The effect of the new noradrenaline (NA) neurotoxin, DSP4, on the acquisition of one-way and two-way active avoidance responses was studied in rats. This treatment caused a marked degeneration of the locus coeruleus NA system and markedly impaired both one- and two-way avoidance acquisition. Both effects were blocked by pretreatment with desipramine, a NA uptake blocking agent. The present findings support the hypothesis that the locus coeruleus NA system in its entire extent may play a role in aversive learning.
