Institution of a low-NaCl diet beginning at embryonic day 3 and continued throughout pre- and postnatal development has widespread effects on the neuroanatomical organization of the first gustatory relay in the nucleus of the solitary tract. To determine when these effects are expressed postnatally, the terminal field of the chorda tympani nerve was compared between sodium-restricted and sodium-replete rats at postnatal days 15–17, postnatal days 25–27, postnatal days 35–37, and adults. Total terminal fields were significantly larger in postnatal days 35–37 and adult sodium-restricted rats compared with aged-matched controls. The group-related differences appear related more to a remodeling of the …
