Sumario:The aim of the present study was to review and update historical controversies in relation to the limbic system in light of advances in the neuroanatmy and neurobiology of cortico-striatal-thalamic-cortical (CSTC) neural circuits. It is hypothesized that observed comorbidities between internalizing and externalizing childhood syndromes may be better understood in terms of excess communication between subcortical brain circuits. A neuroanatomical understanding of reciprocal and non-reciprocal connections between modular circuits provides a basis for understanding previously puzzling aspects of internalizing, externalizing comorbidity. Function depends on the degree of cooperative integration of goal orientation, Pavlovian stimulus response, and operant processing in cortical-subcortical circuits, and interventions may be targeted at any of these functions.
