Abstract

In view of the inhibitory influence of Mammillary Medial Nuclei, parslateralis (MMN) on corticoadrenal activity, experiments were conducted in order to determine whether these nuclei are involved in the control of adrenal response to ether stress. In bilateral MMN lesioned rats, prestress plasma corticosterone concentration (C) is significantly higher than that in sham lesioned animals. Acute stress produced a significant C increase in both, sham and lesioned rats, being this increase lower in lesioned animals. After exposure to ether vapors, adrenal concentration of norepinephrine was similar in lesioned and control animals. Whereas, adrenal epinephrine concentration was significantly higher in lesioned rats than that found in the sham lesioned ones. This study demonstrates that the integrity of MMN is not essential for adrenal response to acute stress.
