WebbActivation of the slow EPSP requires the presence of a conditioning substance (presumably glycine) that is actively re- leased into the extracellular medium, perhaps by glial cells. It seems likely that the interplay between these 2 modulators could significantly alter synaptic efficacy at synapses in the hippocam- pus.
