Theoretical Basis From String Theory Which Precludes Brain Quantum Computation

We present a theoretical framework grounded in string theory that precludes the possibility of brain-based quantum computation via gravitational modulation. Higher-order corrections to the worldsheet beta function, typically considered negligible in conventional physics, lead naturally to \( f(R) \) gravity in the low-energy effective action. These corrections alter the gravitational wave spectrum by introducing high-frequency scalar curvature modes. As neural systems exhibit low-pass filtering, these high-frequency components become biologically imperceptible. Consequently, action potential timing in axons remains unmodulated, ruling out gravitationally-induced quantum computation in the brain.
