Hi everyone,
I’d like to invite discussion on a theoretical neurophysiological question I’ve been independently exploring.
Hypothesis: Could there exist a large-scale, near-instantaneous Spontaneous Neuroelectrical Cascade (SNC) in the awake human brain?
The idea originates from first-person observations of transient, system-wide bioelectrical events that propagate from the head through the spine and limbs while full consciousness remains intact.
These events appear too rapid to be explained by traditional volume transmission — the slow diffusion of neuromodulators through extracellular fluid (mm/s scale).
This led me to propose a hypothetical mechanism I call the Electro-Volume Interaction (EVI) —
a potential rapid coupling between endogenous electric fields and ionic conductivity within neural and interstitial fluid volumes.
Conceptually:
Volume Diffusion
- Medium: Chemical (neurotransmitters)
- Speed: Slow (mm/s)
- Description: Classical model of volume transmission
Electro-Volume Interaction (EVI)
- Medium: Electrical–ionic coupling
- Speed: Fast (ms-scale)
- Description: Hypothetical field-mediated synchronization
Discussion Points
- Are there known models or studies exploring field–fluid coupling or fast ionic synchronization across tissues?
- Could such events be detectable using high-density EEG, EMG, or ECoG during controlled physiological states?
- Might this relate to large-scale neural field coherence or volume conduction effects?
