nervous system
• significant decrease in the magnitude of LTP induced by 200 Hz tetanic stimulation, such that the mean field EPSP measured 1 hour after induction of LTP is enhanced to only 145% of its pretetanus level in mutants compared to 198% enhancement in controls
• the enhancement of FM 1-43 (a fluorescent marker of synaptic vesicle cycling) release from presynaptic terminals seen in controls during high-frequency (200 Hz) tetanic stimulation is blocked in mutants; rate of FM 1-43 release during low-frequency (50 Hz) tetanic stimulation is normal
• mutants exhibit a smaller magnitude of LTP 1 hour following theta burst stimulation, with an enhancement in the fEPSP to 136.7% of it's initial value compared to 166% in controls
