ABOUT THE CONNECTION BETWEEN VEGETATIVE NERVOUS SYSTEM TONUS AND FUNCTIONAL INTERHEMISPHERIC BRAIN ASYMMETRY AMONG PUPILS DEPRIVED OF HEARING

121 pupils of specialized boarding school for deaf children and children with poor hearing were examined. While the four year research of vegetative nervous system (VNS) tonus and individual display of functional interhemispheric brain asymmetry it was found out that the adaptation of deaf pupils and pupils with poor hearing happens with higher tonus of sympathetic section of vegetative nervous system than among pupils with good hearing. It was also found the connection between VNS tension with interhemispheric brain asymmetry and hearing factor.
