Ugo basile Passive Avoidance - step through 被動迴避測試儀

產品型號: 40550
廠牌名稱:
Ugo Basile被動迴避測試儀(穿過法)主要用於進行經典的被動迴避實驗,高效可靠。新的電子觸控設備能夠操控包括8段電擊刺激器在內的各項部件。使用該觸控平板還可以操控所有的Ugo Basile實驗箱。
被動逃避實驗是用於評估動物的關聯記憶功能的實驗方法。利用大、小鼠會從明亮的區域逃往黑暗地方的習性。一個明亮的間隔是動物會逃避的環境,另外一個黑暗間隔中對動物進行負面刺激(如電刺激)。動物會逐漸減少或根本不進入黑暗位置,形成被動迴避。
Ugo Basile被動迴避系統包含一個控制主機、一個推拉式門分隔成明暗兩部分的實驗箱。實驗箱中傾斜的底板保證準確測定動物穿過明暗間隔時的運動,簡易可靠。

產品特點

  • 全套設備包含箱體及專用觸控平板系統,無需額外連接電腦
  • 使用靜音閘門,開啟關閉皆不會造成噪音進而影響動物表現
  • 獨家偵測技術,給您最準確的動物進出數據
  • 各項實驗參數皆可自行設定,給您最有彈性的操作空間

被動迴避實驗是用於評估動物的關聯記憶功能的實驗方法。利用大、小鼠會從明亮的區域逃往黑暗地方的習性。箱體其中一個區域為明亮的空間 (動物不喜歡),另外一個區域為動物偏好的暗房,在暗房對動物進行厭惡刺激(如電刺激)。動物會逐漸減少或根本不進入暗房,形成被動迴避。

The Passive Avoidance Set-Up (step-trough method) by Ugo Basile, is an efficient and reliable instrument for the classic Passive Avoidance Test. 

Multiple configurations can be controlled by the NEW  electronic with touch-screen, which encompsses a precision 8-pole shocker.

The P.A. set-up is part of UB conditioning-cage project; you buy a single touch-screen controller, and manage all UB cages. Ask for details!

 

Passive Avoidance Test is used to assess memory function based on the association formed between a specific environmental context, which the animal learns to avoid, and an aversive stimulus, represented by a mild foot shock. The tests are conducted in a two-compartment apparatus, where one is dimly lit and preferable to a rodent, and the other is brightly lit.

Ugo Basile Passive Avoidance set-up instrument basically consists of a Controller, and a Cage: a partition which embodies a sliding door divides the P.A. Cage into two compartments, one black and one white, brightly illuminated. The tilting floor ensures a simple and reliable detection mechanism to score the animal’s movement across the two compartments.The 40500-001 Programming/Recording Unit, encompasses all controls, incorporates a constant-current high precision 8-pole shocker, and manages data acquisition: data are stored insite the unit and can be downloaded via the USB key provided as standard, for further processing via Excel, Access, etc.

The Unit, which incorporates a 12” touch-screen, manages both Passive and Active Avoidance Tests. Up to 4 cages can be connected to the same Controller. If more than one cage is connected, an expansion box 40500-005 is required for each additional cage. 

Remote Control feature will make remote service and software upgrades extremely simple!

應用領域

Behavioral scientists are well acquainted with passive avoidance methods that have been used for several decades, originally by psychologists, who were interested in animal behavior.

These procedures were later exploited by neuroscientists, who specifically perform sys-tematic studies of the behavioral changes mainly produced by brain lesions, to define the functions of different C.N.S. sections.

The Passive Avoidance was soon extended to several other areas of research such as behavior genetics, psychopharmacology and behavioral toxicology. More recently, such use has become routine in animal model studies of aging and of Alzheimer-type demen-tia, including the search for new drugs of potential therapeutic value, consisting of atten-uation of behavioral deficits.

The Passive Avoidance task is a one trial fear-motivated avoidance task, classically used to assess short-term or long-term memory on small laboratory animals (rodents).
