Behavioral task, CSF concentrations of 5-HTP and serotonin, and effect of 5-HTP on autonomic arousal. a Behavioral task and stimuli. Example social and non-social control images are seen on the right. b CSF concentration of 5-HTP. The central concentration of 5-HTP after i.m. injection of saline (blue), 20 mg/kg 5-HTP (green), or 40 mg/kg 5-HTP (red). c CSF concentration of serotonin. The central concentration of serotonin after i.m. injection of saline (blue), 20 mg/kg 5-HTP (green), or 40 mg/kg 5-HTP (red). d 5-HTP constricts the pupil. The percent change from saline in the size of pupil during the fixation period of trials during 20 mg/kg 5-HTP (green) and 40 mg/kg 5-HTP (red) sessions. In bc, the average CSF concentration per dose is represented by a colored line, and grey lines represent the standard error. In bd, Each shape represents an individual subject’s data
