Evaluation of different methods by using a morphology-based equivalent electrical model revealed that quantitative capacitance measurements are possible in this presynaptic structure. Voltage pulses leading to presynaptic Ca2+ inflow evoked large capacitance signals that showed saturation with increasing pulse duration. The mean peak capacitance increase was 100 fF, corresponding to a pool of approximately 1,400 releasable vesicles. Thus hippocampal mossy fiber synapses have a vesicular &quot;maxipool.&quot; Large pool size and rapid vesicle recycling may underlie the uniquely large extent of activity-dependent plasticity in this synapse."}],"author":[{"last_name":"Hallermann","full_name":"Hallermann, Stefan","first_name":"Stefan"},{"last_name":"Pawlu","first_name":"Christian","full_name":"Pawlu, Christian"},{"last_name":"Jonas","id":"353C1B58-F248-11E8-B48F-1D18A9856A87","full_name":"Peter Jonas","first_name":"Peter M","orcid":"0000-0001-5001-4804"},{"first_name":"Manfred","full_name":"Heckmann, Manfred","last_name":"Heckmann"}],"doi":"10.1073/pnas.1432836100","_id":"3806","title":"A large pool of releasable vesicles in a cortical glutamatergic synapse","quality_controlled":0,"citation":{"ieee":"S.
