“…Another line of indirect evidence for a vasopressinergic role in attentional selectivity is provided by the findings that link the peptide to CNS activation: (a) The “electrophysiological profile” of humans treated with vasopressin resembles that produced by CNS stimulants such as amphetamine, caffeine, and adrenocorticotropin (ACTH; see Timset-Berthier, Mantanus, Devos, & Spiegel, 1982); (b) treatment with vasopressinlike peptides has been found to reduce reaction time (Durso et al, 1982; Fehm-Wolfsdorf et al, 1984); and (c) vasopressin activates the body's orchestrated response to stress, both by directly augmenting the release of ACTH from the anterior pituitary and by acting synergistically with corticotropin releasing hormone (CRH) in this action (Gillies, Linton, & Lowry, 1982; Mormede, Le Moal & Dantzer, 1985). Various treatments that increase an animal's level of arousal have been found to exert significant, and surprisingly uniform, effects on cue utilization.…”
