Our study was devoted to determine in freely moving rats whether the increase in tissue concentration of tyrosine hydroxylase (TH) elicited by a single administration of RU 24722 could modify the catecholaminergic reactivity of neuronal processes present in the rostrolateral part of the pericerulean area (r-lPCA) in response to tail pinch. Catecholaminergic(More)
Traumatic brain injury (TBI) is common in both military and civilian populations, and often results in neurobehavioral sequelae that impair quality of life in both patients and their families. Although individuals who are chronically exposed to stress are more likely to experience TBI, it is still unknown whether pre-injury stress influences the outcome(More)
Noradrenaline (NA) released by dendrites of locus coeruleus (LC) neurons controls LC neuron activity, and hence, NA released from noradrenergic fibers in terminal fields. NA synthesis is dependent on tyrosine hydroxylase (TH), whose dendritic presence is controlled precisely in LC neurons during postnatal development. However, the mechanisms controlling(More)
