Figure 4. Simultaneous monitoring of synaptic strength and presynaptic function during LTP.

Figure 4

A. Presynaptic function, as indicated by peak ΔF, was slowly enhanced during compound LTP induced by 200-Hz tetanization. B. NMDAR-LTP induced by 50-Hz tetanization resulted in a lack of presynaptic enhancement.
