1.通过测量不同环境暴露后的直肠温度来研究雏鸡孵化后第0天至第30天（P0-P30）的恒温成熟情况。2．体温调节和类似成人的体温（41.5 摄氏度）随着不同的时间进程而发展，分别在 P4 和 P23 天成熟。在 20 摄氏度下 1 小时后，P0 雏鸡的温度比 P30 动物低 4.5-6.5 摄氏度。3。温度效应会将听觉通路中的频率移动最多 0.5 个八度至更低的值。在清醒雏鸡频率表征的发育研究中观察到的音位图的一些变化可以通过这种温度效应得到充分解释。
1. The maturation of homeothermy in chicks from day 0 to day 30 after hatching (P0-P30) was studied by measuring rectal temperatures following different environmental exposures.2. Body temperature regulation and an adult-like temperature (41.5-degrees-C) develop with different time courses, being mature on days P4 and P23, respectively. After 1 hr at 20-degrees-C, P0 chicks were 4.5-6.5-degrees-C cooler than P30 animals.3. A temperature effect shifts frequency in the auditory pathway up to 0.5 octaves to lower values. Some shifts in tonotopic maps observed in developmental studies of frequency representation in awake chicks can be fully explained by this temperature effect.
