In the present study we examined the influence of arginine vasopressin (AVP) on conditioned freezing behavior to aversive shock treatment by comparing the responses of Brattleboro homozygous (DI) rats, Brattleboro heterozygous (HZ) rats, and Long-Evans (LE) rats. Each animal was placed in a sound-attenuated shock chamber on the training day and given a series of 3 footshocks. On the following 4 consecutive days the rats were placed in the chambers where they had received their shock and levels of spontaneous freezing were evaluated. Levels of circulating vasopressin-associated neurophysin (NP) were subsequently determined in each rat strain. For each of the 4 test days, DI rats displayed significantly less freezing behavior when compared with LE rats and HZ rats. HZ rats displayed trends towards attenuated freezing responses when compared with LE rats. The data indicate that a relationship exists between the levels of central nervous system (CNS) and circulating AVP, and the amount of freezing displayed by each strain. These preliminary results suggest that vasopressin may be involved in appropriate autonomic and emotional responses to fearful stimuli in fear conditioning paradigms.
