Figure 1. Persistent synaptic activity evoked by multiple PP stimuli.

Figure 1

a, Experimental configuration. A four-position stimulating electrode was used to activate different PP segments while recording synaptic input in hilar neurons. b, Example of a hilar mossy cell synaptic barrage evoked by PP stimulation (arrow heads). The timing of the onsets of individual EPSPs is indicated by vertical lines. Enlargement of region indicated with horizontal bar shown in inset. c, Experimental protocol and EPSP analysis windows. d, Responses to three repetitions of each of the four stimulus positions (A-D) in one hilar mossy cell. Vertical lines indicate EPSP onset times. Mean EPSP frequency and range for each stimulus type indicated on right. Diagram of experiment protocol shown at top.
