Dynamics of maximal value of simultaneously recorded neuronal responses after training in vitro in the silent parietal giant premotor interneurons (amplitude of maximal depolarization in an interval 15–25 sec after the juice application was scored), and in the spontaneously active pedal #4 serotonergic neurons (maximal frequency of action potentials in an interval 15–25 sec after the juice application was scored) in response to 5 consecutive applications of carrot juice with 5 min intervals.
Example from a single experiment.
