will manifested by the brain cortical network. The interaction between the central nervous system and the surrounding environment is shown to (...)

  13. Medical Models of Addiction.Harold Kincaid & Jacqueline Anne Sullivan - 2010 - In Kincaid Ross (ed.), What is Addiction?
    Biomedical science has been remarkably successful in explaining illness by categorizing diseases and then by identifying localizable lesions such as a virus and neoplasm in the body that cause those diseases. Not surprisingly, researchers have aspired to apply this powerful paradigm to addiction. So, for example, in a review of the neuroscience of addiction literature, Hyman and Malenka (2001, p. 695) acknowledge a general consensus among addiction researchers that “[a]ddiction can appropriately be considered as a chronic medical illness.” Like other (...)

  14. Informational Mode of the Brain Operation and Consciousness as an Informational Related System.Florin Gaiseanu - 2019 - Archives in Biomedical Engineering and Biotechnology 1 (5):1-7.
    Introduction: the objective of the investigation is to analyse the informational operating-mode of the brain and to extract conclusions on the structure of the informational system of the human body and consciousness. Analysis: the mechanisms and processes of the transmission of information in the body both by electrical and non-electrical ways are analysed in order to unify the informational concepts and to identify the specific essential requirements supporting the life. It is shown that the electrical transmission can be described by (...)

    Real Attribute Learning Algorithm.Julio Michael Stern, Marcelo de Souza Lauretto, Fabio Nakano & Celma de Oliveira Ribeiro - 1998 - ISAS-SCI’98 2:315-321.
    This paper presents REAL, a Real-Valued Attribute Classification Tree Learning Algorithm. Several of the algorithm's unique features are explained by úe users' demands for a decision support tool to be used for evaluating financial operations strategies. Compared to competing algorithms, in our applications, REAL presents maj or advantages : (1) The REAL classification trees usually have smaller error rates. (2) A single conviction (or trust) measure at each leaf is more convenient than the traditional (probability, confidence-level) pair. (3) No need (...)

    From Biological Synapses to "Intelligent" Robots.Birgitta Dresp-Langley - 2022 - Electronics 11:1-28.
    This selective review explores biologically inspired learning as a model for intelligent robot control and sensing technology on the basis of specific examples. Hebbian synaptic learning is discussed as a functionally relevant model for machine learning and intelligence, as explained on the basis of examples from the highly plastic biological neural networks of invertebrates and vertebrates. Its potential for adaptive learning and control without supervision, the generation of functional complexity, and control architectures based on self-organization is brought forward. Learning (...)

  17. Bergson, Complexity and Creative Emergence.David Kreps - 2014 - Palgrave-Macmillan.
    This is a book about evolution from a post-Darwinian perspective. It recounts the core ideas of French philosopher Henri Bergson and his rediscovery and legacy in the poststructuralist critical philosophies of the 1960s, and explores the confluences of these ideas with those of complexity theory in environmental biology. The failings in the development of systems theory, many of which complex systems theory overcomes, are retold; with Bergson, this book proposes, some of the rest may be overcome too. It asserts that (...)

    Three Philosophical Problems About Consciousness.Nicholas Maxwell - 2002 - Ethical Record 107 (4):3-11.
    I am inclined to think that there are three basic philosophical problems that arise in connection with consciousness. (1) Existence. Why does sentience or consciousness exist at all? Why are we not zombies? (2) Intelligibility. Granted that consciousness exists, what is it? How is it to be explained and understood? On the face of it, there could be no greater mystery than that brains should somehow produce, or be, our states of awareness, our thoughts, feelings, perceptions and desires. What is (...)

  19. Self-Knowledge, Transformation and Redemption (Ch.9 in "Our Other Mind").Barry Klein - manuscript
    This process is the transformation of the self, even to the extent that we no longer recognize ourselves although, oddly, something in us will then recognize our ‘new’ self as being what we really are, or at least what we started out to be. Then, in a way, we are like the seedling of some wonderful tree which has been overtaken by a parasitic plant until very little of the original tree is recognizable – it may have become dwarfed, hollowed (...)

  20. Framework of Consciousness From Semblance of Activity at Functionally LINKed Postsynaptic Membranes.Kunjumon Vadakkan - 2010 - Frontiers in Consciousness Research 1 (1):1-12.
    Consciousness is seen as a difficult “binding” problem. Binding, a process where different sensations evoked by an item are associated in the nervous system, can be viewed as a process similar to associative learning. Several reports that consciousness is associated with some form of memory imply that different forms of memories have a common feature contributing to consciousness. Based on a proposed synaptic mechanism capable of explaining different forms of memory, we developed a framework for consciousness. It is based (...)

  21. Morphing Intelligence: From IQ Measurement to Artificial Brains. [REVIEW]Ekin Erkan - 2020 - Chiasma 6 (1):248-260.
    In her seminal text, What Should We Do With Our Brain? (2008), Catherine Malabou gestured towards neuroplasticity to upend Bergson's famous parallel of the brain as a "central telephonic exchange," whereby the function of the brain is simply that of a node where perceptions get in touch with motor mechanisms, the brain as an instrument limited to the transmission and divisions of movements. Drawing from the history of cybernetics one can trace how Bergson's 'telephonic exchange' prefigures the neural 'cybernetic metaphor.' (...)

  22. Identified Neurons: What If Every Neuron in the Human Brain has its Own Identity?Robert Vermeulen - manuscript
    Recent research suggests that human memories are stored not between neurons as synaptic weights, but within individual neurons themselves. This opens the possibility to replace the dominant paradigm of brain function – neural networks – with a new one. In this article, I explore how “identified neurons” could explain how memories are stored, and how human traits are implemented in the brain.

Cortical Excitability in Patients with Focal Epilepsy: A Study with High Frequency Repetitive Transcranial Magnetic Stimulation (rTMS).Francesca Gilio, Elisa Iacovelli, Maria Gabriele, Elena Giacomelli, Cinzia Lorenzano, Floriana Picchiorri, Anna M. Cipriani, Maria T. Faedda & Maurizio Inghilleri - 2008 - Dialogues in Philosophy, Mental and Neuro Sciences 1 (1):28-32.
    Epileptogenesis involves an increase in excitatory synaptic strength in the brain in a manner similar to synaptic potentiation. In the present study we investigated the mechanisms of short-term synaptic potentiation in patients with focal epilepsy by using 5 Hz repetitive transcranial magnetic stimulation (rTMS), a non invasive neurophysiological technique able to investigate the mechanisms of synaptic plasticity in humans. Ten patients with focal idiopathic cortical epilepsy were studied. 5 Hz-rTMS (10 stimuli-trains, 120% of motor threshold, RMT) (...)

    In the brain the relations between free neurons and the conditioned ones establish the constraints for the informational neural processes. These constraints reflect the systemenvironment state, i.e. the dynamics of homeocognitive activities. The constraints allow us to define the cost function in the phase space of free neurons so as to trace the trajectories of the possible configurations at minimal cost while respecting the constraints imposed. Since the space of the free states is a manifold or a non orthogonal space, (...)

  26. Higher-Order Intentionality and Dretske's View of Analytic Knowledge.Sudan A. Turner - manuscript
    Dretske makes arguments in which he suggests three levels of the intentionality of knowledge: (1) a low level belonging to law-like causal relationships between physical properties, (2) a middle level defined in terms of the intensionality of sentences describing knowledge of these properties, and (3) a highest level of human cognition. Acknowledging the need to explain humans’ analytic knowledge, however, he proposes that we know a proposition P analytically when we know that P entails Q, even though P and Q (...)
