Mechanisms of glial retraction in the hypothalamo-neurohypophysial system of the rat.
It has been known for more than twenty years that changes in glial coverage of magnocellular neurones in the hypothalamo-neurohypophysial system accompany activation of those neurones. This led to the so-called 'glial retraction hypothesis.' However, until recently, little has been established as to how this structural plasticity of astrocytes develops. This paper will explore a number of hypotheses and supporting data concerning these changes.
