[Differential implication of cerebral hemispheres in emotional behavior (author's transl)].

Current neuropsychology states that the right cerebral hemisphere is dominant in emotional situations and emotional responses. The author suggests that various results must clarify this concept. This predominance seems to be prevalent in negative emotions, while positive emotions are mainly processed through the left hemisphere. There is thus no hemispheric asymmetry but rather a hemispheric differentiation in function of the nature of the emotion. The explanation of this double asymmetry remains to be clarified.
