Periterminal synaptology of dorsal root glomerular terminals in the substantia gelatinosa of the spinal cord in the rhesus monkey

The synaptic glomerular complexes surrounding dorsal root terminals in the substantia gelatinosa were reconstructed from six sets of 50–140 gapless ultrathin serial sections prepared in the transverse plane of the spinal cord in adult rhesus monkeys. All three types of glomeruler terminals described in the preceding paper (Knyihar‐Csillik et al., 1982) were identified: (1) DSA (endings of superificial collaterals); (2) LDCV (endings of marginal collaterals); and (3) RSV (endings of deep collaterals). Each type of terminal forms a glomerular complex which invariably includes presynaptic dendrites which are intercalated between primary terminals and the postsynaptic (conventional) dendrite. Since the latter also receives direct input from the primary sensory terminal the synaptic organization assumes triadic arrangements, suggesting that primary afferent impulses my be subjected to a postsynaptic modulation through inhibitory action of presynaptic dendrites.
