Performance by the Wt and Tg rats on the accelerating rotarod. *, ** p< 0.05 and 0.01, respectively, when compared against wild-type animals with normal diet; †, †† p< 0.05 and 0.01, respectively, when compared against wild-type animals with vitamin A-deficient diet.

Vertical and rearing activity for the HIV-1 transgenic (Tg) and wild type (Wt) rats on the normal (VA+) or vitamin A deficient (VA−) diet. *, ** p< 0.05 and 0.01, respectively, when compared against wild-type animals with normal diet; †, †† p< 0.05 and 0.01, respectively, when compared against wild-type animals with vitamin A-deficient diet.

Horizontal activity and total distance measurements for the HIV-1 transgenic (Tg) and the wild type (Wt) rats on the normal (VA+) or vitamin A deficient (VA−) diet. ** p< 0.01, respectively, when compared against wild-type animals with normal diet; †† p< 0.01, respectively, when compared against wild-type animals with vitamin A-deficient diet.

Rotarod performance for the Wt and Tg rats on the VA+ and VA− diets during training and at increasing rod speeds. At 12 rpm all of the Wt rats on the normal diet remained on the rotarod for the maximum time allowed (180 sec.). *, ** p< 0.05 and 0.01, respectively, when compared against wild-type animals with normal diet; †, †† p< 0.05 and 0.01, respectively, when compared against wild-type animals with vitamin A-deficient diet.
