title: Effects of d-amphetamine, maprotiline, L-dopa, and haloperidol on the components of the predatory behavior of the ferret, Putorius furo L.
abstract: Ferret predation on rats was examined in an arena. One hour before the test one of the following drugs was administered. d-Amphetamine (0.8 and 1.4 mg/kg IM), MAPROTILINE (10 AND 40 Mg/kg orally), L-dopa (30 and 60 mg/kg orally), or haloperidol (0.14 and 0.6 mg/kg IM). Provided that capture was successful, the sequence of the behavioral components was not changed by these drugs. With the exceptions of paw movements and rolling over, which were not affected by the drugs, the components of predatory behavior were influenced differently. This leads to the assumption that a drug affects different mechanisms which control behavior. It is assumed that dopamine is involved in the control of capture elicitation as well as in the control of pursuit and biting. Capture elicitation was inhibited by d-amphetamine and L-dopa, but not by maprotiline, and was even facilitated by haloperidol. The orientation of pursuit movements and biting was impaired by L-dopa and improved by haloperidol, whereas maprotiline did not influence these components.
