Detection of M-Sequences from Spike Sequence in Neuronal Networks

Figure 1

3-stage LFSR circuit, the operation at the ring sum is an exclusive-OR such as 1+0=1 and 1+1=0. (a) A basic circuit with feedback [2, 3] generates an M-sequence as 10111001011100…(basic pattern). (b) A mirror circuit of (a) with feedback [1, 3] generates a time course of reversed-order M-sequence, as 11101001110100….
