Figure 2.

Taste bud and geniculate ganglion numbers were maintained, but neurons were smaller after Bdnf gene removal during adulthood. A, Geniculate ganglion neuron number and (B) taste bud number were unchanged 4 and 10 weeks after tamoxifen (Tam) administration. C, We measured the diameters of 100 neurons per animal from images taken of each ganglion. Histograms show the distributions of neuron sizes, with the median indicated (red arrow). We also averaged these values in each animal (n = 3) and compared the means of these data points using an ANOVA. Means and standard errors are also shown on the Figure. Scale bar, 10 µm.
