Locoweed poisoning in sheep: electroencephalographic and brain amine changes.
The effects in sheep of locoweed poisoning on electroencephalograms and on levels of the brain amines serotonin and norepinephrine were measured. Lucoweed-induced EEG changes in sheep were characterized by episodes of high voltage, slow activity (HVSA). There was no effect on brain norephinephrine levels. The mean brain serotonin level of the sheep fed locoweed was approximately 57% higher than the control but was not significant.
