Rats raised from weaning in a complex environment have an increased number of synapses per neuron in the visual cortex in comparison to animals housed in standard laboratory cages. Previous research has suggested that experience-dependent synaptic changes may be coordinated with changes in astrocytes. The present study used electron microscopy to examine astrocytic processes in the visual cortex of rats raised in a complex environment (EC) or in standard laboratory cages, either individually… 
Housing Complexity Alters GFAP-Immunoreactive Astrocyte Morphology in the Rat Dentate Gyrus
To assess morphological changes among astrocytes of the rat dentate gyrus, piSeeDB was used to optically clear 250 μm sections of tissue labeled using GFAP immunohistochemistry and image analysis were used to measureAstrocyte morphology, which demonstrated a reduced distance between filament branch points.
Synaptic potentiation induces increased glial coverage of excitatory synapses in CA1 hippocampus
Recon reconstructions of synapses reveal dynamic, activity‐dependent interactions between glial processes and pre‐ and postsynaptic partners and suggest that glia can participate in activity‐induced structural synapse remodeling.
Astrocyte-Synapse Structural Plasticity
The present review summarizes some of the findings on the mechanisms driving this form of structural plasticity and its possible impact on synaptic structure and function and focuses on the ability of astrocytes to rapidly restructure their processes and modify their coverage of the synaptic elements.
Cooperative Astrocyte and Dendritic Spine Dynamics at Hippocampal Excitatory Synapses
This work presents a system that can be used to characterize the intricate relationship between astrocytic processes and synaptic structures in situ using organotypic hippocampal slices, a preparation that retains the three-dimensional architecture ofAstrocyte–synapse interactions.
Three-Dimensional Relationships between Hippocampal Synapses and Astrocytes
Recent studies show that glutamate transporter-mediated currents occur in astrocytes when glutamate is released from hippocampal synapses. These transporters remove excess glutamate from the
Effects of Experience and Environment on the Developing and Mature Brain: Implications for Laboratory Animal Housing.
There is no conclusive evidence that enriched caging is essential or even that it increases well-being in laboratory rodents.
Environmental enrichment condition does not alter glutamine synthetase activity in the hippocampus and cerebral cortex of Swiss albino mice
The results showed that EE did not promote any significant change in GS activity in both regions tested, and future studies must focus on the temporal analyses of GS activity after EE conditions as well in other species and/or strains and during distinct age of life in order to understand the factors affecting the GS activity.
