Line 72: − A CTA is the pairing of a toxic effect with a taste, flavor, or oral somatosensory stimulus. Historically, it has been very difficult to associate the effects of a interoceptive toxin with a conditioned stimulus that works through non-oral modalities (e.g. pairing a visual, auditory, or somatic stimulus with a toxic injection of LiCl).+

A CTA is the pairing of a toxic effect with a taste, flavor, or oral somatosensory stimulus.

An important consequence of this property is that CTA learning is relatively resistant to contextual conditioning or modulation. Context is a nebulous term refering to multimodal sensory input derived from the environment of the experiment as a whole. Thus the spatial properties, visual characteristics, ambient noise, etc. of the testing situation make up the context; but for CTA learning, the context is far less important than the orosenory stimulation. Thus, if the animals rejection of a food can be attributed to a learned response to contextual, non-orosensory stimuli, then the behavior is not due to CTA.
