Behavioral outcomes in cocaine self-administration. A) Both Mild and Severe animals took more infusions overall (p < 0.001, p = 0.003, respectively). B) Increased active lever presses were also observed in Mild and Severe animals relative to Sham (p’s < 0.001). C) Severe TBI animals pressed the inactive lever more than Shams (p < 0.001). D) Severe TBI animals also showed weaker discrimination of the active lever relative to Sham (p < 0.001). E) Severe TBI animals were also worse at discriminating the cue that signaled cocaine availability (p < 0.001). *** = p < 0.001; ** = p < 0.01.
