The swimming motor program (SMP) network in Tritonia consists of approximately 65 neurons. These can be divided into regularly bursting (RB, yellow circle, orange/red numbers), variably bursting (VB, blue circle, green numbers) and nonbursting (pink circle, blue numbers). During sensitization, both VB and NB neurons are converted to RB neurons, such that the number of RB neurons is increased. Following loss of sensitization, there is a return to the basal number of RB, VB and NB neurons, but the actual composition of neurons is different, with some previously RB neurons now in the VB or NB category, some VB neurons now in the RB or NB category, and some NB neurons now in the VB or RB category.
