  author={F J Binm{\"o}ller and Christian M. M{\"u}ller},
Intercellular coupling among astrocytes was studied in rat visual cortex slices from animals aged 1 week to 4 months. Cell coupling via gap junctions was determined by the dye spread of the low molecular weight dye Lucifer Yellow CH injected into electrophysiologically identified cells to adjacent cells. Coupling among glial cells was first detected at postnatal day 11 and was thereafter consistently observed until adulthood. Dye spread was observed up to 300 μm radially from the injected cell… 
Astrocytic dye coupling in rat hippocampus: Topography, developmental onset, and modulation by protein kinase C
Although no compartmentalization was seen with respect toAstrocytic coupling, the intercellular communication of these glial cells has the capability of being regulated for example by neuronal signals which activate the phospholipase C pathway in astrocytes.
Morphology of astrocytes and oligodendrocytes during development in the intact rat optic nerve
Analysis of oligodendrocyte growth suggests that these cells did not myelinate axons in a random manner and that axons may influence the myelinating processes of nearby oligodendedrocytes.
Electrical coupling among Bergmann glial cells and its modulation by glutamate receptor activation
The studies indicate that electrical coupling between Bergmann glial cells is not only developmentally regulated but also controlled by physiological stimuli.
Seasonal changes in astrocytes parallel neuronal plasticity in the song control area HVc of the canary
The data indicate that the astrocytic population in the avian forebrain undergoes significant changes coincident with the known functional changes in the vocal control nuclei during periods of song production.
Development of gap junctions in hippocampal astrocytes: evidence that whole cell electrophysiological phenotype is an intrinsic property of the individual cell.
It is found that passive astrocytes, which predominate after 3 wk postnatally, have much lower membrane resistances (Rm) and are more frequently dye coupled and to more cells, than outwardly and variably rectifying astroCytes that predominated in early postnatal development.
Distinct Populations of Identified Glial Cells in the Developing Rat Spinal Cord Slice: Ion Channel Properties and Cell Morphology
The glial cells in the spinal cord slices possess distinct morphological, immunohistochemical and physiological properties, and that the glial populations undergo changes during postnatal development.
Postnatal development of ionic currents in rat hippocampal astrocytes in situ.
Developmental changes in ion channel expression and cell morphology were studied in glial cells with the use of whole cell patch-clamp recordings in rat [postnatal day (P)5-P50] hippocampal slices.
Gap Junction-Mediated Astrocytic Networks in the Mouse Barrel Cortex
Combination of dye-coupling experiments performed with biocytin and immunostaining with specific cell markers demonstrated that astrocytic networks do not involve neurons, oligodendrocytes or NG2 cells, and indicated a preferential orientation of coupling inside the barrels resulting from subpopulations of astROcytes with different coupling properties that contribute to shaping astroCytic networks.
Astrocytes exhibit regional specificity in gap‐junction coupling
Differences in coupling indicate differences in the number of gap‐junction connections in astrocytes cultured from the six central nervous system regions, which may reflect the adaptation of astracytes to varying functional requirements in different CNS regions.
Homotypic and Heterotypic Coupling Mediated by Gap Junctions During Glial Cell Differentiation In Vitro
Intercellular communication mediated by gap junctions was investigated during oligodendrocyte differentiation in primary and secondary cell cultures from newborn and adult rats, finding a developmental pattern comparable to homotypic dye‐coupling between oligodendedrocytes.


Specificity of cell-cell coupling in rat optic nerve astrocytes in vitro.
The specificity of cell coupling in cultured rat optic nerve astrocytes suggests that predominantly A2B5- astroCytes comprise a coupled glial syncytium; this physiological feature of these cells may be a specialized adaptation for "spatial buffering," the transport of K+ away from areas of focal extracellular accumulation.
Carbon dioxide sensitivity of dye coupling among glia and neurons of the neocortex
The results suggest that coupling between cortical glia is very sensitive to cytoplasmic acidification, and the relative insensitivity of neuronal coupling to CO2 may indicate either that the conductance of neuronal gap junctions is only weakly affected by pHi or that neuron-to-neuron dye passage occurs via other types of intercytopLasmic pathways.
Visualization of oligodendrocytes and astrocytes in the intact rat optic nerve by intracellular injection of lucifer yellow and horseradish peroxidase
The morphology of glial cells in the intact rat optic nerve, a central nervous system (CNS) white matter tract, was analysed by filling over 500 macroglial cells intracellularly with horseradish
Dark‐rearing retards the maturation of astrocytes in restricted layers of cat visual cortex
The present study investigates the effects of dark‐rearing on astroglial characteristics as determined by immunostaining for glial fibrillary acidic protein (GFAP) and the S‐100 protein and concludes that astrocytic maturation in the visual cortex is influenced by neuronal activity.
Electrical coupling between astrocytes and between oligodendrocytes studied in mammalian cell cultures
The strong electrical coupling among astrocytes, in concert with their K+‐selective membrane conductance, would provide for an electrical syncytium well designed to transport K+ away from areas of focal extracellular accumulation (i.e., the spatial buffer mechanism), and these cells, more than oligodendrocytic cells, may provide this function.
A qualitative and quantitative ultrastructural study of glial cells in the developing visual cortex of the rat.
It is suggested that the progression from light to medium oligodendrocytes does not simply represent a diminution in the overall level of synthetic activity but that different components of the myelin sheath are being synthesized at the two stages.
