Figure 14. Dendrite length and branching in 5-HT neurons across raphe subfields.

Figure 14

(A) The number of primary dendrites (dendrites extending directly from the soma) did not differ across subfield. (B–C) The number of ends and branch points of 5-HT neurons showed a range of variability across the subfields. The dendritic arbor varied between individual neurons within the MR and vmDR, indicating a greater variety in the dendritic architecture of cells within these subfields. In comparison, dendritic arbors of individual neurons within the lwDR and dmDR 5-HT were similar within each subfield. (D) The total dendritic length of neurons in the MR was shorter than that of all the other subfields (*p<0.05). N=11–14 neurons/group.
