A French team of experts headed by Mr. Henri Joyeux also undertook a very serious work of examination of the visionaries. Employing the most modern equipment and expertise, it examined the internal reactions of the visionaries before, during, and after the apparitions. Likewise, he synchronization of their ocular, auditory, cardiac, and cerebral reactions. The results of that commission were very significant. They showed that the object of observation is external to the visionaries, and that any external manipulation or mutual agreement between the visionaries is excluded. The results with individual electro-encephalograms and other reactions are collected and elaborated in a special book (H. Joyeux - R. Laurentin, Etudes medicales et scientifique sur les Apparitions de Medjugorje, Paris 1986).
The results of the last mentioned commission confirmed the conclusions of the international commission and, for their part, they proved that the apparitions, to which the visionaries testify, are a phenomenon that surpasses modern science and that all points toward some other level of happening.
