title: REM sleep eye movement activity and CSF concentrations of 5-hydroxyindoleacetic acid in psychiatric patients.
abstract: The relationship between rapid-eye-movement (REM) sleep tonic and phasic activity measures and the pre- and postprobenecid cerebrospinal fluid (CSF) concentrations of the serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA) was examined in a sample of 14 unmedicated psychiatric patients. The average duration of an eye movement burst and the average number of eye movements within a burst were found to be inversely related to the probenecid corrected accumulation of 5-HIAA in the CSF. These results are interpreted as indicating an association between REM burst eye movement activity and serotonin turnover in psychiatric subjects.
