Figure 4. Percent Responding on Cocaine Lever Following Pentobarbital.

Figure 4

Developmental exposure to 3 and 6 mg/kg/day PCBs did not alter the percentage of responding on the cocaine lever following administration of 5.0 mg/kg pentobarbital (IP). Much less responding occurred on the cocaine-paired lever following the test dose of pentobarbital relative to test doses of cocaine and amphetamine.
