Abstract
Considering previous studies on EEG brain mapping in the course of saturati on dives, the authors studied the same standards of EEC performance during the compression phase of a saturation dive reaching -250 m. An increase of theta and beta rhythms was observed, especially in the midline anterior reg ions of the brain, during the entire compression period, while an increase of delta activity was noted only at -100 m. These results confirm our hypot hesis that the compression profile is physiologically correct, because the EEC modifications decreased during the stay at maximum depth.
