Self-repair is fundamental to biological neural networks. In a neural network with a large number of elements, the probability of failure of each component increases. With the breakdown of each part, there may be a significant ...

We consider spiking neural P systems with astrocytes producing calcium that differs from the standard spiking neural P systems in several ways: we have a new type of resources called calcium unit alongside the standard spike, we have a new type of ...

Modeling the neuronal processes underlying short-term working memory remains the focus of many theoretical studies in neuroscience. In this paper, we propose a mathematical model of a spiking neural network (SNN) which simulates the way a fragment ...

Astrocytes, also described as astroglia, are characteristic star-shaped glial cells in the brain. The important roles of astrocyte such as extracellular regulation, synaptic information regulation, neuronal synchronization and feedback to neural ...

While there is still a lot to learn about astrocytes and their neuromodulatory role in the spatial and temporal integration of neuronal activity, their introduction to neuromorphic hardware is timely, facilitating their computational exploration in ...

Recent neurophysiological findings illustrate that the brain detects the faulty synapses and is able to repair them to some extent. It was shown that retrograde signaling via astrocytes leads to modulation of synaptic activity. Specifically, indirect ...

Neurophysiological experiments have illustrated that astrocytes, the most abundant subtype of the glial cells, have the potential to dynamically regulate and control synaptic transmissions in neural networks. As these cells are able to provide energy ...

Experimental evidences on the role of the synaptic glia as an active partner together with the bold synapse in neuronal signaling and dynamics of neural tissue strongly suggest to investigate on a more realistic neuron-glia model for better ...

We report the first results of simulating the coupling of neuronal, astrocyte, and cerebrovascular activity. It is suggested that the dynamics of the system is different from systems that only include neurons. In the neuron-vascular coupling, ...

Calcium wave oscillations are utilized by astrocytes as a method of cellular communication. These waves are dependent on both an intracellular gap junction pathway involving [Ca^+^+]"i and [IP"3]"i and an extracellular pathway involving [ATP]"o and [Glu]...
