高架十字迷宮(Elevated Plus-maze,EPM)實(shí)驗(yàn)是非條件反射模型,以動(dòng)物自發(fā)的恐懼樣反應(yīng)為行為學(xué)基礎(chǔ)。它既可以建立焦慮應(yīng)激的模型,也是國際上公認(rèn)的經(jīng)典測量焦慮反應(yīng)的方法。由Handley等在Montgonmery的研究基礎(chǔ)上發(fā)展而來,已被廣泛應(yīng)用于大鼠和小鼠等嚙齒類動(dòng)物焦慮行為學(xué)的研究。高架十字迷宮實(shí)驗(yàn)是利用動(dòng)物對(duì)新環(huán)境的探究和對(duì)高懸開放臂的恐懼而形成的矛盾沖突狀態(tài),通過觀察并記錄動(dòng)物進(jìn)入開放臂時(shí)間百分比和次數(shù)百分比來反映動(dòng)物的焦慮狀態(tài)。
Gene&I 在十多年的研究與服務(wù)過程中,積累了豐富的經(jīng)驗(yàn),并不斷改進(jìn)產(chǎn)品設(shè)計(jì)與用戶體驗(yàn),積極探索行為學(xué)的新發(fā)展方向!
Gene&I提供的高架十字迷宮分析系統(tǒng),不僅僅可以分析動(dòng)物在不同臂的拜訪次數(shù)停留時(shí)間、運(yùn)動(dòng)路程、潛伏期等常規(guī)參數(shù),還可以通過動(dòng)物身體的百分比,嚴(yán)格定義動(dòng)物是是否進(jìn)入了某一臂,或者出于中央?yún)^(qū),以及在臂體前的探究行為,實(shí)現(xiàn)試驗(yàn)的精確測量。3D分析功能可準(zhǔn)確判斷動(dòng)物在開放臂上的探究行為,提供了更精確的試驗(yàn)參數(shù)。
