Figure 4
A comparison of the average cortical porosity between the ventral and dorsal portions of LV4. (a, b) The average cortical porosity in ventral wall of LV4 is plotted against the administration frequency (A) and total amount of TPTD administered (μg·kg−1 per week; b). (c, d) The average cortical porosity in the dorsal wall of LV4 is plotted against the administration frequency (c) and total amount of TPTD administered (μg·kg−1 per week; d). (a, c) The data are shown as the means (n=4 or 5). Black closed circle: Sham control, opened circle: vehicle control, diamond: 1.2 μg·kg−1, triangle: 6 μg·kg−1, square: 30 μg·kg−1. (b, d) Data represent means (n=4 or 5). Black closed circle: Sham control. Blue: three times a day, green: two times a day, red: once a day, brown: three times a week. Opened circle: vehicle control, diamond: 1.2 μg·kg−1, triangle: 6 μg·kg−1, square: 30 μg·kg−1.
