In small synapses (200 nm × 200 nm), Ratios of maximum NMDA receptor opening probabilities as functions of receptor distance for different release speed (slow, 2 nm fusion pore—triangle, regular, 10 nm fusion pore—asterisk, and instantaneous—circle) of glutamate vesicle release. The open probabilities were calculated by the kinetics equation, when glutamates are released above the center location
