For 5 days, rats were exposed to shocks that were signalled by a light 0, 33, 66, or 100% of the time. Basal hormone levels and responses to a light-shock pair were measured daily. Greater predictability was associated with higher basal plasma cortic

This study examined the effects of aging and chronic congestive heart failure on plasma corticosterone and cortisol levels in hamsters. It also assessed the effects of aging and heart failure on glucocorticoid responses to acute and chronic stress. A

Some earlier work, not rigorously controlled, suggested that conditional increases in sympathoadrenal stress hormones could occur. The purpose of this experiment was to test this idea further using an appropriately controlled design. To do this, we s

This experiment was designed to study the effect of stressor intensity on habituation/sensitization of the adrenocortical stress response in rats. Rats were given 18 shocks in 3-hr daily sessions for 8 days, and a single shock probe before the sessio

Research in chronic stress has been hampered by the absence of an operational definition for that condition. To explore possible criteria for chronic stress, we repeatedly exposed rats to 2 hr of tail shock per day. After several days, we found eleva

This study measured plasma corticosterone levels in male rats during repeated daily presentations of two intensities of restraint stress. The corticosterone response to a stress session was defined as the change from pre-stress levels to levels after

When individual rats were exposed to different intensities of a stressor, foot shock, plasma catecholamines were found to be sensitive and reliable indices of the stress. Plasma corticosterone did not perform as well. Similarly, levels of both plasma

The present studies were conducted to demonstrate classical aversive conditioning of a corticosterone stress response in male rats. In the first experiment animals exposed to an odor which had previously preceded tube restraint stress had significant

On an every other day basis, chronically catheterized male rats were subjected to a 30 sec grid shock in either an ascending (0.0, 0.25, 1.0, 4.0 mA) or descending order. A third group was repeatedly subjected to 1.0 mA shock over the same time frame
