Accepted model for brain signaling flawed

Accepted model for brain signaling flawed @ ScienceDaily

A new study out January 10 in the journal Science turns two decades of understanding about how brain cells communicate on its head. The study demonstrates that the tripartite synapse -- a model long accepted by the scientific community and one in which multiple cells collaborate to move signals in the central nervous system -- does not exist in the adult brain.
