It is unclear whether quantum phenomena can be observed in brain recordings because of thermal noise causing decoherence, that is, quantum superpositions and entanglement quickly collapsing into classical, i.e. non-quantum states. This paper first demonstrates that neuronal noise of the Brownian motion type is mathematically equivalent to a wave-particle description of the kind predicted by a fundamental equation in quantum mechanics known as the Schrödinger equation. It then extends the considerations to the more realistic FitzHugh-Nagumo model which has been widely used to describe neuronal dynamics. This approach could provide new insights into the underlying mechanisms of brain function.
由于热噪声会导致退相干，即量子叠加和纠缠迅速坍缩为经典的（即非量子的）状态，因此目前尚不清楚能否在大脑记录中观察到量子现象。本文首先证明，布朗运动类型的神经元噪声在数学上等同于量子力学中一个基本方程（即薛定谔方程）所预测的那种波粒描述。然后将这些考虑扩展到更现实的、被广泛用于描述神经元动力学的菲茨休 - 纳古莫模型。这种方法可能为大脑功能的潜在机制提供新的见解。
