For the majority of stimuli that can induce CTA, the peripheral or central brain sites that are sufficient or necessary for CTA acquistion are not well defined. Furthermore, the time course of the toxin’s effect is very fuzzy. We know the duration of the taste stimulus, from when a rat starts licking until it stops licking at the solution (or when we stop an intraoral infusion of a taste). While we can control the onset of illness (the time we inject the LiCl), we can’t control the termination of the toxic effect,because we can’t remove all the toxin from the blood abruptly, nor can we specify the exact time the rat is no longer feeling sick.
