The peripheral astrocyte process (PAP) preferentially associates with the synapse. The PAP, which is not found around every synapse, extends to or withdraws from it in an activity-dependent manner. Although the pre- and postsynaptic elements have been described in great molecular detail, relatively little is known about the PAP because of its difficult(More)
Amongst several forms of glia-neuronal communication, glia-synaptic interaction appears particularly interesting in the light of the well-known examples of two-way signaling between neurons and astrocytes. We review recent structural and physiological evidence showing that the structural correlate of glia-synaptic interaction is the peripheral astrocyte(More)
