SCG postnatal remodelling - hypertrophy and neuron number stability - in Spix's Yellow-toothed Cavies (Galea spixii)

► A 77% increase in ganglion volume. ► Stability in the total number of the whole population of SCG nerve cells. ► A higher proportion of uninucleate neurons to binucleate neurons only in newborn animals. ► A 130% increase in the volume of uninucleate neurons. ► The presence of Brd-U positive neurons in animals at all ages.
