Abstract Impaired brain function is restored following injury through dynamic processes that involve synaptic plasticity. This restoration supported by the brain’s inherent modular organization, which promotes functional separation and redundancy. However, it remains unclear how structure interacts with plasticity, most notably in form of spike-timing-dependent plasticity (STDP), to define damage response recovery efficiency. In this work, we numerically modeled a neuronal network vitro...
Neuronal networks in dissociated culture combined with cell engineering technology offer a pivotal platform to constructively explore the relationship between structure and function living neuronal networks. Here, we fabricated defined possessing modular architecture on high-density microelectrode arrays (HD-MEAs), state-of-the-art electrophysiological tool for recording neural activity high spatial temporal resolutions. We first established surface coating protocol using cell-permissive...
We study how reliably generalized synchronization can be detected and characterized from time-series analysis. To that end, we analyze in a sense of delay-coupled chaotic oscillators unidirectional ring configurations. The condition verified via the auxiliary system approach; however, practice, this might not always possible. Therefore, study, widely used indicators to directly quantify phase noise-free time series two are employed complementarily approach. In our analysis, none indices...
This paper proposed a packet drop probability function with an adjustable nonlinearity parameter in random early detection (RED) for active queue management of router to control network congestion. We investigated the effect on average size, throughput, retransmission rate, round-trip time, and fairness index two widely used loss-based congestion algorithms: Reno CUBIC. Simulations were performed Tail-Drop original RED clarify under different traffic loads. The results showed that nonlinear...
The first electrophysiological evidence of the phenomenon traveling electrical waves produced by populations interneurons within spinal cord was reported our interdisciplinary research group. Two interesting observations derive from this study: first, negative spontaneous dorsum potentials (CDPs) that are superimposed on propagating sinusoidal not correlated with any scratching phase; second, these CDPs do propagate along lumbosacral segments, but they appear almost simultaneously at...
The field of physical reservoir computing, which harnesses the dynamics systems for information processing, is undergoing continuous development. use cultured neuronal networks as a system within computing has played crucial role in clarifying connection between network structure and processing. In this study, we introduce model that combines predictive coding neurons, serving sensory Our findings indicate interplay number neurons significant influence on This research lays groundwork future...
Recent studies in the field of neuroscience have reported that neuronal avalanches are observed cultured cortical slice brain. The considered as one mechanisms memory functions However, it still remains elusive what is a key factor to produce avalanches. To clarify this issue, we spike-timing-dependent plasticity (STDP) candidate for mechanism induce because STDP constructs functional circuits. In paper, based on idea, analyzed activities networks constructed through from viewpoints...
Specific memory might be stored in a subnetwork consisting of small population neurons. To select neurons involved formation, neural competition essential. In this paper, we show that excitable are competitive and organize into two assemblies recurrent network with spike timing-dependent synaptic plasticity (STDP) axonal conduction delays. Neural is established by the cooperation spontaneously induced oscillation, delays, STDP. We also suggest mechanism paper one basic functions required to...
Abstract Homoclinic bifurcation is observed in DC–DC converters; this may affect the qualitative characteristics of converters with photovoltaic modules. However, no papers have reported appearance homoclinic or analyzed phenomenon mathematically. As first step toward understanding dynamical mechanism, article investigates modules expressed by piecewise‐linear characteristics. © 2019 Institute Electrical Engineers Japan.
