Abstract
Photoperiodic influences on cAMP concentrations in the preoptic region and parietal cortex of the rat were studied at different ambient temperatures. In the preoptic region a photoperiodic rhythm is present at control Ta (22 degrees C) and is strongly attenuated at low Ta (-10 degrees C). In the parietal cortex no statistically significant photoperiodic changes were observed either at control or low T(a)s.
摘要
在不同环境温度下研究了光周期对大鼠视前区和顶叶皮质中环磷酸腺苷（cAMP）浓度的影响。在视前区，在对照环境温度（22摄氏度）下存在光周期节律，而在低温环境温度（-10摄氏度）下该节律强烈减弱。在顶叶皮质中，无论在对照环境温度还是低温环境温度下，均未观察到具有统计学意义的光周期变化。
