在动物身上已经观察到了惊吓反应和惊吓反应的适应性(脉冲前抑制和习惯化)。本文报道了8个近交系小鼠品系的筛选,以确定遗传因素是否会影响这些行为。在对声惊吓的敏感度、听觉惊吓和触觉惊吓的大小以及触觉和听觉惊吓的脉冲前抑制(PPI)大小上都发现了品系差异。这两种惊吓反应和两种形式的PPI之间都没有显著的相关性,这表明不同的基因调控这两种形式的惊吓和PPI。然而,声学-声学PPI与海马区听觉门控(TC比率)显著相关,这表明调节这两种形式的感觉门控的基因存在重叠。
The startle response and adaptability of the startle response (prepulse inhibition and habituation) have been observed in animals. The studies reported here screened 8 inbred mouse strains to determine whether genetic factors influence these behaviors. Strain differences were found in both the sensitivity to acoustic startle and the magnitude of both the auditory and tactile startle as well as the magnitude of prepulse inhibition (PPI) of both tactile and acoustic startle. Neither the 2 startle responses nor the 2 forms of PPI were significantly correlated with one another, suggesting that different genes regulate these 2 forms of startle and PPI. Acoustic-acoustic PPI was significantly correlated, however, with hippocampal auditory gating (TC ratio) suggesting an overlap in the genes that regulate these 2 forms of sensory gating.
