title: [Results of a study of vestibular function and space perception among members of the crew of the first and second "Sal'iut 6" space station expedition].
abstract: The results of studies of the vestibular function and spatial perception function in crewmembers of long-term (96- and 140-day) space missions aboard Salyut-6 are presented. Similar changes and individual variations are revealed. All the cosmonauts have shown the following changes: increased reactivity of the otolith organ, decreased sensitivity of the cupular system, asymmetry of most parameters studied, and illusory reactions inflight, individual reactions are as follows: level of changes, dynamics and time of recovery, development of vestibulo-vegetative symptomocomplex during early adaptation to zero-g, signs of decline in vestibulo-vegetative tolerance postflight, and changes in reciprocal relations between the otolith organ and semicircular canals.
