The brain and LLMs face the same fundamental problems. But the brain solved them first while running on only 2.5 watts for informational processing. How is that possible? Jack Tuszynski and I were invited by Azrieli College of Engineering to present our recent paper published in Frontiers in Human Neuroscience. The scope of the presentation was to connect the paper's mechanism to LLM system design, which turned out to be a incredible thread to pull on because the brain and LLMs face incredibly very problems as the first slide walks through. The paper proposes that the brain switches between two computational modes, a fast parallel quantum-enhanced regime and a slower classical sequential regime, and that self-referential processing through the default mode network is the biological mechanism that controls the switch. If this mechanism is even partially correct, it has real implications for how we think about attention, compression, and mode-switching in artificial systems. It was an honor to present and we could have gone on for another few hours easily. Jack walked through the biophysics of microtubules, quantum coherence at the nanometer scale, the CaMKII memory encoding mechanism, and the experimental evidence for quantum states in tubulin, and then the Q&A walked through energy pumping and the process at the cytoskeletal level. We're very grateful to Azrieli for the generous invitation and for the wonderful questions. 0:00 - Shared Problems Between the Brain and LLMs 3:04 - Flow States and the Origin of the Hypothesis 4:16 - The Double Slit Experiment Parallel 5:40 - System 1, System 2, and the Missing Mechanism 7:04 - Roger Penrose and Non-Algorithmic Computation 9:02 - Quantum Cognition and the Noise Hypothesis 10:14 - Vervaeke, Ferraro, and the Selection Pressure for Two Modes 12:45 - Carhart-Harris and the Entropic Brain Hypothesis 13:50 - The Default Mode Network as the Switch 14:55 - 66% of Ego Dissolution Explained by Alpha in the PCC 15:49 - Connecting to Flow Research (Leroy and Cheron 2020) 17:10 - Predictions from DMN to Tubulin Dimers 19:47 - The Formal Hypothesis and the Full Mechanism 22:40 - Q&A on DMN, Quantum Activity, and Free Will 25:13 - Jack Tuszynski: Inside the Neuron 29:00 - ATP, Mitochondria, and Biophotons 30:15 - Microtubules and Tubulin Dimers 33:01 - Microtubule Functions and Parallel Bundles 35:48 - Stuart Hameroff and Orchestrated Objective Reduction 37:08 - C-Termini and Electromagnetic Sensitivity 39:40 - Quantum Properties of Microtubules 41:05 - Microtubule Associated Proteins and Alzheimer's 42:08 - Memory Storage Capacity in Microtubules 43:45 - CaMKII and Memory Encoding 46:36 - Quantum States in Tubulin Dimers (Kalra et al.) 49:51 - Q&A: Is Mental Energy Physical Energy? 54:38 - Q&A: Is Memory Distributed or Localized? 56:56 - Closing Thoughts
