Learned Helplessness I+II-TSE習(xí)得無助I+II

Learned Helplessness I+II   習(xí)得無助I+II

Learned Helplessness （LHN） is a well-known behavioral paradigm to study depression-like behavior and anti-depressant drugs in animals. Unpredictable, inescapable foot shock exposure of animals induces response deficits in a subsequent escape learning task.
習(xí)得性無助（LHN）是一種*的行為學(xué)范例，用于研究動(dòng)物抑郁類行為和抗抑郁藥物。動(dòng)物暴露在不可預(yù)知的，不可避免的適度的腳部電擊中，會(huì)導(dǎo)致接下來的逃離學(xué)習(xí)任務(wù)中反應(yīng)缺乏。

TSE Systems offers three different approaches to studying LHN.In the system based on an Operant Behavior （Skinner box） apparatus the animal can escape the shock during the test session by pressing a lever.The fully automated LHN test is controlled by the multi-purpose Operant Behavior software that provides predefined paradigms for pre-exposure and test. A free-programming language is available for generating custom procedures.
TSE提供了三種不同的方法來研究習(xí)得性無助。基于一個(gè)操作行為（斯金納箱）設(shè)備的系統(tǒng)中，在測試期間動(dòng)物可以通過按操作桿終止電擊。全自動(dòng)的LHN測試通過多功能操作行為軟件進(jìn)行控制，軟件提供預(yù)定義的范例，用于預(yù)暴露和測試。一個(gè)自由編程的魚宴可用于生成自定義的程序。

The alternative approach to study LHN in mice & rats is based on the Active Avoidance task, which is also part of the new Multi Conditioning System.
研究小鼠和大鼠LHN的另一種選擇，是基于主動(dòng)回避任務(wù)，亦是我們新的多條件系統(tǒng)的組成部分。
• Helplessness test based on operant response （lever pressing） or active avoidance
