title: Brain Na+,K+-ATPase activity possibly regulated by a specific serotonin receptor.
abstract: Na+,K+-ATPase activity in 6 regions of adult brain was measured after incubation with varying concentrations of serotonin. A concentration-dependent increase in enzyme activity was observed in 4 regions, with cerebral cortex and cerebellum showing the largest response. These results together with previous ones suggest that serotonin modulates brain Na+,K+-ATPase activity through a specific receptor located in target neurons or glial cells.
