Motivation remains intact in tumor bearing mice. A, nosepoke and
breakpoint performance during training for the PR task. B, PR
performance is decreased 24 and 48 h after LPS (0.5 mg/kg) injection compared to
PBS (n=8/group). C, tumor bearing mice (n=10)
exhibit no decrease in PR performance compared to CTL (n=6). *,
