    Brain computing power may be enhanced by microphysical processes, utilizing molecular switches for biological functions. This links macroscopic brain activity to microscopic neuron membrane signaling.

    Area of Science:

    • Neuroscience
    • Computational Neuroscience
    • Quantum Biology

    Background:

    • The brain's computational capacity is a subject of ongoing research.
    • Understanding the link between macroscopic brain function and microscopic processes is crucial.
    • Existing models do not fully account for the brain's immense processing power.

    Purpose of the Study:

    • To explore the hypothesis that microphysical processes enhance brain computing power.
    • To propose models for how molecular switching could support biological functions.
    • To consider the implications of information flow between microscopic and macroscopic scales.

    Main Methods:

    • Review of experimental findings on neuron membrane chemical messengers.
    • Theoretical arguments based on computational limits, parallelism, and evolution.
