Values are mean ± SEM. The level of significance between ventral and dorsal was determined using Scheffé’s post hoc test following a single-factor ANOVA test (*p < 0.05, **p < 0.01, ***p < 0.001). ^aSignificant differences between dVNLL onset-type and dVNLL sustained firing neurons. ^bSignificant differences between dVNLL sustained firing and vVNLL neurons. ^cSignificant differences between vVNLL and dVNLL onset-type firing neurons.
