Ventilation of septum removed (SR)- (triangles) and sham-operated (SO)-tegus (circles) resting during the night (open symbols) and at rest and activity during the day (filled symbols). The start of exercise at 0.17 m s-1 and the beginning of the recovery period after exercise at 0.28 m s-1 are defined as zero. Exercise at 0.17 m s-1 (grey bar) was terminated after 5 min, whereas exercise at 0.28 m s-1 (black bar) lasted until exhaustion of the animal.
