Neuronal-Astrocytic Interactions in Brain Development, Brain Function and Brain Disease

  • Leif Hertz
Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 296)

Abstract

The purpose of this review is to discuss neuronal-astrocytic interactions which appear to be of major importance in development and function of the brain as well as in brain disease. Initially, the role of these interactions during development will be reviewed followed by a description of their role in normal brain function; finally, the possible importance of a breakdown of these interactions during disease processes will be discussed. However, before starting the description of these interactions, some of the current knowledge of astrocytic functions will be briefly reviewed.
