随机共振是一种非线性现象，其中随机噪声优化了系统对信号的响应，已被假设为噪声在大脑信息处理中发挥作用。在这些实验中，使用时变电场将信号和噪声直接传递到哺乳动物大脑的神经元网络。随着场的随机分量的幅度增加，在神经元网络对弱周期信号的响应中观察到共振。这是大脑神经元网络中随机共振的首次演示。
Stochastic resonance, a nonlinear phenomenon in which random noise optimizes a system's response to a signal, has been postulated to provide a role for noise in information processing in the brain. In these experiments, a time varying electric field was used to deliver both signal and noise directly to a network of neurons from mammalian brain. As the magnitude of the stochastic component of the field was increased, resonance was observed in the response of the neuronal network to a weak periodic signal. This is the first demonstration of stochastic resonance in neuronal networks from the brain.
