Figure 4

(a) 5-HT1A is expressed by vPNs (green). (b) 5-HT1A expressing vPNs (green) colabel for GABA (magenta). (c) 5-HT1A expressing vPNs colabel for choline acetyltransferase (ChAT; magenta). (d) 5-HT1B is expressed by vPNs (green). (e) 5-HT1B expressing vPNs (green) colabel for GABA (magenta). (f) 5-HT1B expressing vPNs colabel for ChAT (magenta). (g) 5-HT2A is expressed by vPNs (green). (h) 5-HT2A vPNs (green) colabel for GABA (magenta). (i) 5-HT2A vPNs (green) colabel for ChAT (magenta). (j) 5-HT2B expressing vPNs (green). (k) 5-HT2B vPNs (green) colabel for GABA (magenta). (l) 5-HT2B vPNs (green) colabel ChAT (magenta). (m) vPNs that express 5-HT7 (green). (n) 5-HT7 vPNs (green) co-label for GABA (magenta). (o) 5-HT7 vPNs (green) colabel for ChAT (magenta). Regions of neuropil in (a), (d), (g), (j) and (m) are delineated by α-Bruchpilot (α-Brp; magenta) labeling. All scale bars = 10 um.
