We look at individual features of brain neurodynamics in test-cosmonauts at different stages of adaptation to the conditions of long-term isolation in the Ground experimental complex. Special attention is paid to the reaction of participants of 90- and 120-day experiments to emergencies (accidents concerning the life support systems) as well as the dynamics of interpersonal relationships. We present the data connected with the role of personal attitude collected at the final stage of the experiment. The prognostic significance of the assessment of individual stress resistance and group compatibility for the selection of people for further work in the conditions of autonomous existence of small groups (cosmonauts, submariners, polar explorers, small military units) is shown.
