They hooked a potential receptor, serotonin 3, to green fluorescent protein and showed that the nerve terminals in the mouse tongue have serotonin 3 receptors, and these receptors are made by the nerve cells located in the geniculate ganglion.

At lower levels, in the retina and in the geniculate, cells in these two subdivisions differ in their color selectivity, contrast sensitivity, temporal properties, and spatial resolution.

When they tracked the cells» axons from the eye into the brain, they saw that many of them terminated in the lateral geniculate nucleus (LGN), the first relay station in the brain for visual information.

Specifically, they have found evidence of processing in the human lateral geniculate nucleus (LGN), a small node in the thalamus in the middle of the brain that relays nerve impulses from the retina to the primary visual cortex.

In situ hybridization on sections of gustatory ganglia (geniculate, petrosal / nodose) and a somatosensory ganglion (trigeminal) were performed to reveal serotonin receptor gene expression at the cellular level.

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.

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).

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).
