colocalization studies revealed that many presumed serotonin-synthesizing neurons in the raphe nuclei also contained sp-like immunoreactivity ( up to 30 % ) while few monoamine-synthesizing neurons in the lateral and dorsomedial medulla contained sp-like immunoreactivity ( approximately 5 % of presumed serotonin- , noradrenaline- , and adrenaline-synthesizing neurons ) .
