The average dopamine transporter density proportional to the counts per pixel in the right (R) and left (L) striatum of control and sleep deprived groups. The scans were performed at baseline, after the respective total or REM sleep deprivation protocol, and after three nights of sleep recovery.

R Striatum	Baseline	Sleep Deprivation	Recovery
Control	2.3 ± 0.2	2.3 ± 0.2	2.1 ± 0.2
REM Sleep Deprivation	2.2 ± 0.3	2.1 ± 0.3	2.1 ± 0.3
Total Sleep Deprivation	2.4 ± 0.2	2.3 ± 0.3	2.3 ± 0.3
L Striatum
Control	2.2 ± 0.3	2.3 ± 0.2	2.1 ± 0.3
REM Sleep Deprivation	2.2 ± 0.3	2.1 ± 0.2	2.2 ± 0.3
Total Sleep Deprivation	2.5 ± 0.3	2.4 ± 0.4	2.3 ± 0.4

The data are shown as mean ± SD (n = 10 volunteers per group). R Striatum, Right Striatum; L Striatum, Left Striatum.
