Astrocytes regulate cortical state switching in vivo

KE Poskanzer, R Yuste - Proceedings of the National …, 2016 - National Acad Sciences
The role of astrocytes in neuronal function has received increasing recognition, but
disagreement remains about their function at the circuit level. Here we use in vivo two …

Astrocytes modulate sensory-evoked neuronal network activity

J Lines, ED Martin, P Kofuji, J Aguilar… - Nature communications, 2020 - nature.com
While neurons principally mediate brain function, astrocytes are emerging as cells with
important neuromodulatory actions in brain physiology. In addition to homeostatic roles …

Disentangling calcium-driven astrocyte physiology

DA Rusakov - Nature Reviews Neuroscience, 2015 - nature.com
Astrocytes seem to rely on relatively sluggish and spatially blurred Ca2+ waves to
communicate with fast and point-precise neural circuits. This apparent discrepancy could …

Astrocyte calcium signalling orchestrates neuronal synchronization in organotypic hippocampal slices

T Sasaki, T Ishikawa, R Abe… - The Journal of …, 2014 - Wiley Online Library
Key points In the brain, astrocytes detect neuronal activity and regulate neuronal excitability
and synaptic transmission. Recent studies show that calcium elevations that are localized …

Neuronal activity regulates correlated network properties of spontaneous calcium transients in astrocytes in situ

F Aguado, JF Espinosa-Parrilla… - Journal of …, 2002 - Soc Neuroscience
Spontaneous neuronal activity is essential to neural development. Until recently, neurons

Locally synchronized astrocytes

T Sasaki, N Kuga, S Namiki, N Matsuki… - Cerebral cortex, 2011 - academic.oup.com
Astrocytes exhibit spontaneous calcium fluctuations. These activities have not been
captured by large-scale recordings, and little is known about their collective dynamics. In situ …

Centripetal integration of past events in hippocampal astrocytes regulated by locus coeruleus

P Rupprecht, SN Duss, D Becker, CM Lewis… - Nature …, 2024 - nature.com
An essential feature of neurons is their ability to centrally integrate information from their
dendrites. The activity of astrocytes, in contrast, has been described as mostly …

Rapid astrocyte calcium signals correlate with neuronal activity and onset of the hemodynamic response in vivo

IR Winship, N Plaa, TH Murphy - Journal of Neuroscience, 2007 - Soc Neuroscience
