[The physiological indices of pre-examination stress].

The EEG spectral power characteristics and intracortical interactions were studied using brain mapping technique in students selected by their high level of anxiety and predisposition to stress. Before the examination, the activation of the anterior areas of the right hemisphere was higher than in norm by both indices. After the examination, the activation of these areas decreased. The obtained results, probably, reflect the neurophysiological dynamics of psychoemotional stress.
