Method Scanning electron microscope (SEM) autoradiography
Comments "When autoradiograms were exposed for short periods (~6 h) to give a countable grain density over three endplates, [researchers] obtained an average site density of 20,817 sites/µm^2. This value is close to the average of 18,000 sites/µm^2 obtained by TEM [transmission electron microscope] autoradiography for both innervated and denervated sternomastoid muscles (Loring and Salpeter, 1980 Levitt-Gilmour and Salpeter, 1986)."
