The present invention relates to a neural network information transmitting method and system. The method comprises the following steps that: routing information corresponding to neuron information is obtained based on the neuron information calculated by a current neuron, wherein the routing information contains the information of all routing neurons through which the neuron information passes when the neuron information is transmitted to a target neuron from the current neuron, and connection information of all the routing neurons; delay information corresponding to the routing information is obtained according to the routing information; and the neuron information is outputted according to the neuron information and the delay information. According to the neural network information transmitting method and system of the invention, the delay information is considered in the output information of the neuron, so that the neuron information can carry more abundant time domain information, the operation mode of the neuron is enriched, and the generalization ability of a whole network is enhanced.
