The strength of an excitatory synapse depends on its ability to release glutamate and on the density of

synaptic transmission at the level of cleft glutamate to investigate properties of the release machinery in

investigating synaptic release during 100 Hz trains. Here we describe the detailed procedures for design

hippocampal cultures, and imaging of evoked glutamate transients with two-photon laser scanning

localize the vesicle fusion site with a precision exceeding the optical resolution of the microscope. By

iGluSnFR transients. The typical time frame for these experiments is 30 min per synapse.
