As a form of associative learning by which an animal avoids a novel taste or food that has been previously paired with a toxin, CTA has been widely used as a marker of aversive effects caused by drugs and treatments. CTA learning is remarkably sensitive, and often reveals a treatment effect even when no other behavioral effect is detectable. Purely exteroceptive sensory stimuli, such as light or auditory cues produced by the MF or the apparatus, are likely to be ignored because CTAs overwhelmingly favor a novel taste as the conditioned stimulus [53]. Likewise, stressful effects of the exposure procedure, such as restraint or cutaneous discomfort, are not sufficient to act as the unconditioned stimulus in CTA learning [39, 53]. Aversive effects that activate interoreceptors or induce nausea in humans, however, are favored to induce CTAs [53].
