In contrast, the four mice with high dorsal c-fos+ cell density also had high ventral c fos+ cell density, and the correlation between dorsal and ventral c-fos expression was highly significant (r2 = 0.75, slope 0.101, F= 18.1, p = 0.005), suggesting that c-fos expression increase somewhat uniformly across the hippocampus in a subset of mice after PTZ.
