Densities of Dentate Gyrus Neurons in PPA due to Tauopathies. Box and whisker plots show densities of granule (a), hilar (b), and total (c) neurons in the dentate gyrus of PPA-PiD (N = 8), -CBD (N = 8), -PSP (N = 8), and -AD (N = 8) cases. PSP cases showed a significantly higher density of granule neurons compare to PiD and CBD (p < 0.05), and AD cases demonstrated a significantly higher density of granule neurons than CBD cases (p < 0.05). Total neuronal density was generally equal across all tauopathies. Whiskers indicate minimum and maximum densities, and the box delineates lower and upper quartiles. Each point represents the neuronal density of an individual case. Line within the box represents median
