 Da un certo punto di vista Astrocyte e' come un Neurone, mette a disposizione Astrosynapse, che con Presynapse e Postynapse creano la Synapse. Ma la synapse e' un concetto che verifichiamo quando c'e' il bind fra astrosynapse, presynapse e postsynapse. 
 
 A single astrocyte has a highly branched structure with thousands of fine processes, each wrapping around a different synapse. A human cortical astrocyte can contact anywhere from 100,000 to 2 million synapses simultaneously. So the question of selectivity is real and important.
