Measurements were made in 29 adult baboons that were housed in social groups, allowing the occurrence of the full range of species-specific behavioral interactions. The cardiovascular variables measured included blood pressure, heart rate, renal blood flow, lower limb blood flow, and occasionally mesenteric blood flow. The data were telemetered from backpacks worn by the animals and were recorded in analogue form on a polygraph, digitally on a computer and were also recorded on the audio channels of videotape being made of the behavior and social interactions of the baboons. The video and the computer recordings were synchronized by a timing system that made it possible to relate the cardiovascular responses to the behavioral responses. A numerically based behavioral code was developed that allowed the categorization of the totality of the behavior, including postural and locomotor changes. Comparisons between baseline cardiovascular values and those occurring 1 s before the initiation of a movement or posture change gave no evidence of anticipatory cardiovascular responses unless the movement was associated with behavior that included emotional content. Hypothalamic perifornical lesions reduced or eliminated these anticipatory changes.
对29只成年狒狒进行了测量，这些狒狒群居在一起，呈现出该物种特有的各种行为互动。测量的心血管变量包括血压、心率、肾血流量、下肢血流量，偶尔也测量肠系膜血流量。数据通过动物佩戴的背包进行遥测，以模拟形式记录在测谎仪上，以数字形式记录在计算机上，还记录在狒狒行为和社交互动的录像带音频通道上。视频和计算机记录通过一个计时系统同步，这使得将心血管反应与行为反应联系起来成为可能。开发了一种基于数字的行为代码，用于对包括姿势和运动变化在内的所有行为进行分类。除非运动与包含情感内容的行为相关，否则基线心血管值与运动或姿势改变开始前1秒的心血管值之间的比较没有显示出预期的心血管反应迹象。下丘脑穹窿周病变减少或消除了这些预期变化。
