Detection of M-Sequences from Spike Sequence in Neuronal Networks

Figure 7

An equivalent 3-stage LFSR. (a) Model 1: spikes of multiple neurons in a neuron group propagate to another neuron group like synfire chain. Although we assume that neurons in the same neuron group evoke simultaneously and all pair of neurons are equal in their synaptic delay, there is a possibility that an equivalent LFSR circuit is assembled when the spike timing delay of each neuron in a same neuron group and synaptic delay between neuron groups are coordinated even if pair of neurons are not equal in their synaptic delay. (b) Model 2: the framework of LFSR is constructed by “mainneurons” and “sub neurons” are connected with “mainneurons” to excite them. Although, we omit a XOR function in both figures, some XOR circuit models constructed by neurons are already shown in previous study.
