TL;DR

This paper proposes a dynamical theory of mind-brain interaction based on quantum nonlocality, arguing that the rejection of classical causation in favor of quantum principles enables a coherent explanation of consciousness as a physical process that influences brain function. It demonstrates that quantum-based models naturally account for cognitive phenomena like attentional bottlenecks, workload perception, and short-term memory, offering superior explanatory power over classical alternatives.

ABSTRACT

Orthodox Copenhagen quantum theory renounces the quest to understand the reality in which we are imbedded, and settles for practical rules that describe connections between our observations. However, an examination of certain nonlocal features of quantum theory suggests that the perceived need for this renunciation was due to the uncritical importation from classical physics of a crippling metaphysical prejudice, and that rejection of that prejudice opens the way to a dynamical theory of the interaction between mind and brain that has significant explanatory power.

Motivation & Objective

• To challenge the Copenhagen interpretation's rejection of physical reality and propose a dynamical theory of mind-brain interaction grounded in quantum nonlocality.
• To resolve the mind-body problem by showing that consciousness can be a physical process that influences brain dynamics through quantum effects.
• To explain empirical cognitive phenomena—such as attentional bottlenecks, workload perception, and memory storage—using a quantum-based framework.
• To demonstrate that quantum models provide a more natural and unified explanation of cognition than classical models requiring ad hoc assumptions.
• To argue that the quantum Zeno effect and nonlocal correlations offer a physical basis for the observed link between mental effort and physical force output.

Proposed method

• Analyzes experimental quantum nonlocality (e.g., 10 km photon entanglement) to argue that nonlocality is a real feature of nature, not just a mathematical artifact.
• Applies the idea of nonlocality to propose that conscious acts can influence distant brain states via quantum correlations, bypassing classical causation.
• Uses the quantum Zeno effect to model how sustained conscious attention can stabilize brain states, opposing spontaneous evolution under the Schrödinger equation.
• Models consciousness as the selection of a quasi-classical state subensemble compatible with a consciously accepted course of action.
• Integrates cognitive data (e.g., workload ratings, performance trade-offs) into a quantum-theoretic framework where processing capacity is quantified in bits per second.
• Compares classical and quantum models of central processing, showing that quantum models automatically enforce a bottleneck without ad hoc assumptions.

Experimental results

Research questions

• RQ1 Can quantum nonlocality provide a physical basis for mind-brain interaction, replacing the epistemological limitations of the Copenhagen interpretation?
• RQ2 How can consciousness be modeled as a physical process that influences brain dynamics without violating relativity or classical causality?
• RQ3 Why do attentional bottlenecks and workload perceptions arise in cognitive tasks, and can they be explained by quantum principles?
• RQ4 What is the role of the quantum Zeno effect in sustaining conscious attention and its influence on physical force output?
• RQ5 How does the separation of short-term memory storage from conscious selection emerge naturally in a quantum-theoretic model of cognition?

Key findings

• Quantum nonlocality, confirmed by experiments over 10 km, demonstrates that measurement outcomes on entangled particles are correlated instantaneously, defying classical locality.
• The theory explains that conscious selection of a course of action corresponds to the actualization of a specific quasi-classical state, which then evolves autonomously.
• Mental effort correlates with the rate of conscious events, and this rate is proportional to the number of bits per second of processing capacity, consistent with empirical workload data.
• The quantum Zeno effect explains why physical force output diminishes when attention is divided: sustained attention opposes spontaneous quantum evolution, and this opposition is reduced when capacity is shared.
• Short-term memory can be stored in persistent brain activity patterns without conscious involvement, while deliberate memory operations require conscious effort and thus consume limited processing capacity.
• The theory accounts for the independence of perceptual processing from central processing: front-end perception and STM storage operate in parallel, while conscious control is serial and bottlenecked.
