Early-life stress disrupts attachment learning: the role of amygdala corticosterone, locus ceruleus corticotropin releasing hormone, and olfactory bulb norepinephrine.
Infant rats require maternal odor learning to guide pups' proximity-seeking of the mother and nursing. Maternal odor learning occurs using a simple learning circuit including robust olfactory bulb norepinephrine (NE), release from the locus ceruleus (LC), and amygdala suppression by low corticosterone (CORT). Early-life stress increases NE but also CORT, and we questioned whether early-life str...
متن کاملThe role of olfactory bulb norepinephrine in early olfactory learning.
Wistar rat pups were implanted with bilateral olfactory bulb cannulas on postnatal day 5 (PN5). On PN6, pups were trained in an olfactory classical conditioning task with peppermint odor as the CS and tactile stimulation/stroking as the UCS. Pups were randomly assigned to either PAIRED, BACKWARD or ODOR-only conditions. Half the pups in each group received intrabulbar infusions of 100 microM pr...
متن کاملCorticotropin-releasing hormone directly activates noradrenergic neurons of the locus ceruleus recorded in vitro.
The neuropeptide corticotropin-releasing hormone (CRH) activates locus ceruleus (LC) neurons, thereby increasing norepinephrine levels throughout the CNS. Despite anatomical and physiological evidence for CRH innervation of the LC, the mechanism of CRH-evoked activation of LC neurons is unknown. Moreover, given the apparent absence of mRNA for CRH receptors in LC neurons, the exact location of ...
متن کاملNorepinephrine and Corticotropin-Releasing Hormone: Partners in the Neural Circuits that Underpin Stress and Anxiety
Norepinephrine and corticotropin-releasing hormone (CRH) have long been implicated in the response to stress. In this issue of Neuron, McCall et al. (2015) show that CRH projections from the central amygdala drive tonic locus coeruleus activity that evokes acute anxiety responses and place aversion.
متن کاملInvolvement of stress-released corticotropin-releasing hormone in the basolateral amygdala in regulating memory consolidation.
It is well established that adrenal stress hormone-induced activation of the basolateral complex of the amygdala (BLA) influences memory consolidation. The present experiments investigated the involvement of corticotropin-releasing hormone (CRH) in the BLA in modulating memory consolidation. Bilateral infusions of the CRH receptor antagonist [9-41]-alpha-helical CRH (0.3, 1.0, or 3.0 microg in ...
