Ultrastructural study of glutamate- and GABA-immunoreactive terminals contacting the primary afferent fibers in frog spinal cord: A double postembedding immunocytochemical study

The in vitro HRP application to the dorsal root of the frog spinal cord produced an intensive staining of primary afferent fibers. A double postembedding GABA and glutamate immunocytochemical study revealed GABA- or glutamate-immunopositive presynaptic boutons establishing axo-axonic synapses onto H...

Description
Summary:The in vitro HRP application to the dorsal root of the frog spinal cord produced an intensive staining of primary afferent fibers. A double postembedding GABA and glutamate immunocytochemical study revealed GABA- or glutamate-immunopositive presynaptic boutons establishing axo-axonic synapses onto HRP-stained primary afferent fibers in the spinal cord intermedial zone.
