The peripheral taste system likely maintains a specific relationship between ganglion cells that signal a particular taste quality and taste bud cells responsive to that quality. We have explored a measure of the receptoneural relationship in the mouse. By injecting single fungiform taste buds with lipophilic retrograde neuroanatomical markers, the number of labeled geniculate ganglion cells in...

A monoclonal antibody, RA4, was developed that recognizes retinal ganglion cell axons in the mature retina. Between embryonic days 3 and 9, the RA4 antigen was associated with cell bodies in certain regions of the retina in addition to the ganglion cell axons. The RA4-positive cells were of 3 types: an apolar cell adjacent to the ventricular surface, a bipolar cell that spanned the thickness of...

The development of superior cervical ganglion cells has been studied in the fetal rat. Sympathetic cells appear first in thoracic sites and, one day later, in cervical sites; localized proliferation among these cells gives rise to the superior cervical and stellate ganglia. The maturation of superior cervical ganglion cells was examined by staining these neurons with horseradish peroxidase in f...

The rodent trigeminal system is characterized by the punctate organization of its afferents and neurons that replicate the distribution of mystacial vibrissae and sinus hairs on the snout. We have examined the development of topographic equivalence between the sensory periphery on the snout and the brainstem trigeminal nuclei in rats. Lipophilic tracers Dil (1,1'-dioctodecyl-3,3,3',3'-tetrameth...

The retina acts as the primary stage for encoding of visual stimuli in central nervous system. It is comprised numerous functionally distinct cells tuned to particular types stimuli. This work presents an analytical approach identifying contrast-driven retinal cells. Machine learning approaches well traditional regression models are used represent input-output behaviour ganglion findings this d...
