NEURON-GLIA NETWORKS: INTEGRAL GEAR OF BRAIN FUNCTION

Frontiers in Cellular Neuroscience, 2014
Astrocytes, the most abundant glial cell in the brain, play critical roles in metabolic and homeostatic functions of the Nervous System; however, their participation in coding information and cognitive processes has been largely ignored.

Exploring the Production of Extracellular Matrix by Astrocytes in Response to Mimetic Traumatic Brain Injury [PDF]

, 2016
Following injury to the central nervous system, extracellular modulations are apparent at the site of injury, often resulting in a glial scar. Astrocytes are mechanosensitive cells, which can create a neuroinhibitory extracellular environment in response

Calcium imaging and BAPTA loading of amygdala astrocytes in mouse brain slices

STAR Protocols, 2022
Summary: Astrocytes are glial cells that exhibit calcium signaling-mediated activity. Here, we present a protocol to monitor and manipulate astrocyte calcium activity from mouse amygdala slices.

Astrocyte dynamics revisited [PDF]

A vast amount of experimental evidence hints that astrocytes could be active players in information processing of the brain. It remains unclear nevertheless how these cells could encode synaptic stimuli through variations of their intracellular Ca2 ...

A Mathematical Model of Tripartite Synapse: Astrocyte Induced Synaptic Plasticity

, 2012
In this paper we present a biologically detailed mathematical model of tripartite synapses, where astrocytes modulate short-term synaptic plasticity. The model consists of a pre-synaptic bouton, a post-synaptic dendritic spine-head, a synaptic cleft and ...

Interactions between Sirt1 and MAPKs regulate astrocyte activation induced by brain injury in vitro and in vivo

Journal of Neuroinflammation, 2017
Background Astrocyte activation is a hallmark of traumatic brain injury resulting in neurological dysfunction or death for an overproduction of inflammatory cytokines and glial scar formation.

Sequence learning in Associative Neuronal-Astrocytic Network [PDF]

arXiv, 2017
The neuronal paradigm of studying the brain has left us with limitations in both our understanding of how neurons process information to achieve biological intelligence and how such knowledge may be translated into artificial intelligence and its most brain-derived branch, neuromorphic computing. Overturning our fundamental assumptions of how the brain

αVβ3 Integrin regulates astrocyte reactivity

Journal of Neuroinflammation, 2017
Background Neuroinflammation involves cytokine release, astrocyte reactivity and migration. Neuronal Thy-1 promotes DITNC1 astrocyte migration by engaging αVβ3 Integrin and Syndecan-4.
