The two hemispheres are specialised in both different emotions and methods of dealing with stress and have different roles in controlling the heart. The main factor in the sudden cardiac death seems to be stress and the sudden rising sympathetic dominance of the left brain on heart. The right hemisphere's leading role in anxiety disorders can be understood because of being specialised in negative emotions, and furthermore its dominant position in perceiving and modulating of heart sheds new lights on the aetiology of symptoms and fears related to heart in panic disorder, agoraphobia and cardiophobia. Besides these important questions the hemispheric dynamic model of anxiety, the aetiology of panic attack, and the main personality traits being regarded as a risk of getting cardiovascular disorders are also discussed.

The essence of this modell is that at the beginning of hypnosis induction an increased left frontal activation can be detected, however later during the steady state the frontal activation gradually decreases bilaterally, being more expressive on left, and the activation of the posterior brain areas becomes more intensive. Findings from PET, SPECT, fMRI studies show that the changing activation of anterior cingular, inferior parietal and occipital cortex plays important role in hypnotic states. From these studies we can come to the conclusion that hypnotic suggestion modifies the low level neural process of sensory functions, not merely at the level of experience. It can be expected that these new findings radically change our views on hypnosis, and it would be a further step toward the integration between social and biological theories of hypnosis.

After a short review of the development of the concept of hysteria we summarize the newest neurobiological findings in conversion hysteria and point out the similarities between conversion and hypnotic phenomena. The relationship between trauma and conversion symptoms is also discussed on neurobiological basis. Finally we review Oakley’s unifying model of hysteria and hypnosis.

Several other lines of inquiry provide converging evidence for a critical role for the right cerebral hemisphere in negative emotions and depression. A third area of the research studying the concordance of atopic diseases and affective disorders suggests a relationship between these disorders. These connections between right hemisphere dominance, atopic diseases and affective disorders involve that atopic symptoms mediated by the increased level of IgE might be related to right hemisphere dominance. In this review it is hypothesised that the dominant right brain activated by early negative experiences, inherited vulnerability and other factors might determine developing atopic state and later the right hemisphere mediates between the influence of the environmental stress and the immune system maintaining or rather worsening atopic states.
