Photoperiodic rhythm of cAMP concentration in the rat's preoptic region
Bollettino Della Societa Italiana Di Biologia Sperimentale
|September 15, 1980
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.
