April 1987 in “Brain Research” This study suggests that hair-follicle afferent axons can be presynaptically inhibited by boutons containing the enzyme glutamic acid decarboxylase, which is linked to the synthesis of γ-aminobutyric acid.

April 1990 in “Journal of comparative neurology” This study found that the spinal projection of afferents innervating slowly adapting mechanoreceptors had a greater rostrocaudal extent and number of boutons compared to those innervating rapidly adapting mechanoreceptors.

September 2002 in “The Journal of Comparative Neurology” This study found that in the dorsal horn's lamina III, most afferent boutons form synapses with presynaptic boutons immunoreactive for GABA and/or glycine, influencing sensory pathways.

September 2002 in “The Journal of Comparative Neurology” This study found that presynaptic inhibition of Aαβ cutaneous primary afferents in cats is mostly mediated by GABAergic interneurons that also contain glycine.
