[Sleep and dreams in patients with parietal and frontal lobe lesions].

Polygraphic recordings, psychological tests, and analyses of dreams during paradoxical sleep were conducted in 9 patients with parietal lobe, in 7 with frontal lobe lesions and in a control group. No significant differences in sleep organization were observed in the parietal group, but there was a considerable reduction in oneiric activity and alterations in results of some psychological tests. Several correlations based on statistical data are discussed. Oneiric activity was disorganized to a much lesser degree in patients with frontal lesions.
