Table 3. Effects of command neuron ablations on undulation frequency, forward velocity and reverse velocity.

Values were computed separately for each worm and are shown as mean ± sem (n = 19–29 ). Undulation frequency was estimated as one-half of the reciprocal of the time of the first local minimum in the heading autocorrelation function. All p-values are from two-tailed t-tests and are shown without correction for multiple comparisons. Blue denotes significance at p<0.05. Red denotes significance at p<0.05 after Bonferroni correction for 15 comparisons.
