[Abstract]  Most organisms react innately to the sudden onset of environmental stimulation. Audiogenic or loud noise in rodents provides an effective threatening signal to study the central nervous circuits responsible for the elaboration of various responses typically elicited by threatening/stressful environmental stimulation. Audiogenic stress offers many advantages over other environmental stimulation, including exquisite control over timing, intensity, and frequency, using off-the-shelf components that produce easily reproducible results. This protocol provides blueprints for the construction of sound attenuation chambers, the associated sound generation, amplification, and delivery equipment, and general procedures sufficient to elicit multimodal responses to loud noises in rodents. [摘要]  大多数生物体对突发性的环境刺激发生反应。 啮齿动物中的声音或大声噪声提供了有效的威胁信号,以研究负责制定通常由威胁/压力环境刺激引起的各种反应的中枢神经线路。 与其他环境刺激相比,声源压力提供了许多优势,包括精准的时序,强度和频率控制,使用现成的组件可以产生轻松重现的结果。 该协议提供了建立声音衰减室,相关的声音产生,放大和传送设备的蓝图,以及足以引起啮齿动物大声噪声的多模态响应的一般程序。
【背景】多年来,声源性压力(大声)被用作有效的刺激,以激活传统上与威胁状况​​和压力暴露有关的多模式反应,包括神经内分泌下丘脑 - 垂体 - 肾上腺皮质(HPA)轴(由糖皮质激素释放和促肾上腺皮质激素-ACTH; [Borrell等人,1980; Campeau和Watson,1997; Henkin和Knigge,1963; Segal等,1989)),自主神经系统(通过外周儿茶酚胺释放,心率,血液压力或核心体温测量; [Bao等,1999; De Boer等,1989; Gamallo等,1992; Masini等,2008; Overton等,1991; Saha等, 1996])和多相行为反应,最初引起有力的,快速回避的运动反应,然后在几分钟内通过显着减少或抑制运动活动,喂养和饮酒(Britton等人,1992; Campeau和Watson,1997 ; ...
