Fig. 188.8.131.52. Graphic reconstruction (i.e. manually shaded serial contour tracings) of dendritic spines arising from three dendrites (D1, D2, D3) participating in synaptic glomerule in thalamic ventrobasal nucleus. Some of spines are branched (asterisk). Multiple macular synapses of different afferent origin are marked in blue, red and yellow. Extensive reticular adherent zones free of synaptic vesicles are marked in green. (Rat, thalamic ventrobasal nucleus.)
