A daily session consisted of four cycles, each preceded by a 10-min time out period in which all lights in the chamber were off and responding had no programmed consequences. Each cycle consisted of two components. The first component was signaled by red stimulus lights and consisted of a FR 18 schedule of food pellet delivery (Bioserve, Frenchtown, NJ, USA) followed by a 10-s time out. The second component, signaled by green stimulus lights, consisted of the FR 18 schedule of food delivery combined with a FR 20 schedule of foot shock delivery (1.5–3.0 mA, adjusted for each monkey based on individual performance, 0.25-s duration). Both components were 5 min in duration or ended after the monkey obtained five food pellets or received three foot shocks, whichever occurred first. Test sessions were conducted once or twice per week. Here, i.v. injections of vehicle or drug were administered in the fifth minute of each time out. In successive cycles, increasing doses of the test drug were administered using a cumulative dosing procedure. The dependent measure was the average rates of responding (responses/s), calculated by dividing responses by time during components 1 and 2, excluding responding during time outs or reinforcer delivery。 |

每日會話包括四個周期,每個前面有一個10分鐘的時間段進行,其中在室內(nèi)所有的燈都關(guān)閉,響應沒有編程的后果。每個循環(huán)由兩部分組成。第一個環(huán)節(jié)是由信號刺激的紅色燈光,包括了食物顆粒輸送幀中繼18日程 (浮游生物,弗倫奇敦,NJ,USA)接著是10秒超時。第二個組成部分,通過綠色燈光的刺激信號,包括送外賣的FR18日程 加上FR20附表腳電擊(1.5-3.0毫安,根據(jù)個人表現(xiàn),0.25秒持續(xù)時間中調(diào)整每只猴子)。這兩種成分是 5分鐘的時間或之后的猴子得到5食物顆;蚪邮盏娜阏鹗,以先發(fā)生的結(jié)束.測試環(huán)節(jié)進行,每周進行一次或兩次。在這里,靜脈注射車輛或藥物的注射劑施用在每次出的第五分鐘。在連續(xù)的周期, 增加劑量的試驗藥物用累積加藥過程管理。的相關(guān)措施是響應(響應/秒)的平均價格,通過在部件1和2分的回應時間,但不包括在超時或強化物交付響應計算。 |
