Abstract

In the present study, we measured the striatal serotonin content of weaver and control mice at different ages. Overall, weaver mutant mice exhibited 50% more striatal serotonin than controls. Neither a rostrocaudal gradient nor an age effect was found for either genotype. An analysis of serotonin content across the dorsoventral extent of the striatum revealed that in the dorsal striatum of the weaver, serotonin content was increased 200%, and in the ventral striatum, the increase amounted to 50% relative to control mice. Serotonin immunocytochemistry also revealed an increase in the dorsal striata of weaver mice. The major increase in striatal serotonin content seen in the weaver striatum occurs in the same region that exhibits the severest dopamine depletion. This observation is consistent with the notion that the increase in serotonin levels may be secondary to the decrease in dopamine content and may play an adaptive or compensatory role.
