“…This is because the bulk of the evidence comes from neuropsychological studies of callosotomy patients, rather than from behavioral studies of subjects without neurological insult. The neuropsychological studies simply report higher alexithymia scores in patients who have a surgically severed CC, or split-brain patients, compared to other populations [20]. Based on these studies, we cannot conclude that the problem in alexithymia is simply in the right-to-left transfer of processed emotion information.…”

Background: One neural model of alexithymia relates the condition to poor interhemispheric transfer, while another model associates it with a disturbance in right hemisphere activity. Methods: The available empirical evidence directly relating alexithymia to a deficit in interhemispheric transfer and/or in right hemisphere activity is critically reviewed. Results: The interhemispheric transfer studies have related alexithymia to a deficit in transfer, but the nature and directionality of the transfer deficit have yet to be determined. Many of the hemispheric specialization studies do not relate alexithymia to a right hemisphere dysfunction. Shortcomings of these studies are reviewed. Conclusions: The hypothesis that alexithymia is related to a deficit in the right-to-left transfer of emotional information and to a right hemisphere impairment in emotion processing remains to be tested directly and definitively. Suggestions for future research are made.

“…In this context suggestion can be made, that normal interrelationship between two hemispheres seems to be a prerequisite for favorable outcome of drug efficacy irrespective of used AEDs, since alexithymia as has been suggested may be caused by blockade between two hemispheres [28,29]. Nevertheless, the correlation between alexithymia and mentioned treatment outcome variables was too weak to make any definite and concrete statements about expected treatment results.…”

“…Here should be stressed, that alexithymia is thought to represent rather the single personality construct for which the possible explanation in terms of neuropsychological mechanisms exists [28,29]. A priori it could help us to understand the mechanisms of treatment process more properly.…”

“…In other words, a hypothesis has been suggested that complex of pre-morbid personality traits would be valid enough to predict the degree of seizure reductions or remission length. For this purpose the regression analysis has been used, since it can reveal the dependence of one variable on several independent ones [28,29].…”

Based on a review of numerous studies conducted on normal, neurosurgical and brain‐injured individuals, the right cerebral hemisphere appears to be dominant in the perception and identification of environmental and nonverbal sounds; the analysis of geometric and visual space (e. g., depth perception, visual closure); somesthesis, stereognosis, the maintenance of the body image; the production of dreams during REM sleep; the perception of most aspects of musical stimuli; and the comprehension and expression of prosodic, melodic, visual, facial, and verbal emotion. When the right hemisphere is damaged a variety of cognitive abnormalities may result, including hemiinattention and neglect, prosopagnosia, constructional apraxia, visualperceptual disturbances, and agnosia for environmental, musical, and emotional sounds. Similarly, a myriad of affective abnormalities may occur, including indifference, depression, hysteria, gross social‐emotional disinhibition, florid manic excitement, childishness, euphoria, impulsivity, and abnormal sexual behavior. Patients may become delusional, engage in the production of bizzare confabulations and experience a host of somatic disturbances such as pain and body‐perceptual distortions. Based on studies of normal and “split‐brain” functioning, it also appears that the right hemisphere maintains a highly developed social‐emotional mental system and can independentyly perceive, recall and act on certain memories and experiences without the aid or active reflective participation of the left. This leads to situations in which the right and left halves of the brain sometime act in an uncoopertive fashion, which gives rise to inter‐manual and intrapsychic conflicts.
