Transmission and detection of biharmonic envelope signal in a feed-forward multilayer neural network

Abstract In this work, we investigate in detail the biharmonic envelope signal propagation in a feed-forward multilayer neural network where the biharmonic signals are only on the first layer. We reveal that three signal propagation modes induced high-frequency force, including damped propagation (DP), asynchronous excited propagation (EP), and accurate propagation (AP), are observed under the different parameter settings. Interestingly, under the condition of damped propagation and asynchronous excited propagation, channel noise can induce accurate signal transmission. All these findings may light on our understanding of signal transmission and signal encoding in the brain.
