Here are some of our more labs more recent glial plasticity papers, this 
should provide a reasonably good start:

Hawrylak, H. and Greenough, W.T. (1995). Monocular deprivation alters 
the morphology of glial fibrillary acidic protein-immunoreacitive 
astrocytes in the rat visual cortex. Brain Research, 683, 187-199.

Jones, T.A., Hawrylak, N., and Greenough, W.T. Rapid changes in GFAP 
immunoreactive astrocytes in rats reared in a complex environment. 
Psychoneuroendocrinology, in press. 

Jones, T.A. and Greenough, W.T. Ultrastructural evidence for increased 
contact between astrocytes and synapses in rats reared in a complex 
environment. Neurobiology of Learning and Memory, 65, 48-56.

Anderson, B.J., Li, X., Alcantara, A.A., Isaacs, K.R., Black, J.E. and 
Greenough, W.T. Glial hypertrophy is associated with synaptogenesis 
following motor-skill learning, but not with angiogenesis following 
exercise. GLIA, 11:73-80, 1994. 

Chang, F.-L., Hawrylak, N. and Greenough, W.T.  Astrocytic and synaptic 
response to kndling in hippocampal subfield CA1. I. Synaptogenesis in 
response to kindling in vitro. Brain Research, 603, 302-308.

Hawrylak, N., Chang, F.-L. and Greenough, W.T. Astrocytic and synaptic 
respnse to kindling in hippocampal subfield CA1. II. Synaptogenesis and 
astrocytic process increases to in vivo kindling. Brain Research 603, 

Sirevaag, A.M. and Greenough, W.T. Plasticity of GFAP-immunoreactive 
astrocyte size and number in visual cortex of rats reared in complex 
environments. Brain Research, 540, 273-278.

I hope this helps,
