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…

TLDR
Comprising consciousness of unobservable quantum information integrated in quantum brain states explains the origin of the inner privacy of conscious experiences and revisits the dynamic timescale of conscious processes to picosecond conformational transitions of neural biomolecules.
Quantum Information in Neural Systems
TLDR
The presented results show that fast decoherence timescales could assist cognitive binding through quantum entanglement across extensive neural networks in the brain cortex, and show that quantum coherence of individual subsystems cannot be used for cognitive binding because it is a physical mechanism that leads to separability and non-interaction.
Quantum No-Go Theorems and Consciousness
Our conscious minds exist in the Universe, therefore they should be identified with physical states that are subject to physical laws. In classical theories of mind, the mental states are identified
Inner privacy of conscious experiences and quantum information
TLDR
Identifying consciousness with the unobservable quantum information contained by quantum physical brain states allows for application of quantum information theorems to resolve possible paradoxes created by the inner privacy of conscious experiences, and explains how the observable brain is constructed by accessible bits of classical information that are bound by Holevo's theorem.
The quantum physics of synaptic communication via the SNARE protein complex.
TLDR
A molecular upgrade of the Beck and Eccles model of neurotransmitter release at synapses in the human cerebral cortex is provided by identifying the quantum quasiparticles as Davydov solitons that twist the protein α-helices and trigger exocytosis of synaptic vesicles through helical zipping of the SNARE protein complex.

TLDR
A quantum mechanical model for exocytosis, a quantal phenomenon of the presynaptic vesicular grid with a probability much less than 1, is presented based on a tunneling process of the trigger mechanism.
How Dirac's Seminal Contributions Pave the Way for Comprehending Nature's Deeper Designs
Credible reasons are presented to reveal that many of the lingering century old enigmas, surrounding the behavior of at least an individual quantum particle, can be comprehended in terms of an
Computational capacity of pyramidal neurons in the cerebral cortex
TLDR
Physical estimates of the total number and type of ions involved in neuronal electric spiking based on the obtained morphometric data, combined with energetics of neurotransmitter release and signaling fueled by glucose consumed by the active brain, support highly efficient cerebral computation performed at the thermodynamic allowed Landauer limit for implementation of irreversible logical operations.
Probability of transmitter release at neocortical synapses at different temperatures.
TLDR
The results of the present study show that release probabilities at synapses formed onto layer 2/3 pyramidal cells in the visual cortex vary significantly, but values >0.3 are rare and the results obtained either at room or variable temperature differ significantly from those made under conditions of constant temperature in the physiological range.
