Fig. 3: Experimental results of a 3-neuron circuit.
From: An emergent attractor network in a passive resistive switching circuit
a Energy landscape and transition trajectory of a 3-neuron network that is applied with voltages \({{{{\boldsymbol{v}}}}}_{{{{\bf{1}}}}}=\) [− 1.2; − 0.2; 1.2] V. The red boxes (‘001’ and ’011’) represent the stable states, each of which attracts three other state vectors. b Dependence of the number of stable states on the applied voltage amplitudes. The applied voltages are \({{{\boldsymbol{v}}}}=\alpha {{{{\boldsymbol{v}}}}}_{{{{\bf{1}}}}}\), where \(\alpha\) is increased from 0 to 2. c State transition dynamics of the 3-neuron circuit upon the application of \({{{{\boldsymbol{v}}}}}_{{{{\bf{1}}}}}\), which are monitored in real-time through \({V}_{{BL}}\) (middle panel) in the circuit. The turning points that indicate transitions are marked by red arrows. The middle panel is accompanied by two panels (upper and lower) that show the voltage drop across each device before and after the pulse stimulus. The conductance values in the top and bottom panels represent the initial and final states, respectively. The shaded areas represent the ranges of HCS and LCS, which present a sufficient margin to distinguish the two states in all 8 cases.
