“…Many neuropathological disorders such as epileptic seizures [9], Parkinson's disease [10], and sleep-related disturbances [11] are required to be carefully studied in order to discover possible pathways for diagnostic and treatment approaches. In recent years, bidirectional interaction between astrocytic network and neuronal activity have been determined in the area of computational neuroscience.…”

Astrocyte cells, the most existing abundant cells in central nervous system, play an essential role in modulating the neuronal activities, information processing, and regulating the synaptic plasticity through calcium (Ca2+) fluctuations of ions hemostasis by using a feedback mechanism. The pathophysiological and hypersynchronous neuronal activity can lead to the epileptic seizures, which is known as one of the neurodegenerative disorders in the field of neuroscience. This paper presents a modified neuron-astrocyte interaction (tripartite synapse) model based on leaky and integrate fire neuron and the astrocyte-synapse models using an area-efficient hardware approach called stochastic computing paradigm. The proposed model is synthesized physically on field-programmable gate array as a proof of concept. The implementation results of the presented model can mimic the bidirectional communication in biological minimal network of pre-postsynaptic and Ca2+-based model for astrocyte with considerably lower hardware cost. The influence of astrocytes on neural network behavioral has been investigated by providing a proper feedback mechanism and considering the role of gap junction coupling and the various coefficients on desynchronizing the impaired synchronization of the coupled neurons.INDEX TERMS Astrocytes, Desynchronization, Field programmable gate array (FPGA), Neural-Glial interaction.

As an important subtype of GABAergic interneurons, parvalbumin (PV) interneurons play a critical role in regulating cortical circuits and neural networks. Abnormalities in the development or function of PV interneurons have been linked to autism spectrum disorder (ASD), a neurodevelopmental disorder characterized by social and language deficits. In this review, we focus on the abnormalities of PV interneurons in ASD, including quantity and function and discuss the underlying mechanisms of impairments in PV interneurons in the pathology of ASD. Finally, we propose potential therapeutic approaches targeting PV interneurons, such as transplanting MGE progenitor cells and utilizing optogenetic stimulation in the treatment of ASD.
