Intrinsic Neuro-Synaptic Spiking Dynamics in Memristive Networks

Overview

Self-organizing memristive networks are physical circuits that dynamically reconfigure in response to external input signals. This work demonstrates that such networks naturally generate neuronal population spiking dynamics similar to biological neuronal systems, and reveals nonlinear resonance phenomena.

Core Methodology

1. Memristive Network Model

• Physical substrate: Self-organizing memristive circuits with heterogeneous topology
• Dynamics: Intrinsic neuro-synaptic dynamics emerge from voltage-dependent memristance
• Adaptation: Circuitry reconfiguration in response to external input signals

2. Input Signal Analysis

• DC input: Steady-state spiking dynamics characterization
• AC input: Frequency-dependent response analysis
• Resonance: Nonlinear spike-like features maximized at matching frequency

3. Key Findings

1. Networks generate population spiking dynamics resembling biological systems
2. Nonlinear resonance occurs when input frequency matches intrinsic timescale
3. Optimal computational frequency = maximal frequency before resonance onset
4. Heterogeneous topology enables diverse spiking patterns
