A) Anatomical location of each neuron subtype that receives a synaptic input from the PB subregion (red) superimposed on those without a detectable input from the PB subregion (blue). E- and E-aug neurons are pooled. B) Comparison of the location rostral to obex caudal and the depth locations of neurons with (red) and without (blue) synaptic inputs. Number of neurons for each subtype below the left bar graph. Statistical comparisons show that pre-I neurons receiving inputs were rostral (left graph) and deeper (right graph) than those without inputs. Differences in depth were seen for I-aug, E-aug and E neurons. See text for details.
