The majority of cells of the geniculate ganglion are gustatory, contributing to the chorda tympani and greater superficial petrosal nerves (Foley and DuBois, 1943; van Buskirk, 1945) innervating, respectively, fungiform papillae and palatal taste fields.

GFP immunoreactivity was detected in a subset of geniculate ganglion neurons (169/682, 24.8 %; Fig. 2B, C), whereas the P2X3 signal was present in nearly all ganglion cells (664/682, 97.4 %; Fig. 2B, C).

Interestingly, when nonbarbiturate anesthetics are used, a concentration - dependent increase in sideband excitation is observed in a subset of geniculate ganglion neurons (Wu et al., 2015).

Somatosensory innervation of these taste fields arises from the trigeminal nerve; therefore, cells of the geniculate ganglion that innervate taste fields are gustatory rather than somatosensory in function.

Our data demonstrate that a subset of geniculate ganglion neurons expresses 5 - HT3 receptors and innervates taste buds, including serotonergic type III cells.

A, Confocal Z - projection of 10 0.7 μm optical slices of geniculate ganglion from a 5 - HT3AGFP mouse showing expression of GFP (green) and P2X3 (magenta).

Searching for answers, Shatz decided to focus on the lateral geniculate nucleus (LGN), a clump of tissue shaped like a piece of elbow macaroni, set behind each eyeball, that serves as a relay station shunting visual signals to the ocular dominance columns.

The anterograde (forward) tracing results of retinal projections in the garden warbler demonstrated virtually identical connections between the eye and the brain as known from other lateral - eyed bird species [e.g. 15]--[18]: fibers either projected onto the contralateral optic tectum (part of the tectofugal system), to the nucleus of the basal optic root (part of the accessory pathway)(data not shown) or curved into the thalamus innervating the dorsal geniculate complex (Gld, for details, see Fig. 1C, 2A, D).
