摘要
Subtypes of beta adrenoceptors were measured in 17 different areas of brain in rats exposed for 12 days to novel stressors. Mild stress such as individual housing and handling caused no change in beta1 and beta2 adrenoceptors in comparison with that measured in rats that were group housed and never handled. Exposure of rats to more severe stressors did reduce significantly the binding of I-125-iodopindolol (I-125-IPIN) to beta1 adrenoceptors, but not beta2 adrenoceptors, only in the lateral and basolateral nuclei of the amygdala.
