Quantum Approaches to Consciousness plato.stanford.edu Nov 30, 2004 8 facts
claimJohn Eccles proposed that the fundamentally indeterministic nature of individual quantum state collapses in the brain provides an entry point for mental causation, allowing mental powers to influence brain states.
quoteFriedrich Beck and John Eccles (1992) stated: “mental intention (volition) becomes neurally effective by momentarily increasing the probability of exocytosis”.
claimFriedrich Beck and John Eccles' approach to consciousness focuses primarily on brain states and brain dynamics, with the exception of John Eccles' specific ideas regarding mental causation.
claimFriedrich Beck and John Eccles (1992) assert that quantum processes are distinguishable from thermal processes for energies higher than 10^-2 eV at room temperature.
referenceFriedrich Beck and John Eccles proposed in the 1990s that mental intentions can influence quantum mechanical processes relevant to exocytosis at the synaptic cleft.
claimThe quantum trigger mechanism proposed by Friedrich Beck and John Eccles (1992) yields a probability of exocytosis between 0 and 0.7, which aligns with empirical observations.
referenceKarl Popper and John C. Eccles authored 'The Self and Its Brain', published by Springer in 1977.
referenceThe trigger mechanism proposed by Friedrich Beck and John Eccles (1992) utilizes the quantum concept of quasi-particles to describe tunneling processes of two-state quasi-particles, which result in state collapses.
Quantum Approaches to Consciousness plato.stanford.edu Nov 30, 2004 5 facts
claimThe quantum consciousness approach developed by Friedrich Beck and John Eccles, and refined by Matthew Fisher, provides a detailed application of standard quantum mechanics to the process of exocytosis.
claimFriedrich Beck and John Eccles proposed that quantum mechanics plays a role in brain processes, specifically regarding information transfer at the synaptic cleft.
claimBeck and Eccles suggested in the 1990s that quantum mechanical processes relevant to exocytosis at the synaptic cleft can be influenced by mental intentions.
claimThe quantum consciousness approach by Friedrich Beck and John Eccles fails to explain how the activity of single synapses influences the dynamics of neural assemblies and leaves the mental causation of quantum processes as an unproven claim.
claimHenry Stapp and the team of Friedrich Beck and John Eccles propose that the ontic randomness of quantum events provides a mechanism for mental causation, allowing conscious mental acts to influence brain activity.
Non-physicalist Theories of Consciousness cambridge.org Dec 20, 2023 3 facts
claimJohn Eccles and Karl Popper argued that epiphenomenalism makes the evolution of consciousness inexplicable because it renders consciousness inert and useless, and useless features do not evolve.
claimInteractionist dualists, such as John Eccles and Karl Popper in 1977, have proposed that consciousness influences the outcome of quantum collapse.
claimFriedrich Beck and John Eccles (1992) and Stuart Hameroff and Roger Penrose (2016) have proposed concrete mechanisms for how quantum coherence might occur in the brain despite environmental noise.
The Hard Problem of Consciousness | Springer Nature Link link.springer.com 2 facts
claimFriedrich Beck and John Eccles hypothesized in 1992 that mental intention becomes neurally effective by momentarily increasing the probability of exocytosis in selected cortical areas, thereby generating increased excitatory post-synaptic potentials (EPSPs) without violating physical conservation laws.
claimFriedrich Beck and John Eccles proposed that the interaction of mental events with quantum probability amplitudes for exocytosis creates a coherent coupling of individual amplitudes across hundreds of thousands of boutons in a dendron, leading to a variety of modes in brain activity.
Moving Forward on the Problem of Consciousness - David Chalmers consc.net 2 facts
referenceJohn Eccles proposed a theory where 'psychons' in the mind affect physical processes in the brain, but this theory remains subject to an epiphenomenalist worry because the experiential nature of psychons is inessential to the dynamic causal story.
claimTheories involving Cartesian ectoplasm, Benjamin Libet's 'conscious mental field', and the views advocated by Henry Stapp and David Hodgson are all subject to the same epiphenomenalist worry as John Eccles' psychon theory, where the experiential quality of the mental states is inessential to the causal explanation of behavior.

claimJohn Eccles argues that special anatomical and physical adaptations of the mammalian cerebral cortex gave rise to consciousness.

perspectiveNeurologists Charles Sherrington and John Eccles defended dualism as the only theory capable of preserving the data of consciousness.
Consciousness and Cognitive Sciences journal-psychoanalysis.eu 1 fact
claimThe authors of 'Consciousness and Cognitive Sciences' categorize naturalistic approaches to cognitive science into a spectrum, explicitly excluding traditional dualistic stances (such as those held by J. C. Eccles) and theories proposed by quantum mechanics proponents.
