Research on glial cells over the past 30 years has confirmed critical role of astrocytes in pathophysiological brain states. However, most our knowledge about astrocyte physiology and interactions between neurons is based premises that constitute a homogeneous cell type, without considering particular properties circuits or nuclei which are located. Therefore, we argue more-sophisticated experiments required to elucidate specific features different regions, even within layers circuit. Thus, addition diverse mechanisms used by communicate with synaptic partners, it necessary take into account cellular heterogeneity likely contributes outcomes astrocyte-neuron signaling. In this review article, briefly summarize current data regarding anatomical, molecular functional communication, as well communication.

While neurons principally mediate brain function, astrocytes are emerging as cells with important neuromodulatory actions in physiology. In addition to homeostatic roles, respond neurotransmitters calcium transients stimulating the release of gliotransmitters that regulate synaptic and neuronal functions. We investigated astrocyte-neuronal network interactions vivo by combining two-photon microscopy monitor astrocyte electrocorticogram record activity somatosensory cortex during sensory stimulation. found stimuli a stimulus-dependent manner. Sensory elicit surge gamma range (30-50 Hz) followed delayed dampens steady-state activity. This sensory-evoked increase is enhanced transgenic mice impaired signaling decreased pharmacogenetic stimulation astrocytes. Therefore, cortical inputs maximizing its dynamic range.

Abstract Interneurons play a critical role in precise control of network operation. Indeed, higher brain capabilities such as working memory, cognitive flexibility, attention, or social interaction rely on the action GABAergic interneurons. Evidence from excitatory neurons and synapses has revealed astrocytes integral elements synaptic transmission. However, interneurons can also engage astrocyte signaling; therefore, it is tempting to speculate about different scenarios where, based particular interneuron cell type, GABAergic‐astrocyte interplay would be involved diverse outcomes function. In this review, we will highlight current data supporting existence dynamic communication its impact inhibitory‐regulated responses, bringing new perspectives ways might contribute efficient neuronal coding.

Astrocytes respond to and regulate neuronal activity, yet their role in mammalian behavior remains incompletely understood. Especially unclear is whether, if so how, astrocyte activity regulates contextual fear memory, the dysregulation of which leads pathological fear-related disorders. We generated GFAP-ChR2-EYFP rats allow specific activation astrocytes vivo by optogenetics. found that after memory acquisition within a temporal window, disrupted consolidation persistently decreased but not cued accompanied reduced anxiety behavior. In microdialysis experiments showed photoactivation increased extracellular ATP adenosine concentrations. Intracerebral blockade A 1 receptors (A Rs) reversed attenuation memory. Furthermore, intracerebral or intraperitoneal injection R agonist mimicked effects activation. Therefore, our findings provide deeper understanding astrocyte-mediated regulation suggest new important therapeutic strategy against

Synchronization of neuronal activity in the brain underlies emergence oscillations termed ‘Brain waves’, which serve various physiological functions and correlate with different behavioural states. It has been postulated that at least ten distinct mechanisms are involved formulation these waves, including variations concentration extracellular neurotransmitters ions, as well changes cellular excitability. In this mini-review, we highlight contribution astrocytes, a subtype glia, formation modulation waves mainly due to their close association synapses allows bidirectional interaction neurons, syncytium-like via gap junctions facilitate communication distal regions through Ca2+ waves. These capabilities allow astrocytes regulate excitability glutamate uptake, gliotransmission tight control K+ levels process clearance.
