The testing apparatus was an open field in which 16 holes were made in the floor. Locomotion was measured by movement in the open field. Exploration was measured by investigation of the holes in the floor. In the first experiment the effects of apomorphine and ET 495 at three dose levels were compared in male rats that had been adapted to the testing situation for 21 days. In these animals, both drugs reduced exploration but only apomorphine reduced locomotion. In the second experiment, male and female rats with little prior experience in the apparatus were tested under three doses of apomorphine. In general the females were more sensitive to the drug, showing decreases in exploration at lower doses than did the males. Furthermore, the apomorphine failed to reduce locomotor activity in either sex except under the highest dose of apomorphine used (10 mg/kg) at which time stereotyped behavior was frequently observed.</p></div>","PeriodicalId":75577,"journal":{"name":"Behavioral biology","volume":"23 2","pages":"Pages 163-179"},"PeriodicalIF":0.0,"publicationDate":"1978-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0091-6773(78)91750-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11251084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Control animals of each strain were handled in the same manner but were never shocked. Blood samples were obtained from each rat on the fifth day via a chronic, indwelling tail arterial catheter. Previous exposure to footshock had no effect on plasma levels of norepinephrine (NE) and epinephrine (EPI) while animals were undisturbed in their home cages. After transfer to the shock chamber, the increases in plasma levels of NE and EPI were greater in previously shocked SHR than in unshocked SHR or shocked WKY rats. In addition, the increase in heart rate associated with transfer to the shock chamber was greater in previously shocked SHR rats than in unshocked SHR or in WKY controls. Previously shocked animals of both strains were also less active and defecated more frequently than controls when placed into the shock chamber. These results indicate that SHR and WKY rats have similar behavior responses to anticipation of footshock, but only in SHR rats is this attended by enhanced adrenergic responsivity.</p></div>","PeriodicalId":75577,"journal":{"name":"Behavioral biology","volume":"23 2","pages":"Pages 180-188"},"PeriodicalIF":0.0,"publicationDate":"1978-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0091-6773(78)91766-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11770097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
