↵^aMorphometric properties of cells in which galanin (n = 18) or nNOS (n = 15) was detected. In all cases, mean values are shown. Soma depth is expressed as the percentage distance along the dorsoventral axis, with the dorsal white matter defined as 0% and the lamina II/III border as 100%. For both dendrites and axons, “extent” indicates the dimensions of the entire dendritic or axonal tree and “length” refers to the summed length of individual dendritic or axonal branches. RC:DV ratios were determined from the dorsoventral and rostrocaudal lengths of axons and dendrites.
