  • 論文摘要

    本研究旨在探討側中膈和內中膈在大白鼠活動量、反應性和開放式場地等行為量數方面,所扮演的角色。因此本實驗乃分別破壞大白鼠的側中膈、內中膈和聯合破壞側、內中膈,以研究這些處理所造成的行為效果。

    本研究結果發現,破壞大白鼠的側中膈會顯著地減少其Iocomotor活動,其rearing次數似乎也減少了;此外,還顯著增加了大白鼠在活動箱中的移動時間、刻板化行為和驚嚇箱中的驚嚇反應。而內中膈破壞的主要效果,在於顯著地減少大白鼠在開放式場地中央區域的活動和探索行為。就大多數的行為量數而言,聯合破壞組的效果與單獨破壞內中膈頗為相似,但是在驚嚇反應上,聯合破壞則會加大大白鼠的驚嚇反應強度,而內中膈破壞却毫無影響;若比較反應型式,聯合破壞也與側中膈破壞有別。

    最後,我們還從中膈的解剖、神經化學和藥理機制上的不同,來討論上述結果的意義。
