Geniculate Neuralgia and Facial Nerve Sensory Systems

Recurrent facial taste neurons of sea catfish Plotosusjaponicus: morphology and organization in the ganglion

“…A bifurcation of the single process originating from each soma of taste neurons in the ganglia occurs in various species of mammals, such as M . musculus (Boudreau et al ., 1977), guinea pig Cavia porcellus and monkey Macaca irus (Kitamura et al ., 1982). Nagai & Matshushima (1990) successfully labelled cell bodies and their single processes in the glossopharyngealvagal ganglia of A. mexicanum with the cobaltic lysine method.…”

Differential Expression of Capsaicin-, Menthol-, and Mustard Oil-Sensitive Receptors in Naive Rat Geniculate Ganglion Neurons

“…The GG neurons also project within the somatosensory nerve, which innervates the skin at the inner surface of the ear pinna via the posterior auricular nerve and causes neuralgia (Boudreau et al, 1977). The percentage of the population in the GG neurons is still unknown.…”

Physiology of Taste Processing in the Tongue, Gut, and Brain

“…The mouse GG contains around 1000 neurons with 42% innervating TRCs (i.e., 27% from the CT and 15% from the GSP) and 58% somatosensory fibers that innervate the outer ear (25,64,193,218). GG neurons can be genetically labeled by the expression of the transcription factors Phox2b + (Figure 8A), which is involved in the differentiation of "gustatory neurons" and Phox2b − that is involved in the differentiation of "somatosensory neurons" innervating the outer ear (47).…”
