Sal–sal mice obtained saline both of those all through growth and expression of behavioral sensitization; sal–coc mice gained saline all through development and cocaine for the expression of behavioral sensitization; coc–sal mice obtained cocaine during advancement and saline for the expression of behavioral sensitization; coc–coc mice received cocaine each for the duration of progress and expression of behavioral sensitization.
