Fig. 1.

The effects of bilobalide on hippocampal synaptic transmission. Left Relative fEPSP slopes were plotted against the relative presynaptic volley slopes at SC-CA1 (a), MPP-DG (b), LPP-DG (c), and MF-CA3 (d) synapses. Linear regressions were calculated under each condition (solid line control conditions, dotted line bilobalide conditions). Inset The typical waveforms in the absence (left) and presence (right) of bilobalide. Scales 0.5 mV, 5 ms. Right Averaged minimal magnitude of the presynaptic fiber volley required to evoke the maximal fEPSP. *p < 0.05
