Environmental modulation of cocaine self-administration in the rat

Rationale Previous studies have shown that environmental context can powerfully modulate the induction of psychomotor sensitization to cocaine in the rat.

520			\|a Rationale Previous studies have shown that environmental context can powerfully modulate the induction of psychomotor sensitization to cocaine in the rat. Rats that receive repeated administrations of cocaine in association with environmental novelty exhibit greater psychomotor sensitization than animals that receive the same treatments in their home cages. Objectives The goal of the present study was to investigate whether environmental context can exert its modulatory influence also on cocaine self-administration. Materials and methods Independent groups of rats with intravenous catheters were given the possibility to self-administer different doses of cocaine (0.0, 0.2, 0.4, and 0.8 mg/kg per infusion) under two environmental conditions. Some animals were housed in the self-administration cages (home groups), whereas other rats were transported to the self-administration cages only for the test sessions (novelty groups). Results Environmental “novelty” facilitated the acquisition of cocaine self-administration at the doses of 0.2 and 0.4 mg/kg per infusion. When rats were given access to a higher dose of cocaine (0.8 mg/kg per infusion), there were no significant group differences in drug taking. Environmental context had no effect on the self-administration of the vehicle. Thus, it appears that environmental “novelty” produced a shift to the left in the dose-effect curve for cocaine self-administration. Furthermore, “novelty” enhanced the motivation of the rats to work for cocaine, as indicated by the results of a progressive ratio procedure. Conclusions The present findings demonstrate for the first time that the environment surrounding drug taking can alter both the intake of and motivation for cocaine.

Rats that receive repeated administrations of cocaine in association with environmental novelty exhibit greater psychomotor sensitization than animals that receive the same treatments in their home cages. Objectives The goal of the present study was to investigate whether environmental context can exert its modulatory influence also on cocaine self-administration. Materials and methods Independent groups of rats with intravenous catheters were given the possibility to self-administer different doses of cocaine (0.0, 0.2, 0.4, and 0.8 mg/kg per infusion) under two environmental conditions. Some animals were housed in the self-administration cages (home groups), whereas other rats were transported to the self-administration cages only for the test sessions (novelty groups). Results Environmental “novelty” facilitated the acquisition of cocaine self-administration at the doses of 0.2 and 0.4 mg/kg per infusion. When rats were given access to a higher dose of cocaine (0.8 mg/kg per infusion), there were no significant group differences in drug taking. Environmental context had no effect on the self-administration of the vehicle. Thus, it appears that environmental “novelty” produced a shift to the left in the dose-effect curve for cocaine self-administration. Furthermore, “novelty” enhanced the motivation of the rats to work for cocaine, as indicated by the results of a progressive ratio procedure.

Rats that receive repeated administrations of cocaine in association with environmental novelty exhibit greater psychomotor sensitization than animals that receive the same treatments in their home cages. Objectives The goal of the present study was to investigate whether environmental context can exert its modulatory influence also on cocaine self-administration. Materials and methods Independent groups of rats with intravenous catheters were given the possibility to self-administer different doses of cocaine (0.0, 0.2, 0.4, and 0.8 mg/kg per infusion) under two environmental conditions. Some animals were housed in the self-administration cages (home groups), whereas other rats were transported to the self-administration cages only for the test sessions (novelty groups). Results Environmental “novelty” facilitated the acquisition of cocaine self-administration at the doses of 0.2 and 0.4 mg/kg per infusion. When rats were given access to a higher dose of cocaine (0.8 mg/kg per infusion), there were no significant group differences in drug taking. Environmental context had no effect on the self-administration of the vehicle. Thus, it appears that environmental “novelty” produced a shift to the left in the dose-effect curve for cocaine self-administration. Furthermore, “novelty” enhanced the motivation of the rats to work for cocaine, as indicated by the results of a progressive ratio procedure. Conclusions The present findings demonstrate for the first time that the environment surrounding drug taking can alter both the intake of and motivation for cocaine.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Self-administration</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Cocaine</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sensitization</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Environmental</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Addiction</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Paolone, Giovanna</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Celentano, Michele</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Testa, Arianna</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Nencini, Paolo</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Badiani, Aldo</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Psychopharmacology</subfield><subfield code="d">Berlin : Springer, 1959</subfield><subfield code="g">192(2007), 3 vom: 13.

abstract	Rationale Previous studies have shown that environmental context can powerfully modulate the induction of psychomotor sensitization to cocaine in the rat. Rats that receive repeated administrations of cocaine in association with environmental novelty exhibit greater psychomotor sensitization than animals that receive the same treatments in their home cages. Objectives The goal of the present study was to investigate whether environmental context can exert its modulatory influence also on cocaine self-administration. Materials and methods Independent groups of rats with intravenous catheters were given the possibility to self-administer different doses of cocaine (0.0, 0.2, 0.4, and 0.8 mg/kg per infusion) under two environmental conditions. Some animals were housed in the self-administration cages (home groups), whereas other rats were transported to the self-administration cages only for the test sessions (novelty groups). Results Environmental “novelty” facilitated the acquisition of cocaine self-administration at the doses of 0.2 and 0.4 mg/kg per infusion. When rats were given access to a higher dose of cocaine (0.8 mg/kg per infusion), there were no significant group differences in drug taking. Environmental context had no effect on the self-administration of the vehicle. Thus, it appears that environmental “novelty” produced a shift to the left in the dose-effect curve for cocaine self-administration. Furthermore, “novelty” enhanced the motivation of the rats to work for cocaine, as indicated by the results of a progressive ratio procedure. Conclusions The present findings demonstrate for the first time that the environment surrounding drug taking can alter both the intake of and motivation for cocaine. © Springer-Verlag 2007
