Nine totally sleep deprived (TSD) and nine control subjects were evaluated
with a complete battery for attention and memory performance. Frontal and t
emporal EEGs (5 min, eyes closed) were also recorded before and after the n
ight. TSD subjects exhibited these performance deficits: learning the Pursu
it Rotor Task, implicit recall of paired words, and distractibility on the
Brown-Peterson Test. Relative to evening recordings, control subjects showe
d decreased morning absolute powers in all electrodes for all frequencies e
xcept 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 Fro
ntal and Temporal theta spectral power seem to discriminate between a night
with sleep from a night without. (C) 2000 Academic Press.
