Testing quantum-like markers in neural dynamics

Partha Ghose and Dimitris Pinotsis have proposed two experiments to identify quantum-like markers in neural dynamics, published in a revised arXiv paper (arXiv:2508.21490v2). The first experiment tests whether power spectra from subthreshold oscillations in neuronal cultures follow classical FitzHugh-Nagumo equations or a quantum variant. The second examines if propagation statistics of electrical activity in axons align with the classical diffusive cable equation or a quantum version. These experiments aim to detect quantum effects in neural processes, potentially revealing a quantum basis for cognition.

This work bridges quantum physics and neuroscience by adapting well-known neural equations to include quantum terms. If successful, the experiments could provide evidence for quantum coherence in brain activity, challenging classical models of neural computation. The findings could impact fields like quantum biology and artificial intelligence, offering new insights into how quantum mechanics might influence information processing in the brain.
