claimThe author of the entry 'Quantum Approaches to Consciousness' received comments from Guido Bacciagaluppi, Friedrich Beck, Thomas Filk, Stuart Hameroff, Hans Primas, Henry Stapp, and an anonymous referee that improved an earlier version of the manuscript.
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 (2001) suggested that quantum stochastic resonance is a possibility for achieving ordered patterns at the level of neuronal assemblies from fundamentally random synaptic processes, though this remains an unsolved problem.
quoteFriedrich Beck stated in 2001 that science, by its very nature, cannot provide answers to questions related to the mind.
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.
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.

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.
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.
