Fig 7. Percentage of open AMPA receptors at different positions of the PSD.

Fig 7

Panels a to d represent the PSD of a model synapse at different time points after a single vesicle of glutamate is released at the center of the synapse. The PSD has a total side length of 385 nm; it has been divided into cells with a side length of 55 nm and the percentage of open AMPA receptors within each cell has been represented by a color scale. Time points correspond to an early stage after glutamate release (a), the peak of open AMPA receptors (b), a time point after the peak (c) and a late stage when open receptors are scarce or absent (d). Although open receptors are preferentially located near the release point, all receptors, including the most peripheral ones, contribute to the synaptic response.
