1993). In an investigation with tree shrews, chronic psychosocial stress evoked an increase in mineralocorticoid receptor mRNA content in CA1, CA3, and the dentate of the hippocampus (Meyer et al. 2001). Rats that underwent a stressor showed increased cortisol and ACTH levels following the administration of an mineralocorticoid receptor antagonist relative to nonstressed rats, suggesting that the upregulation of mineralocorticoid receptors in the stressed group is associated with increased inhibitory tone of the HPA axis (Gesing et al.

Norepinephrine, cortisol, and CRH thus appear tightly linked as a functional system that offers a homeostatic mechanism for responding to stress. Neurobiology of Emotional Memory Acquisition of fear-conditioned responses requires an intact central noradrenergic system, which suggests that norepinephrine release plays a critical role in fear learning (Charney and Deutch 1996). For at least some types of emotional learning, memory consolidation depends on noradrenergic stimulation of b- and a1-adrenergic receptors in the basolateral nucleus of the amygdala (Roozendaal 2000).

1998). Conversely, 5-HT2A receptor expression is upregulated during chronic stress and cortisol administration and is downregulated in response to adrenalectomy. There is increasing evidence for abnormalities in serotoninergic function in subjects with PTSD. Patients with combat-related PTSD had decreased platelet paroxetine binding, suggesting alterations in the 5-HT transporter. Challenge studies probing the serotoninergic system using meta-chlorophenylpiperazine (m-CPP) demonstrated that a subgroup of patients with PTSD develop anxNeurobiological Mechanisms of Psychological Trauma 25 iety and flashbacks on provocation with this agent (for review, see Southwick et al.
