Marking PSD region for measurements. The PSD region is first outlined by the postsynaptic membrane, the edges of which were marked by two small black arrows in a and b. Two vertical lines were then drawn from the edges of the postsynaptic membrane 120 nm deep into the cytoplasm. A dashed black line parallel to the postsynaptic membrane was then drawn to enclose the PSD region for measurement. The distances of particles to postsynaptic membrane were marked by the white double-headed arrows. Sample on left (a) was treated with control media, and sample on right (b) was treated with 50 μM of NMDA for 2 min. Scale bar = 100 nm
