AI Insight
This paper proposes two experimental approaches to detect potential quantum-like behaviors in neural activity. The first experiment tests whether subthreshold oscillations in neuronal cultures conform to classical Fitzgugh-Nagumo equations or a quantum variant, while the second examines whether electrical signal propagation in axons follows classical diffusive cable equations or quantum alternatives. Both experiments aim to identify distinguishing signatures that could indicate quantum processes operating in neural systems.
Why it matters
If quantum effects are found to play a role in neural dynamics, it could fundamentally change our understanding of how the brain processes information and potentially inform new approaches to artificial intelligence and neurological treatments. The proposed experiments provide testable methods to investigate whether quantum mechanics contributes to neural computation beyond classical physics.

Abstract: We propose two experiments for identifying quantum markers in neural data based on quantum variants of well-known equations for neural activity that describe electrical signal propagation on axonal arbors and dendrites. These include (i) testing if power spectra from subthreshold oscillations in neuronal cultures follow the classical Fitzgugh-Nagumo equations or a recently introduced quantum variant of them and (ii) testing if propagation statistics of electrical activity in axons follow the classical diffusive cable equation or a quantum variant of it.
