Abstract--This article argues how dopamine controls work-
ing memory and how the dysregulation of the dopaminergic
system is related to schizophrenia. In the dorsolateral pre-
frontal cortex, which is the principal part of the working
memory system, recurrent excitation is subtly balanced with
intracortical inhibition. A potent controller of the dorsolateral
prefrontal cortical circuit is the mesocortical dopaminergic
system. To understand the characteristics of the dopaminer-
gic control of working memory, the stability of the circuit
