Emotion has long defied precise definition, but it is useful in a general sense to regard emotion as those mental activities approximately equivalent to ''feelings.'' Emotions are powerful motivators in human life and clearly have their origin in brain activity. The neurosciences heretofore have not devoted as much attention to emotions as to cognition, but data are accumulating to indicate that this large group of human afflictions can be understood in terms of disorders of the brain, including those affecting cerebral white matter. White matter systems in the frontal and temporal lobes are most directly involved with emotion, and in particular, those tracts intimately connecting structures of the limbic system are thought to be of primary importance. Many individuals with cerebral white matter lesions experience changes in emotional status. Depression appears to be the most common syndrome, and it may result from white matter lesions interfering with the activity of neuro-transmitter systems mediating mood as well as from the patient's psychological reaction to the disease. Other syndromes commonly encountered include bipolar disorder, emotional incontinence, euphoria, and psychosis. Because the study of neurobehavioral aspects of white matter is still in an early stage, more recognition and understanding of these and other syndromes is likely in the future.
