Nine totally sleep deprived (TSD) and nine control subjects were evaluated with a complete battery for attention and memory performance. Frontal and temporal EEGs (5 min, eyes closed) were also recorded before and after the night. TSD subjects exhibited three performance deficits: learning the Pursuit Rotor Task, implicit recall of paired words, and distractibility on the Brown-Peterson Test. Relative to evening recordings, control subjects showed decreased morning absolute powers in all electrodes for all frequencies except for Frontal delta; TSD subjects showed increased Frontal and Temporal theta and Frontal beta. These results show that motor procedural, implicit memory, and working memory are sensitive to one night of TSD, and that Frontal and Temporal theta spectral power seem to discriminate between a night with sleep from a night without.
