The interplay between neurons and glia in synapse
... Jeff A Stogsdill and Cagla Eroglu In the brain, the formation of complex neuronal networks amenable to experience-dependent remodeling is complicated by the diversity of neurons and synapse types. The establishment of a functional brain depends not only on neurons, but also non-neuronal glial cells. ...
