Abstract
The administration of lithium carbonate for 5 days to rats increased the synthesis rate of brain serotonin, without modifying the brain level of the amine. This increase was not due to a modification of the free tryptophan in the blood. The level of serotonin and 5 HIAA remained unchanged in seven areas of brain. These results are discussed in comparison with the results of the other authors on the same subject.
