  • Data are based on at least eight worms per strain with 10 random traces per worm (trace duration = 5 sec). For analysis of M3 transients only isolated pumps with no other pumps within 200 msec were used. Each mean is presented ± SEM. Subthreshold MC activity is defined as recorded MC transients that failed to elicit a pharyngeal muscle action potential. MC activity was defined as nonsynchronous if the activity consisted of more than a single distinct transient.
